一、电池阵定向控制的必要性及控制方法的概述随着大型地球观测卫星的观测手段多样化,旋转执行机构的采用以及轨道观测寿命的增长,对星载电源容量的要求越来越大,传统的银锌电池已很难满足卫星供电要求.于是,不但通信卫星,而且长寿命地球观测卫星也出现了采用太阳电池供电的趋势.为充分发挥供电效率,须考虑电池阵对日定向控制问题.对地球观测卫星来说,大致有两种可供选择的定向
I. Overview of the Necessity of Battery Array Direction Control and Control Methods With the diversification of observation means of large-scale Earth observation satellites, the adoption of rotary actuators and the growth of orbital observation life, the requirements on the on-board power supply are becoming larger and larger, Traditional silver-zinc batteries have been difficult to meet the satellite power requirements, so not only communication satellites, but also long-life earth observation satellites also appeared the trend of using solar cells.In order to give full play to the power supply efficiency, we must consider the battery array orientation control problems For Earth observation satellites, there are roughly two alternative orientations
