摘　　要：在推导三站无源定位解的基础上,研究了对空定位和对地定位的精度影响因素,仿真结果表明对空定位精度在目标高度为0时对地定位精度一致。建立了一定空间区域的精度等效推算试验方法模型,并分析了高度引起的误差、站址误差、量测误差分别对时差无源定位系统定位精度的影响,实现了根据少数测试精度数据推算出一定空间区域的定位精度。Factors affected location precision to air and to ground are researched based on deducing 3 stations location result, simulation result shows precision to ground is equivalent with precision to air when its height is O. Then the model of equivalent calculating method is built and affection of error arouse by height, stations address, measure to time different passive location system are analyzed, precision in cer- tain area can calculate according to some measure data.
