摘　　要：就目前靶场弹道测量手段存在的不足 ,通过对GPS相位平滑伪距差分和载波相位差分技术的分析 ,提出用GPS差分技术与测控设备进行一体化设计 ,实现靶场弹道高精度的测量。文中给出了该方案的实施原理图和软件流程图。通过与靶场现有的测量方法相比较表明 ,所提出的方法不仅能够提高精度 ,克服目前靶场测量方法的不足 ;而且可以极大地改善靶场的测量环境 ,填补靶场空白。At the present time,being the shortage of measurement in the proving ground,a system incorporating the technology of the differential GPS pseudo distance and the differential real time kinematic (RTK) into the observing and control equipment is designed,which can achieve the high precision measure of trajectory in the proving ground.The schematic diagram and the flow of software of this system are given.The comparisons with the existing measurement of the proving ground show that the method not only gets over the shortage of measurement of proving ground now but also gives higher measure precision than the existing observing and control equipment.With achievement of this measurement in the proving ground trial,it can improve the measure environment of proving ground greatly and fill the blank of proving ground trial.This resolution,of course,is worth of extending and using for reference.
