SHARING IN THE 1-3 GHz FREQUENCY RANGE BETWEEN NON-GEOSTATIONARY SPACE STATIONS OPERATING IN THE MOBILE-SATELLITE SERVICE AND STATIONS IN THE FIXED SERVICE
Levels of power flux-density (pfd) and fractional degradation in performance are presented as thresholds for coordination of frequency assignments for non-geostationary orbit (non-GSO) space station transmitters in the mobile-satellite service MSS and receiving stations in the fixed service (FS) in frequency bands shared between these services in the 1-3 GHz frequency range. In the annexes, the...
متن کاملResource Allocation for Cognitive Satellite Uplink and Fixed-Service Terrestrial Coexistence in Ka-Band
This paper addresses the cognitive Geostationary Orbit (GSO) satellite uplink where satellite terminals reuse frequency bands of FixedService (FS) terrestrial microwave links which are the incumbent users in the Ka 27.5-29.5 GHz band. In the scenario considered herein, the transmitted power of the cognitive satellite user has to ensure that the interference impact on potentially present FS link...
متن کاملDoppler Effect in Non-gso Satellite Propagation
Recent technological advances have accelerated a renaissance in usage of non-geostationary (non-GSO) communication satellites in provision of various services domestically and globally. Early ventures into communication satellites have used satellites in low Earth orbits. The main reasons for this mode of operation were that the booster technology was not available to lift satellites into a hig...
متن کاملInterference Potential of FSS and BWA on the Extended C-Band
The Indonesian government has allocated the 3.3-3.4 GHz band, which is adjacent to the extended Cband 3.4-3.7 GHz, for Broadband Wireless Access (BWA) services. The country has been using the extended C-band for Fixed Satellite Service (FSS). This research shows the interference potential between the two systems if an adjacent band is allocated for them. Using a clutter loss of 10 dB and site s...
متن کاملRECOMMENDATION ITU-R SF.1601-2 Methodologies for interference evaluation from the downlink of the fixed service using high altitude platform stations to the uplink of the fixed-satellite service using the geostationary satellites within the band 27.5-28.35 GHz
This Recommendation provides methodologies for the interference evaluation from the HAPS-to-ground transmission downlink of the fixed service (FS) using high altitude platform stations to the uplink of the fixed-satellite service using the geostationary satellites within the bands 27.5-28.35 GHz.This Recommendation contains three Annexes that provide methodologies for interference calculation, ...
