摘　　要：采用ＧＰＳ定姿技术作为卫星高精度自主姿态确定系统的备份，可以提高系统可靠性。在小型和微小卫星上采用ＧＰＳ定姿技术，保证在满足重量、功耗和其它技术指标的条件下，姿态和轨道控制系统全面满足任务要求。本方案为探索当今姿态和轨道控制系统基本型的研究迈出了一步。In this paper, the GPS based attitude determination is conbined into the on-board high accuracy autonomous attitude determination system as a backup to enhance the system reliability. In small satellite mission, the attitude and orbit control system aided with GPS based attitude determination can be able to fully meet the mission requirements subject to system's mass, power and other specifications. This concept made a big step forward to research the basic model of current attitude and orbit control system for today spacecrafts.
