摘要
关于航天器测轨问题 ,由天基网部分地代替地基网是目前航天测控的一个发展趋势 ,现已实现的利用全球导航系统 (GPS)和跟踪与数据中继卫星系统 (TDRSS)对低轨用户星的测轨手段就是如此。本文将阐述另一种类型的测轨模型和具体定轨方法 ,即一个中低轨卫星星座中的卫星与地面站的组合对星座中其它卫星进行定轨。
The space based net partially replaces the ground based net is one of the current tendencies in the spacecraft tracking and control, such as Global Position System(GPS) and the Tracking and Data Relay Satellite System(TDRSS) being used to tracking the low altitude user spacecraft. In this paper, we specify another model of the satellite tracking and its method for the orbit determination. Therefore, we combine the tracking data of one spacecraft in the medium altitude of low altitude satellite constellation from the ground based stations and the tracking data of another spacecraft in the same constellation from this ‘tracking’ satellite to determine their orbits simultaneously.
