GPS技术是航天工程中具有发展前途的关键技术，是卫星自主定姿定轨高效经济的方法。新一代大型静止轨道卫星（即地球同步轨道静止卫星）上采用GPS自主定姿定轨技术能使卫星定姿定轨技术上一个新台阶。本文着重分析研究了新一代大型静止轨道卫星平台上采用GPS自主定姿定轨技术的可行性。 GPS technology is the key technology with the promising development in aerospace engineering, and it is the efficient and economical method of determining the orbit of satellite autonomously. A new generation of large geostationary orbit satellites (ie, geostationary orbit geostationary orbit) using GPS self-aligning orbit determination technology can make the satellite orbit and orbit technology to a new level. This paper focuses on the analysis of a new generation of large geostationary orbit satellite platform using GPS self-orientation orbit determination technology feasibility.
