Agenda Item 1 2 Power Limits for MSS MetSat EESS Earth Stations Around 400 MHz. SFCG supports establishment of appropriate in band e i r p limits for earth stations operating in. mobile satellite service 399 9 400 05 MHz the meteorological satellite service 401 403 MHz . and the Earth exploration satellite service 401 403 MHz in order to preserve on a long term. basis the operation of Data Collection Systems of both NGSO and GSO systems SFCG does not. support the use of e i r p density limits as a mechanism for ensuring compatibility In addition . for both frequency bands SFCG supports not applying the corresponding limit to satellite. systems for which complete notification information has been received by the. Radiocommunication Bureau by 22 November 2019 ,APT Preliminary Position. 2019 08 06 APT Members support the ITU R studies in accordance with Resolution 765 WRC 15 on. establishing in band power limits given in section 4 1 2 3 1 and 4 1 2 3 2 of CPM AI 1 2 report . for earth stations required to protect satellite system with lower or moderate power e g DCS . from harmful interference from telecommand link earth stations operating in the EESS and. MetSat in the frequency band 401 403 MHz and the MSS in the frequency band 399 9 . 400 05MHz , For the band 399 9 400 05 MHz, APT Members support Method C in the CPM Report for this Agenda Item and support the.
e i r p limit indicated in Table 4 1 2 3 1of the CPM Report APT Members are of the view that. transitional period until 22 November 2024 are needed to ensure that the existing telecommands. for EESS systems including those systems to be notified before November 22 2019 may. continue to operate , For the band 401 403 MHz, APT Members support Method E in the CPM Report for this Agenda Item APT Members are of. the view that transitional arrangements are needed to ensure that the existing telecommands for. EESS including those systems to be notified and brought into use before November 22 2019 . may continue to operate until November 22 2024 or 2029 date to be agreed on at WRC 19 . Some APT Members are of the view that telecommand links for all of the existing satellite. systems in operation under EESS are necessary to be ensured continuously until November 22 . 2029 Therefore some APT Members support the Method E of the CPM Report with a transition. period for applying the relevant e i r p limits of up to November 22 2029 in this band . ASMG Preliminary Position, 2018 12 13 Follow up the ongoing studies in the ITU R . Supporting the ongoing studies in order to establish in band power limits for earth stations. operating in Mobile satellite service MSS Meteorological satellite service MetSat and Earth. exploration service in the frequency bands 401 403MHz and 399 9 400 05MHz in order to. ensure the protection of the existing services without imposing any additional constraints in. these services due to the massive usage of the fixed and mobile services in these frequency bands. in the countries ,ATU Preliminary Position, 2018 09 17 APM19 3 agreed to . a For the band 399 9 400 05 MHz , Agenda Item 1 2 Power Limits for MSS MetSat EESS Earth Stations Around 400 MHz. Note that ECOWAS and EACO positions is Method A no Change . Note that Egypt position is to support Method B, Note that SADC was still considering the issue and therefore did not have a common.
b For the band 401 403MHz , Note that ECOWAS and Egypt positions is to support Method E . Note that EACO position is to support No Change, Note that SADC was still considering the issue . CEPT European Common Proposal ECP adopted, 2019 05 24 Position. In order to ensure long term continuity for the operation of satellite data collection systems . CEPT supports the establishment of in band e i r p limits as appropriate for earth stations in the. EESS and MetSat in the frequency band 401 403 MHz for GSO and non GSO and in the MSS. frequency band specified per emission within reference bandwidth 4 kHz as well as within. whole allocated band to avoid possible power aggregation of closely spaced narrowband. carriers notified for earth stations taking into account the result of studies . In addition CEPT proposes specific provisions for frequency band 399 9 400 05 MHz until. 22 November 2024 and for frequency band 401 403 MHz until 22 November 2027 for existing. and planned satellite systems exceeding these e i r p limits for which complete notification. information has been received by the Radiocommunication Bureau and that have been brought. into use before 22 November 2019 , The ECP and the CEPT position are based on the following Methods from the CPM Report . Method for the 399 9 400 05 MHz band Method E for the 401 403 MHz band . CITEL Draft Inter American Proposal, 2019 04 12 Resolution 765 WRC 15 calls for the necessary technical operational and regulatory.
consideration of the possibility of establishing in band power limits for earth stations in the EESS. and MetSat services in the frequency bands 401 403 MHz and in the MSS frequency band 399 9 . 400 05 MHz taking into account the results of ITU R studies . The frequency bands 401 403 MHz and 399 9 400 5 MHz are used for Earth station uplink. transmission by the Data Collection System DCS under the Earth exploration satellite service. EESS and meteorological satellite service MetSat and the mobile satellite service MSS . allocations DCS Earth stations as knows as data collection platforms DCP are deployed. worldwide and communicate with GSO and non GSO satellites . The Data Collection Platforms DCP is a network of sensors measuring and gather information. activity related to the Earth environmental and scientific applications weather environment. observation meteorological and oceanographic seismic observation volcanology geodesy and. geodynamics fishing vessel monitoring wildlife tracking homeland security law enforcement . test evaluation monitoring shipments of dangerous goods humanitarian applications managing. water resources or tsunami warning system , The data collected by DCPs are transmitted to GSO and non GSO satellite networks using the. non GSO MSS allocation in the band 399 9 400 05 MHz or the meteorological satellite. allocation in the band 401 403 MHz These systems usually operate using moderate to low. equivalent isotropically radiated power e i r p levels resulting in small link margins . These frequency bands are also used by non geostationary satellites for telecommand space. operations see RR No 1 23 under the EESS MetSat services or under the MSS allocations and. a growing number of these satellites are planned The output power levels of the earth stations at. the antenna port peak e i r p of these telecommand links Earth to space can be much higher than. Agenda Item 1 2 Power Limits for MSS MetSat EESS Earth Stations Around 400 MHz. the moderate to low power levels used for the DCS service links leading to potential harmful. interference to DCS satellite receivers , Recommendation ITU R SA 2045 provides information on the performance and interference. criteria for relevant geostationary satellite orbit GSO and non geostationary satellite non GSO . DCS in the frequency band 401 403 MHz Recommendation ITU R SA 2044 provides. information on the current and future usage of non GSO DCS in the frequency band 401 403 MHz . and the portioning of the frequency band to allow all DCS equal access to the spectrum . Recommendation ITU R M 2046 provides a description and the corresponding protection criteria. for broadband noise and narrowband interference of one MSS system that uses the frequency band. 399 9 400 05 MHz Earth to space , ITU R studies considered in band power limits for earth stations operating in the frequency. ranges 399 9 400 05 MHz in the MSS and 401 403 MHz in the EESS and MetSat services . RCC Preliminary Position, 2019 01 25 The RCC Administrations support measures to study this issue and establish emitted power. limits for earth stations used for space operation functions in the frequency bands 401 403 MHz. and 399 9 400 05 MHz in order to avoid interference to data collection systems in the. meteorological satellite service Earth exploration satellite service and mobile satellite service. taking into account the Report ITU R SA 400 MHz LIMITS . The RCC Administrations consider that specified limits shall not cover the frequency. assignments to satellite systems registered in MIFR before 22 November 2019 in frequency. bands 399 9 400 05 MHz and 401 403 MHz during the transition period spanning not less than 5. years following WRC 19 At the same time equivalent isotropically radiated power limit for. earth stations of the existing satellite data collection systems operating in the frequency band. 401 898 402 522 MHz for which complete notification information has been received by the. Radiocommunication Bureau by 28 April 2007 can be increased to 12 dBW . Agenda Item 1 3 MetSat Upgrade EESS Allocation space to Earth at 460 470 MHz. Agenda Item 1 3 MetSat Upgrade EESS Allocation space to Earth at 460 470 MHz. SFCG supports raising the regulatory status of MetSat and EESS space to Earth allocations as. proposed by Method B of the draft CPM text ITU R WP 7B Chairman Report 7B 326 Annex 2 . SFCG recognizes the need for harmonization of the global operating environment to allow full. development of critical MetSat EESS systems SFCG is of the opinion that the MetSat space to . Earth allocation should be upgraded from secondary to primary status and a primary EESS space . to Earth allocation should be added in the frequency band 460 470 MHz while providing. protection for and not imposing any additional constraints on existing primary services to which the. frequency band is already allocated This should be realised while retaining the priority of MetSat. over EESS as currently expressed in the RR The SFCG supports the pfd mask for non GSO. satellites contained in Method B of the draft CPM text and encourages SFCG member agencies to. further develop a suitable pfd mask for GSO satellites . APT Preliminary Position, 2019 08 06 Some APT members support Method C while some other APT members support Method B of the.
CPM Report , Some APT members are of the view that pfd limits are to be revised for both non GSO and GSO. MetSat EESS satellites to give additional protection needed by mobile services that require higher. protection based on further ITU R studies , Reasons APT Members did not reach an agreement to develop specific proposed. regulatory text for Agenda item 1 3, ASMG Method A No changes are proposed to the RR A consequential suppression of Resolution 766. 2018 12 13 , ATU Preliminary Position, 2018 09 17 APM19 3 agreed to take Method A No change as the African preliminary position . CEPT ECP adopted, 2019 05 24 Position, CEPT supports that the MetSat space to Earth allocation should be upgraded from secondary.
to primary status and that a primary EESS space to Earth allocation should be added in the. frequency band 460 470 MHz provided that, the protection of primary services in the frequency band and in adjacent frequency bands. is ensured by the introduction of regulatory provisions including relevant pfd masks for. GSO and non GSO satellites, MetSat and EESS earth stations shall not claim protection from stations in the fixed and. mobile services as stated in recognizing f of Res 766. priority of MetSat over EESS as currently expressed in the RR is retained . CEPT position and ECP are based on Method C of the CPM Report . CITEL Preliminary Position, 2019 04 12 NOC ARTICLE 5 SUP RESOLUTION 766 WRC 15 . Reason proposing not to introduce to the Radio Regulations in the 460 470 MHz. frequency band can guarantee the current and planned use of this band for the. deployment of mobile service IMT systems , Agenda Item 1 3 MetSat Upgrade EESS Allocation space to Earth at 460 470 MHz. Draft Inter American Proposal, Inclusion in the Table a primary EESS space to Earth and MetSat allocation in the frequency.
band 460 470 MHz provision of protection to the fixed and mobile services from MetSat and. EESS satellite downlinks provision of protection to MetSat downlinks from EESS satellite. downlinks and replaces RESOLUTION 766 with a new Resolution to provide the transitional. measures for the existing Metsat EESS frequency assignments to ensure that the existing satellite. systems including those for which complete notification information or coordination request. was received by the Radiocommunication Bureau prior to the end of WRC 19 can continue their. operation in compliance with the provisions adopted at WRC 19 as well as to provide the. definition of pfd limits that will protect the terrestrial services . RCC Preliminary Position, 2019 01 25 The RCC Administrations support upgrading the secondary allocation to the meteorological . satellite service space to Earth to a primary status as well as a primary allocation to the Earth. exploration satellite service space to Earth in the frequency band 460 470 MHz under the. following conditions , upgrading the status of allocations of the frequency bands to the meteorological satellite. service and the Earth exploration satellite service shall be applied both for future systems. as well as existing systems of these radio services . for the protection of the terrestrial services to which the frequency band 460 470 MHz is. allocated on a primary basis which ensure acceptable interference level pfd limits for. the specified satellite services shall be established to ensure acceptable interference level . In case of non compliance with these limits existing satellite systems of specified. services can be used on the primary basis provided that no interference is caused to. stations in terrestrial services and they do not claim protection from stations in terrestrial. maintaining priority of the meteorological satellite service over the Earth exploration . satellite service should be ensured , The RCC Administrations do not support segmentation of the frequency band 460 470 MHz for. geostationary and non geostationary satellite systems . Agenda Item 1 5 Earth Stations in Motion at 17 7 19 7 GHz 27 5 29 5 GHz. Agenda Item 1 5 Earth Stations in Motion at 17 7 19 7 GHz 27 5 29 5 GHz. SFCG does not oppose the use of the 17 7 19 7 GHz by earth stations in motion communicating. with geostationary space stations in the fixed satellite service as per Method B of the draft CPM. text ITU R WP4A Chairman Report 4A 826 Annex 28 provided that the protection of the. EESS passive is ensured SFCG notes that the introduction of ESIM for maritime and. aeronautical use in the sub band 18 6 18 8 GHz may change the sharing environment with. EESS passive over the ocean area , APT Preliminary Position. 2019 08 06 Based on input documents from APT Members modifications to Draft New Resolution A15 . were discussed APT members developed a PACP which is essentially Method B with Option 1. for footnote 5 A15 and numerous other modifications to the draft resolution A15 or selections. amongst options including a new recognizing c bis article as follows . c bis that the successful compliance of this Resolution does not oblige any administration to. authorize licence any ESIM to operate within the territory under its jurisdiction unless such an. operation it fully complies with its national jurisdiction . In a number of areas of the PACP consensus was not reached including for Annexes . Annex 1 to A15 With respect to emission bandwidth larger than 100 MHz and the maximum. ESIM on axis e i r p no consensus was reached on any of two options contained in the CPM 19 . Annex 2 to A15 With respect to protection to terrestrial service by any type of ESIM using. Annex 2 with its pfd approach including various options providing modality how to implement. these options as contained in CPM Report no consensus was reached at APG19 5 meeting . However 2 approaches were proposed , Approach 1 Establish of pfd mask limit which shall not be exceeded on any point at the earth.
Approach 2 Establish of altitude limit below which aircraft on which ESIM operates shall not. Annex 3 to A15 No consensus was reached on this matter therefore no PACP is proposed in. this regard , ASMG Method B Add a new footnote in RR Article 5 that refers to a new WRC Resolution A15 . WRC 19 with technical operational and regulatory conditions for the operation of ESIM while. 2018 12 13 , ensuring protection of allocated services and consequential suppression of Resolution 158. ATU Preliminary Positions, 2018 09 17 APM19 3 agreed to . Take Method B as the African preliminary position which includes addition to a new footnote in. Article 5 of the Radio Regulations with reference to a new resolution which will define. operational and regulatory conditions for ESIMs incl pfd mask to protect terrestrial services in. the band 27 5 to 29 5 MHz from aircraft ESIM and an offshore separation distance to protect. terrestrial services from maritime ESIM , Note that there is an increasing need for mobile satellite broadband communications to. support the broader agenda of enhancing broadband . Note that the study results conducted in EACO SADC and Senegal show that sharing. and compatibility between the three types of ESMIs and existing terrestrial services. allocated in the bands is feasible and therefore support the identification of the. Agenda Item 1 5 Earth Stations in Motion at 17 7 19 7 GHz 27 5 29 5 GHz. frequency bands 17 7 19 7 GHz and 27 5 AND 29 5GHz to the different types of. Note the positive study result both in ITYU R WP4A and the sub regions and countries. that identification of the frequency bands 17 7 19 7 GHz and 27 5 29 5GHz for. ESIM operations can be supported whilst ensuring protection of and not imposing. undue constraints on other existing primary services allocated to these frequency. Invite sub regions and African countries to, Continue exploring different solutions ie the operational and regulatory conditions for.
ESIMs in item 4 above incl band segmentation to ensure co existence between Land. ESIMs and Fixed services , Thoroughly examine the draft example WRC Resolution AI 1 5 and its annexes esp. the sections which are not yet agreed or discussed and propose a contribution for the. next CPM 19 2, Note that EACO was still considering this agenda item and did thus not have a common position . CEPT Preliminary Position, 2019 05 24 CEPT supports a regulatory framework for the operation of earth stations in motion ESIM in. the bands 17 7 19 7 GHz and 27 5 29 5 GHz while ensuring protection of and not imposing. undue constraints on services allocated in those frequency bands . Due to the foreseen growing demand for ESIM and because ESIM terminals are in motion and. world wide use the regulatory framework for these terminals needs to be as simple and. practicable as possible , Regarding the compatibility with terrestrial services in the 27 5 29 5 GHz bands CEPT supports. the following , Maritime ESIM minimum distance of 70 km from the low water mark officially.
recognized by coastal states and a maximum e i r p of 24 44 dBW 14 MHz towards the. territory of any coastal state similar to the method adopted in Resolution 902 WRC 03 . ESIM should comply with this minimum distance unless prior agreement of the. concerned administrations has been given , Aeronautical ESIM together with other technical conditions the pfd limits on the. earth s surface as specified in ECC Decision 13 01 should be used to ensure protection. of MS and FS This together with other consideration would ensure protection of. terrestrial systems ESIM should comply with these pfd limits unless prior agreement of. the concerned administrations has been given , Land ESIM operating within national boundaries no specific regulatory action or. amendments to the Radio Regulations at WRC 19 are needed . Regarding compatibility with terrestrial services in the 17 7 19 7 GHz band CEPT is of the view. that ESIM shall not claim protection from the fixed and mobile services in the band . CEPT is of the view that the pfd for Aeronautical ESIM and minimum distance for maritime. ESIM from the low water mark officially recognized by coastal states mentioned above are. sufficient for the protection of terrestrial services Therefore prior to authorising aeronautical. and maritime ESIM an administration is not required to perform coordination with regards to. terrestrial service stations of other administrations provided that the above mentioned pfd and. the minimum distance are met , CEPT is of the view that the pfd mask for Aeronautical ESIM and minimum distance for. maritime ESIM defined above are deemed to provide protection for the terrestrial services in. Agenda Item 1 5 Earth Stations in Motion at 17 7 19 7 GHz 27 5 29 5 GHz. order to provide regulatory certainty for both the terrestrial services and for the operation of. ESIM CEPT is not favourable to regulatory provisions that could allow protection requirements. other than pfd mask based on the need to protect future development of terrestrial services . Moreover CEPT is of the view that the proposed pfd mask shall be defined based on parameters. of terrestrial systems which are consistent with the technical characteristics provided by. responsible Working Parties at ITU R and should not address the protection of applications. which do not conform with these characteristics , Regarding compatibility with satellite networks the ESIM characteristics shall remain within the. envelope of the satellite network with which these ESIM communicate and the satellite network . when using ESIM shall not cause more interference and shall not claim more protection than. was coordinated when using typical earth stations in this satellite network . CEPT is of the view that in line with the principles already expressed in ITU Resolution 156. WRC 15 the notifying administration of the GSO FSS satellite network with which ESIM. communicate shall be responsible for ensuring that the ESIM network operator has the capability. to limit operations of ESIM to the territory or territories of administration having authorised. those ESIM and to comply with Article 18 and shall provide a point of contact for the purpose of. tracing any suspected cases of interference from earth stations in motion . In case of interference from L ESIM the administration of the territory on which the L ESIM. operates is responsible for authorising the operation of L ESIM on its territory and for acting In. case of interference from maritime or aeronautical ESIM the administration of the country in. which the ship or aircraft is registered and the administration responsible for the satellite network. should have joined responsibility to act to remove interference . CEPT has developed a Roadmap on 5G http www cept org ecc topics spectrum for wireless . broadband 5g roadmap In this respect it is noted that Europe has harmonised the 27 5 29 5. GHz band for broadband satellite and is supportive of the worldwide use of this band for ESIM . This band is therefore not available for 5G It should also be noted that in Europe according to. Decision ECC DEC 05 01 portions of the frequency band 27 5 29 5 GHz are designated and. can be used for the fixed service ,CITEL Draft Inter American Proposal.
2019 04 12 In accordance with Method B of the draft text for the Conference Preparatory Meeting it is. proposed that the addition of a new footnote to Article 5 of the Radio Regulations to include the. use of ESIMs in frequency bands 17 7 19 7 GHz and 27 5 29 5 GHz adopting a new Resolution. that contains the specific conditions for ESIM operation and ensures the protection of primary. services within them The attached Resolution would contain guidelines to help administrations. to authorize ESIMs in these bands ,RCC Preliminary Positions. 2018 03 15 1 The RCC Administrations support a draft new Resolution A15 WRC 19 which as a method. of addressing WRC 19 agenda item 1 5 shall contain technical conditions and regulatory. provisions with regard to operation of earth stations in motion ESIM communicating with. geostationary space stations in the fixed satellite service in radio frequency bands 17 7 19 7 GHz. space to Earth and 27 5 29 5 GHz Earth to space to provide protection based on existing. criteria of services having allocations in these and adjacent radio frequency bands including. EESS passive in the radio frequency band 18 6 18 8 GHz and future use of EESS Earth to . space in the radio frequency band 28 5 29 5 GHz and also use of terrestrial services in the radio. frequency bands 25 25 27 5 GHz and 27 5 29 5 GHz method in draft CPM Report . 2 The RCC Administrations consider that with regard to satellite networks or systems in space. services of other administrations in radio frequency bands 17 7 19 7 GHz and 27 5 29 5 GHz. ESIM shall comply with the following conditions , Agenda Item 1 5 Earth Stations in Motion at 17 7 19 7 GHz 27 5 29 5 GHz. a using ESIM within earlier registered frequency assignment to typical earth station of. GSO FSS satellite network the appropriate information on such a use shall be recorded in MIFR . If frequency assignment to a typical earth station was made under RR No 11 38 ESIM can use. this frequency assignment provided that ESIM shall not cause more interference nor claim more. protection than registered frequency assignment to the typical earth station If frequency. assignment to a typical earth station was made under RR No 11 41 ESIM shall not cause. unacceptable interference nor claim protection from interference with regard to recorded. frequency assignments that served the basis for the registration of frequency assignment to a. typical earth station under RR No 11 41 , b using ESIM within a new frequency assignment to GSO FSS satellite network requires. notifying administration to provide information to the Bureau according to RR Appendix 4 on. the characteristics of ESIM intended to communicate with the space station of this GSO FSS. network in order to be verified by the Bureau and to publish the results in specific section of BR. IFIC In this case such a frequency assignment to ESIM needs to be coordinated and registered . according to procedures of RR Articles 9 and 11 in the relevant GSO FSS satellite network before. starting the use of ESIM , c administration authorizing the use of ESIM in the territory under its jurisdiction is. entitled to request ESIM to use only those frequency assignments to GSO FSS network which. have been successfully coordinated notified implemented and recorded in the MIFR with a. favourable finding under RR Article 11 , 3 The RCC Administrations consider that with respect to terrestrial services operating in the radio.
frequency bands 17 7 19 7 GHz and 27 5 29 5 GHz ESIM shall comply with the following. conditions , a transmitting ESIMs in the frequency band 27 5 29 5 GHz shall not cause unacceptable. interference to stations of terrestrial services in this band operating in accordance with the Radio. Regulations or impose constraints on future development of these services . b receiving ESIMs in the radio frequency band 17 7 19 7 GHz shall not claim protection. from stations of terrestrial services in this band operating in accordance with the Radio. Regulations or impose constraints on future development of these services . c the notifying administration responsible for the GSO FSS satellite network with which. ESIMs communicate shall submit to the Bureau a commitment that in case of unacceptable. interference upon receipt of a report of such an interference will take appropriate action to. immediately cease or reduce the interference to the acceptable level . 4 The RCC Administrations consider that in the draft new Resolution A15 WRC 19 special. measures shall be envisaged to exclude unauthorized use of ESIM in the territory of States that. have not granted relevant authorizations licenses Regulations applicable to ESIM which would. be defined under the issue 9 1 7 of WRC 19 agenda item 9 1 shall be taken into account when. developing regulations within the frameworks of WRC 19 agenda item 1 5 . Agenda Item 1 6 Regulatory Framework for Non GSO FSS at 37 5 39 5 GHz 47 2 50 2 GHz . Agenda Item 1 6 Regulatory Framework for Non GSO FSS at 37 5 39 5 GHz 47 2 . 50 2 GHz , SFCG supports the revision of the current limits in Resolution 750 Rev WRC 15 for the band. 50 2 50 4 GHz to protect EESS passive for both NGSO and GSO systems taking into account. that studies have demonstrated the limits in Resolution 750 Rev WRC 15 do not sufficiently. protect passive services in the band Therefore SFCG supports Method D Option 1 of the draft. CPM text ITU R WP4A Chairman Report 4A 826 Annex 29 Studies have shown that. compatibility between EESS passive and NGSO FSS in the band 36 37 GHz is achieved noting. however that they did not address the cold calibration channel It is to be noted that sharing studies. for SRS and EESS earth stations in the bands 37 5 38 GHz and 40 40 5 GHz are not listed in. Resolution 159 WRC 15 These studies will have to be addressed by WP 7B through the revision. of Report ITU R SA 2307 and Recommendation ITU R SA 2079 for the band 37 5 38 GHz and. additional new report and recommendation for the band 40 40 5 GHz . APT Preliminary Position, 2019 08 06 APT Members support the establishment of regulatory and procedural conditions for non GSO. FSS satellite systems in the frequency bands 37 5 39 5 GHz space to Earth 39 5 42 5 GHz. space to Earth 47 2 50 2 GHz Earth to space and 50 4 51 4 GHz Earth to space while. ensuring protection to GSO satellite networks in FSS MSS and BSS and other existing primary. services in the same bands as well as protection of the EESS passive in the frequency bands. 36 37 GHz and 50 2 50 4 GHz and the radio astronomy in the frequency bands 42 5 43 5 GHz . 48 94 49 04 GHz and 51 4 54 25 GHz , APT Members support Method A of Issue 1 in the CPM Report . In the absence of suitable ITU R Recommendations able to be incorporated by reference APT. Members support consideration of Resolutions addressing . generic GSO Reference Links and calculation procedures that may be used to verify the. compliance of non GSO systems and, regulatory provisions to protect GSO satellite networks based on appropriate sharing.
methodology and reference characteristics of GSO satellite networks . APT Members support ensuring the protection of EESS passive from unwanted emission in. adjacent bands In relation to Issue 2 relating to possible modifications to Resolution 750 Rev . WRC 15 preference towards Option A has been expressed and Option B is still under. consideration,ASMG Preliminary Position , 2018 12 13 IssueA . Method B Carry forward the studies to ensure the protection of GSO satellite networks under. WRC 19 agenda item 1 6 to a new WRC 23 agenda item towards the development of epfd limits . Reason Resolution 159 WRC 15 indicates that technical and regulatory studies under this. agenda item shall focus exclusively on the development of equivalent power flux density limits. to protect GSO FSS satellite networks from non GSO FSS systems as appropriate . There are views that developing appropriate equivalent power flux density limits is still not. satisfied and if the relevant epfd limits are still not agreed upon in time for WRC 19 the studies. conducted to protect the GSO satellite network under this agenda item should be carried. forward to a new WRC 23 agenda item and should be modelled after Resolution 159 WRC 15 . Option A supported by ASMG , Agenda Item 1 6 Regulatory Framework for Non GSO FSS at 37 5 39 5 GHz 47 2 50 2 GHz . ATU Preliminary Position , 2018 09 17 Take Method A as the African preliminary position while continuing to further examine other. Methods and their implementation editor s note Method A presents a regulatory and technical. implantation to modify RR Article 22 to include a Regulatory framework to enable non GSO. systems based upon a maximum allowable percent increase in GSO unavailability specified in. the short term and long term performance objectives of the GSO links . Note that EXOWAS and EACO were yet to formulate a position on this agenda item and SADC. had no firm view yet , Note that the last WP4A meeting July 2018 proposed four methods to satisfy the agenda item . Methods A B and C are almost the same They only differ slightly on their implementation . Support the studies under Resolution 159 WRC 15 which aim at developing a regulatory. framework for new non GSO FSS satellite systems while protecting GSO FSS systems in the. frequency bands above 30GHz , Encourage administrations to contribute to ongoing studies and ensure protection of existing FSS.
GSO but also exploring opportunities that might come with new NGSO systems . CEPT Preliminary Position, 2019 05 24 CEPT supports the development of regulatory provisions technical and operational conditions. that would enable spectrally efficient operation of non GSO FSS satellite systems in the. frequency bands 37 5 42 5 GHz space to Earth 47 2 50 2 GHz Earth to space and 50 4 51 4. GHz Earth to space while ensuring protection for GSO satellite networks and stations of other. existing services including passive services in the adjacent frequency bands . CEPT considers that the limits currently in Resolution 750 Rev WRC 15 are not sufficient for. the protection of EESS passive in the adjacent frequency band 50 2 50 4 GHz from operation. of both GSO and non GSO FSS satellite systems in the frequency bands under consideration in. accordance with Resolution 159 WRC 15 Appropriate unwanted emission limits for the. protection of EESS passive are 51 3 dBW 200 MHz for non GSO user terminals 48 7. dBW 200 MHz for non GSO gateways 58 1 dBW 200 MHz for GSO user terminals and 44 1. dBW 200 MHz for GSO gateways , CEPT supports the development of the new Recommendation ITU R S 50 40 GHz Sharing. Methodology which describes in particular the methodology to calculate the maximum. permissible level of interference from non GSO satellite systems specified as single entry and. aggregate limits for a increase in unavailability time allowance for degradation of GSO. networks short term performance objectives b a maximum reduction of the throughput or. spectral efficiency for GSO networks using Adaptive Coding Modulation CEPT supports that. this methodology takes into account the correlation between a fading event attenuating both the. wanted signal and interfering signals in the frequency bands 40 50 GHz In addition CEPT. supports that the conformity with these single entry limits be evaluated using the calculation. procedures in the new Recommendation ITU R S 50 40 GHz Sharing Methodology and using. the statistics of degradations due to the non GSO system interference and fading issued from the. latest versions of Recommendations ITU R S 1503 and P 618 respectively . CEPT also supports the development of the new Recommendation incorporated by reference. ITU R S 50 40 GHz Reference links which contains characteristics of representative FSS GSO. reference links ,CITEL Draft Inter American Proposal. 2019 04 12 The use of the frequency bands 37 5 39 5 GHz space to Earth 39 5 42 5 GHz. space to Earth 47 2 50 2 GHz Earth to space and 50 4 51 4 GHz Earth to space by a non . GSO satellite system in the fixed satellite service or mobile satellite service is subject to the. application of the provisions of No 9 12 for coordination with other non GSO satellite systems. Agenda Item 1 6 Regulatory Framework for Non GSO FSS at 37 5 39 5 GHz 47 2 50 2 GHz . in the fixed satellite service and or non GSO satellite systems in the mobile satellite service but. not with non GSO systems in other services , In the frequency bands 1 350 1 400 MHz 1 427 1 452 MHz 22 55 23 55 GHz 30 31 3 GHz . 49 7 50 2 GHz 50 4 50 9 GHz 51 4 52 6 GHz 81 86 GHz and 92 94 GHz Resolution 750. Rev WRC 19 applies ,RCC Preliminary Positions, 2019 01 25 The RCC Administrations consider that studies on technical and operational issues and.
regulatory provisions in order to ensure operation of non GSO FSS satellite systems in the. frequency bands 37 5 42 5 GHz space to Earth 47 2 48 9 GHz limited to feeder links 48 9 . 50 2 GHz Earth to space and 50 4 51 4 GHz Earth to space shall ensure protection to GSO. satellite networks in FSS MSS and BSS and also to stations of other existing services in the. same and adjacent frequency bands , The RCC Administrations consider that technical conditions and regulatory provisions shall be. developed to ensure sharing of the considered frequency bands between non GSO FSS systems . The RCC Administrations support the revision of Resolution 750 Rev WRC 15 and. establishment of appropriate unwanted emission limits for non GSO FSS earth stations operated. in the frequency bands 49 7 50 2 GHz and 50 4 50 9 GHz to protect EESS passive in the. frequency band 50 2 50 4 GHz taking into account aggregate interference effect caused by. existing radio services systems in adjacent frequency bands The RCC Administrations consider. that Article 22 of the Radio Regulations shall establish the limitations for non GSO FSS systems. in order to ensure proper protection of GSO FSS and BSS systems in the frequency bands. concerned To identify the limits mentioned the RCC Administrations support the development. of new Recommendation ITU R S Methodology to assess FSS compatibility in the 50 40 GHz. bands for establishment of the appropriate protection criteria and maximum permissible levels. of interferences from non GSO FSS systems to GSO FSS networks in 40 50 GHz bands as well. as new Recommendation ITU R on characteristics of GSO FSS and BSS reference links in 50 40.
