本文介绍了航天飞机上使用的星光跟踪器的工作特性、技术条件、硬/软件系统的作用及星光跟踪器的仿真方法和误差模型。由于观察者(宇航员)的速度和星体的光速之间有偏差,所以必须考虑天体光行差的影响,文中有简单的描述。星光跟踪器也可为飞行器交会服务。本文对了解美国航天飞机的控制系统部分和确定我国航天运输系统的方案无疑是有益的。
This article describes the operating characteristics, technical conditions, the role of hardware / software systems and the star tracker simulation method and error model of the star tracker used on the space shuttle. Due to the deviation between the speed of the observer (astronaut) and the speed of light of the celestial body, the influence of the optical aberration of the celestial body must be taken into account. A brief description is given in the text. Starlight trackers can also be rendezvous for aircraft. This article is undoubtedly beneficial to understand the part of the control system of the U.S. space shuttle and to determine the program of China’s space transportation system.
