摘　　要：为满足靶场航落区外弹道测试以及关键段测试需求,利用弹载GPS/BD导航信息误差固定、不会随时间累加的特点,结合遥测地面站波速角宽的测试优势,提出一种利用遥测GPS/BD定位数据实时引导雷达局部组网技术;该方法首先对遥测地面站接收到的GPS/BD数据进行实时解算、坐标转换;然后通过指控网络将引导数据实时发送至雷达,实现遥测引导雷达;为保证整个传输过程数据可靠稳定,通过添加校验后再传输的方法,提高传输数据质量;通过实际应用,该方法可以稳定可靠的引导雷达完成测试任务。In the range test,the traditional single reference station has limited its range due to the limitation of the baseline length,and the difference accuracy is obviously affected by the decrease of the atmospheric error after a certain distance.In order to solve the problem that the GPS single frequency pseudorange differential positioning accuracy decreased resulted from far distance,a multi-base station GPS positioning pseudorange differential location method is proposed.This method analyzes the relationship between pseudorange equation and pseudorange differential location in depth;establishes a range base station to receive real-time target data and base station positioning data and transmits it to the control center.In order to solve the target location information in real time,this method designs multi-base station data processing algorithm and multi-baseline measurement data weighted processing method,which uses distance difference based linearity difference model.The test results show that the multi-base station GPS positioning pseudorange differential positioning method can effectively solve the problem that the precision of single-base pseudorange differential positioning decreases with the increase of the distance between the subscriber station and the base station,and improves the test precision.
