| Summary: | Aiming at the simulation analysis scenarios of frequency compatibility between NGSO constellation system and GSO satellite system in the Ka uplink and Ku downlink frequency band, one tracking mode of the earth station of NGSO constellation was proposed.By calculation results analysis, the quantitative infl uence was depicted in common tracking mode of the earth station, such as ephemeris guided tracking, single pulse automatic tracking, and sidelobe tracking.And taking the parameters registered on ITU of Telesat and CHNSAT-98E systems as an example, the simulation data was compared and analyzed in diff erent tracking modes of the earth station.Then, one available tracking strategy of the NGSO constellation station was proposed, which is under the constraint of recommendation ITU-R S.1323.The research results can be used as a reference for NGSO-GSO system compatibility analysis, also the tracking plan formulation of earth stations. |
