摘 要:
轨控发动机对空间飞行器姿态的干扰力矩是影响姿态估计精度的重要因素，为了解决轨控发动机干扰力矩在地面难以准确测量的问题，提出了一种在空中进行的轨控发动机干扰力矩测试方法。此方法通过在空间飞行器飞行过程中轨控发动机轮流开机，利用惯测组合陀螺记录弹体姿态角速度的变化情况，从而计算出轨控发动机的干扰力矩。数值仿真结果验证了该试验方法的有效性。[著者文摘]

Abstract:
The disturbing torques of the divert thrusters are the main factors affecting attitude estimation of the spacecraft. In order to solve the problems that the disturbing torques could not be measured on the ground, a method of testing the torques in space is designed. In the test, the divert thrusters are planned to be on by turns in space and the torques could be evaluated by the angular rate measurement values. The result of the simulation demonstrates the feasibility of the method.[著者文摘]
