The invention provides a satellite attitude determination and control system, which comprises: a command processing module, and an attitude determination module, an attitude control module and an information storage module which are connected to the command processing module. Specifically, the command processing module is used for receiving, explaining, judging and executing a control instructionfrom a ground station or a satellite keeping system; the attitude determination module is used for calculating current attitude information of the satellite according to measurement data acquired by an attitude sensitive device in a preset control stage; the attitude control module is used for acquiring the attitude information determined by the attitude determination module, performing calculation according to a control law corresponding to a preset control stage and on the basis of the attitude information, generating a control command of an attitude control actuator, and driving the attitude control actuator to execute the control command; and the information storage module is used for storing the information of the attitude sensitive device and the information of the attitude control actuator, forming a whole-track data packet by the stored information and transmitting the whole-track data packet to a ground station. According to the invention, attitude control requirements of eachstage of the satellite are met.

    本申请提出一种卫星姿态控制系统,包括:命令处理模块、与所述命令处理模块连接的姿态确定模块、姿态控制模块和信息存储模块,其中,命令处理模块用于接收、解释、判别并执行来自地面站或星务管理系统的控制指令;姿态确定模块用于在预设控制阶段,根据姿态敏感器件采集的测量数据,计算卫星当前的姿态信息,姿态控制模块获取姿态确定模块确定的姿态信息,并根据姿态信息,按照预设控制阶段对应的控制律进行计算,生成姿控执行器的控制命令,并驱动姿控执行器执行控制命令;信息存储模块用于存储姿态敏感器件的信息和姿控执行器的信息,将存储的信息组成整轨数据包传送给地面站。通过本申请,满足了卫星各阶段的姿态控制需求。
