摘要
针对"北斗"定位系统和海上天文定位存在的缺陷,提出舰船在海上利用北斗卫星和天文船位线进行联合定位的方法,重点讨论了两颗北斗卫星和一条天文船位线联合定位方程的求解,并对定位结果进行了仿真分析,表明方案可行,精度也完全满足海上舰船定位的要求。
Aim at the shortcoming of ＂BeiDou＂ position system and the issue of celestial navigation, this paper puts forward a method to fix with BeiDou Satellites and Astronomical Line of Position on the sea. Stressing the equation solution to location with two BeiDou satellites and one Asmmomical Line of Position, the simulation results show the method is feasible and the precision is accord with the require for warship to position on the sea.
