摘要
文章通过用户星地固系位置、速度数据和GEO卫星6根轨道参数,在星载控制器上计算用户星GEO终端天线的指向角度。该算法已在星上成功应用,指向精度和运算速度满足星上使用要求。
The algorithm to compute GEO terminal antenna pointing angle on onboard satellite controller is discussed in this paper,with help of user satellite Earth Center Fixed(ECF) position velocity data and GEO orbit parameters.This algorithm has been successfully applied on satellite.The pointing precision and operation velocity can meet the needs of application on satellite.
