" last , 4he method of measuring smp using ground transponder is discussed . the measuring model and mathematics model of this method is desired . the algorithm is derived
给出了基于有源转发器方法测量卫星运动参数的测量模型和数学模型，在此基础上，推导了确定卫星位置的算法。
Secondly , for satellite controlled by reaction wheels , an algorithm or strategy is presented . and then reaction wheels are used to generate a known disturbance torque , using thrusters as controller and gyro as the attitude sensor , a thruster parameters calibration for thruster levels and alignments on - line is achieved
其次,针对反作用飞轮控制的卫星,提出了一种卫星质量特性在线辨识策略和辨识算法,并利用反作用飞轮产生扰动力矩,推力器作为控制执行机构,使用陀螺测量卫星姿态角速度,实现推力器推力大小和方向等参数的在线辨识。
