摘要

针对NGSO星座系统在上行Ka频段和下行Ku频段对GSO卫星系统之间的频率兼容性仿真分析场景，在对地球站的常用跟踪模式对频率兼容性计算结果的影响程度进行定量化分析的基础上，提出一种基于频率兼容性评估的NGSO-GSO地球站跟踪模式分析方法。以ITU实际登记的Telesat和CHNSAT-98E卫星网络资料为例，对上下行通信链路在地球站不同跟踪模式下的频率兼容性仿真数据进行比对分析，提出一种在满足ITU-R S.1323建议书集总干扰保护标准的前提下，地球站可用跟踪策略的建议。研究成果可作为NGSO-GSO间系统兼容性分析及地球站跟踪计划制定的借鉴。

Abstract

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.
