摘　　要：多站时差定位测量系统具有发现距离远、适用信号种类多、隐蔽性强、测量精度高等优点,传统布站需要综合考虑目标进入方向、高度、接收遥测信号等因素,本文通过GDOP仿真评估分析,提出综合布站方案及空中、地面立体改进方案,保证无论目标从什么方位进入待测量区域,定位精度均能满足测量要求,对高速飞行器低高度段轨道测量和落点测量具有参考意义。In view of the high speed flight vehicle passive accurate positioning problem,time difference location measurement system has found more distance,suitable types of signals,high accuracy,strong concealment,etc.The traditional cloth station needs to consider the target into the direction,factors,such as height,receiving telesignaling signals by analyzing GDOP simulation evaluation.This paper put forward comprehensive cloth station plan,and air and ground solid improvement guarantee from the goal no matter what position into the measurement area,position precision can satisfy the measurement area and the measurement requirements.The high speed flight vehicle low altitude section of track and point measurement has certain reference significance.
