Agenda Item Description
Agenda 1.8.1 Definition of out of band and spurious emissions
Agenda 1.8.2 Protection of passive services from out of band emissions
Agenda 1.13 Use of the bands 47.2 - 47.5 GHz and 47.9 - 48.2 GHz by HAPS and potential use of bands between 18 - 32 GHz by HAPS in the FS including: 1) analyse cases where deployment of HAPS over one administration affects others, 2) continue to study sharing between HAPS and other services such as FS, RA, 3) study sharing with other services to identify 2 * 300 MHz paired bands in the range 18 - 30 GHz
Agenda 1.18 Primary allocation in Region 1 for FS in band 17.3 - 17.7 GHz
Agenda 1.19 Study the criteria and process for the resolution of possible cases of misappplication of non-GSO FSS single entry limits under S22
Agenda 1.24 Review of sharing conditions between services in the band 13.75 - 14 GHz band
Agenda 1.25 Consideration of possible bands to be identified for high density FSS usage in bands above 17.3, in particular above 19.7 GHz
Agenda 1.27 Application and study of the regulatory procedures and assocated sharing criteria contained in Appendices S30 and S30A and associated provisions in Articles S9 and S100 as revised by WRC 2000
Agenda 1.27 Sharing procedures and criteria between RX ES in BSS and TX ES in the FSS or FS TX Stations in the relevant BSS, FSS or FS bands
Agenda 1.29 Frequency sharing in the range 37.5 - 50.2 GHz between GSO FSS networks and non-GSO FSS systems
Agenda 1.29 Development of procedures in case the operational or additional operational limits in S22 are exceeded
Agenda 1.30 Consider possible changes to the produces for the advanced publication, coordination and notification of satellite networks.
Agenda 1.31 Sharing studies for possible MSS allocations in the 1-3 GHz band including 1518 - 1525 MHz, 1) taking into account Rec. 1459, 2) reviewing the PFD levels to use as coordination trigger to protect P-MP FS systems, 3) if sharing is unsatisfactory then to consider alternative bands in the 1-3 GHz range
Agenda 1.31 Sharing studies for possible MSS allocation in the 1-3 GHz range including the band 1683 - 1690 MHz including 1) determining approprate separation distances between MES and MetSat stations, 2) assess the current and future requirements for spectrum for MetAids, 3) if sharing unsatisfactory then consider alternative bands in the 1-3 GHz range.
Agenda 1.32 Protection of the radio astronomy service in the 42.5-43.5 GHz band, including 1) study of the provisional PFD limits given in S5, 2) identify technical and operational limits including mitigation techniques that could be used to protect RA stations from BSS and FSS space stations
Agenda 1.32 PFD limits in the bands 37.5 - 42.5 GHz for the FSS, BSS and FSS services, including 1) determing whether the PFD limits protect the FS in the bands 37.5 - 40 GHz and 42 - 42.5 GHz from FSS and MSS s-E transmissions, 2) determining whether the PFD limits protect the FS in the band 40.5 - 42 GHz from FSS, 3) study technical and operational characteristics and PFD values for BSS in range 40.5 - 42.5 GHz, 4) taking into account proper balance between various services, 5) studying mitigation techniques but taking account of impact on these systems, 6) analysing sharing between FS into FSS ES in HD FSS applications in the bands 39.5 - 40 GHz and 40.5 - 42 GHz in the same geographic area, 7) in the bands 37.5 - 40 GHz and 42 - 42.5 GHz study clear air PFD levels and % time they could be exceeded to overcome fading of satellite downlink in way that protects FS
Agenda 1.34 Use of the band 2630 - 2655 MHz in certain Region 3 countries by non-GSO satellite systems in the BSS (sound), including 1) calculation methodologies and sharing criteria, and 2) sharing studies between BSS (sound) and terrestrial services
Agenda 1.37 To consider the regulatory and technical provisions for highly elliptical orbits
[Resolution 139] Study the technical, operational and regulatory aspects of the current and expected future use of FSS allocations for DTH TV broadcasting
[Resolution 76] Protection of GSO FSS and BSS networks from aggregate EPFD produced by multiple non-GSO FSS systems including 1) methodology for calculating aggregate EPFD, 2) accurate modelling of interference from non-GSO into GSO networks, 3) procedures to be used by non-GSO operators when the aggregate EPFD limits are exceeded, 4) measures to identify the interference levels from non-GSO systems in excess of the aggregate limits.
[Resolution 137] Further studies of the sharing conditions between GSO networks and non-GSO systems in the FSS to 1) develop methodologies to assess the operational and additional operational EPFD levels that may used to compare against the relevant limits, 2) develop data formats that can be used to describe the non-GSO systems in sufficient detail for assessments of the operational and additional operational limits, 3) develop methodologies for generation of continuous EPFD vs % time curves for other GSO ES antenna diameters than those in the limit tables, 4) develop methodologies for generation of continuous EPFD vs % time curves for GSO satellite beamwidths other than those in the limit tables, 5) study the sharing criteria that may be applied during coordination between non-GSO FSS systems
