航天器动作状态的可视化遥测方法研究

Research on Visual Telemetry Method for Spacecraft Motion Status

遥测是航天器在轨状态监控的重要手段,随着任务形式逐渐复杂,航天器在轨动作也越来越多,常规的信息遥测手段难以满足要求。针对该问题,本文提出一种可视化遥测方法,使用相机在轨拍摄图像对航天器动作过程进行直观监测,并通过分析计算,获得航天器动作的速度、位移等关键信息,通过月地高速再入返回飞行器在轨验证,证明了该方法的有效性。

Telemetry is an important method for monitoring the status of the spacecraft on orbit. With the increasing complexity of the mission, more complex in-orbit motions of the spacecraft need to be achieved, but the conventional telemetry means can hardly meet the requirements. In this pa-per, a visual telemetry method was proposed. Images taken by orbit camera were used to monitor the spacecraft motion visually, and the spacecraft＇s velocity, displacement, and other key information were obtained through analysis and calculation. The flight results of circumlunar return and reentry spacecraft of the 3rd phase of China Lunar Exploration Program proved the validity of this method.
