摘要
针对采用WGS 84椭球模型的三星座测时差定位算法 ,分别对高程假设引起的系统误差和随机测量误差引起的定位精度分布进行了分析 ,给出了仿真结果。研究表明 ,该定位方法可以实现高定位精度 ,适合对接近大地水准面的目标定位。
the location method based on WGS 84 ellipsoid model using satellites DTOA measurements is discussed, and location precision caused by target height assumption and random measure error are analyzed with simulation results presented later. The research shows that this method can achieve high precision and is reasonable for near-zero height target location.
