Analysis of Realization of Station Pointing Attitude for KX-02 Satellite

摘要: 空间飞行器采用特定的飞行姿态,使飞行器上的载荷精确探测感兴趣的地区或目标,实现目标信息提取的飞行任务。文中提出了对地面站指向模式下的两种实现方案,同时对多个相关状态转换矩阵的影响量级进行了评估分析。以两种指向实现方案互为备份,将大大提高飞行器姿控系统对站指向的可靠度,确保姿态指向模式的可靠而有效地实现。

Abstract: Spacecrafts usually keep a certain attitude in order that the payload onboard the S／C can remotely sense the targets of interest, and successfully get the interesting information about the targets during the flight mission. Two methods for realization of station pointing attitude are put forward. Therein, the influences of transformation matrices of different coordinate system on position of S／C are assessed. With these two methods fulfilled in S／C simultaneously, the station pointing attitude can be reliably and effectively realized.
