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 means of on-orbit monitoring of spacecraft. As the task form gets more and more complicated, more and more on-orbit of spacecraft are in operation, and conventional information telemetering methods can not meet the requirements. In view of this problem, this paper presents a visual telemetry method, which uses the on-orbit of the camera to directly monitor the course of the spacecraft’s movements and obtains the key information such as the velocity and displacement of the spacecraft’s motion through the analysis and calculation. Back to the aircraft in-orbit verification, proved the effectiveness of the method.
