基于单星测轨进行LEO和GEO目标编目

针对既有天基探测的不足,本着降低卫星制造难度、使用复杂度,拓展监视对象的原则,针对编目测轨所需,论证设计了一个采用零倾角、9 000km高度轨道,装有7个可见光探测器,以空域监视方式支持空间目标编目测轨的构想。该构想只需1颗卫星,即可形成空间目标编目所需的测轨,独立支持LEO（低地球轨道）和GEO（地球同步轨道）目标的编目管理,具有战略、战术双重价值。

Cataloging LEO and GEO Objects Based on Metric Data Collected by a Single Satellite

Space-based surveillance has the advantage of high coverage and short time interval because it is beyond the limits of land,territory and weather.A self-contained space-based surveillance can not only improve the precision of space object orbits,but also support the catalog of important objects independently in the case of collapse of ground sensors.Therefore,it has high strategic and tactical value.To make up for the shortage of existing space-surveillance systems and to meet the requirements of self-contained space-based surveillance,this paper presents a space-based surveillance design at an altitude of about 9 000 km,zero degree inclination and with seven visible spectrum sensors.Simulation shows that it can be self-contained to support catalog of LEO and GEO objects even with a single satellite.
