第五届中国卫星导航学术年会电子文集 The Analysis of GPS Constellation Deployment and Maintenance Strategy Xin Liu1, Wenhai Jiao1,2 1. Test and Assessment Research Center. China Satellite Navigation Office, Beijing 2. Beijing Institute of Tracking and Telecommunication Technology ，Beijing 1. jmdliuxin@ Abstract: By far, GPS constellation is the most successful one of GNSS in operational. So it will benefit from studying the strategy of GPS phased deployment and maintenance for those countries which want to build their own satellite navigation system. This paper outlined evolutionary history of GPS satellites, described GPS constellation and its deployment phases, analyzed GPS constellation configuration in each deployment phase, summarized GPS constellation deployment and maintenance strategy, and made recommendations for BeiDou System’s deployment and maintenance. Keywords: GPS satellite; constellation configuration; phased deployment; BeiDou System; maintenance strategy.
