差分GPS外弹道测量系统的设计与实现

Design and Implement of DGPS to Trajectory Measure System in the Proving Ground

通过对目前靶场外弹道测量手段存在不足的分析 ,提出用GPS伪距差分和载波相位差分技术与测控设备进行一体化设计的方案 ,实现了靶场外弹道高精度的测量。给出了该方案实施原理图和软件流程图 ,并给出数据处理结果实例 ,证明该方案不仅测量精度提高 ,而且可以极大的改善靶场的测量环境 。

At present, being the absence of measure methods in the proving ground, we design one system with the application of the technology of the differential GPS pseudo distance and the differential real time kinematic(RTK) to the measure and control equipment. So that we can realize the high precision measurement of outer-trajectory in the proving ground. Then, give the principle and the flow of software of this system .To analyse the result of data processing and comparisons the result to the existing measurement method of the proving ground show that the proposed method is not only increasing precision but also improving the measurement environment of proving ground greatly. This measure method and technology project ,of course, are worth of extending and using for reference.
