用GPS观测量确定像地球同步转移轨道(GTO)这类大椭圆轨道的用户卫星轨道和姿态在许多方面具有明显的优越性。例如对于航天器来说,敏感器可以减轻重量,缩小体积,降低功耗。从卫星测控方面来说,可以减少跟踪和测控任务的工作量,因而能降低运营成本。除了这些,也能提高发射和早期轨道阶段(LEOP)的遥控能力。 Using GPS observations to determine satellite orbits and postures of users of large elliptical orbits such as the geostationary transfer orbit (GTO) has significant advantages in many ways. For example, spacecraft, the sensor can reduce weight, reduce size, reduce power consumption. In terms of satellite measurement and control, it can reduce the workload of tracking and monitoring tasks, thus reducing operating costs. In addition to these, remote control of launch and early orbit phases (LEOPs) can also be enhanced.
