摘要
文中对基于角度量观测的卫星初轨计算技术进行了研究。当具有单圈观测弧段时,提出一种新的初轨计算方法—图解法;当观测弧段较短时,采用遗传算法确定初始轨道,并设计了一种收敛速度快、寻优精度高、便于工程化的十进制浮点数编码遗传算法。通过仿真计算验证了提出方法的有效性。
In this paper,initial orbit determination for satellites based on angle measurements is studied.When having one circle of angle observing data,a new method of initial orbit calculation for satellites-diagram approach is presentsd.When only having short-arc angle measurements,the Genetic Algorithm(GA)is used for the computation. And an Algorism Float-Coded Genetic Algorithm (AFCGA) is designed,which have high convergence speed,high optimization accuracy and simple realization.In the end,simulation results show the validity of both diagram approach and AFCGA.
