摘要

我们考虑了一颗机动陆地测量卫星，该卫星具有数字姿态控制系统，该系统由天文校正的捷联惯性导航系统、一组四个反作用轮和一个磁驱动器组成。光电变换器的矩阵在对地表部分进行光电观测时，以时间延迟和积分的方式工作，通过一组路径对地表部分进行扫描。研究了扫描式陆测航路和航天器旋转机动的矢量样条姿态制导律的解析综合问题，以及实现该制导律的卫星经济姿态控制律的综合问题。

Guidance and economical digital attitude control of a land-survey satellite

We consider a maneuvering land-survey satellite with a digital attitude control system equipped by a strapdown inertial navigation system with astronomical correction, a cluster of four reaction wheels and a magnetic driver. The matrices of optoelectronic converters work in the mode of time delay and integration during optoelectronic observation of the Earth surface parts by a set of routes for their scanning. We study the problems on analytical synthesis of the vector spline attitude guidance laws for the scanning land-survey routes and the spacecraft rotational maneuvers, and also the problems on synthesis of the satellite economical attitude control laws for fulfillment of the guidance laws.
