摘要
结合激光星间链路的技术特点和卫星偏航姿态对激光链路指向的影响,推导了基于导航星历的坐标旋转算法,优化了卫星偏航姿态的控制策略。通过建立导航卫星平台、激光终端捕获跟踪性能以及轨道动力学等可视性约束条件模型,计算出各卫星在目标时段内的可视情况。
A coordinate rotation algorithm based on navigation ephemeris is introduced according to the technical characteristics of inter-satellite laser links.A control strategy of satellite yaw attitude is also optimized considered its effect on laser link direction.Then,a constraint condition model of visibility is set up considering three constraints：the satellite platform,the performance of laser terminal and the orbit dynamics to calculate the visibility status in target period of each satellite.
