摘　　要：介绍了一套基于扩频伪码单程测距、多基站时差定位、GPS同源共视定时的外弹道测量系统,给出了该系统的设备组成、工作原理,分析了系统工程实现中的几个关键技术问题及其解决途径,分析了影响系统定位精度的关键因素,给出了系统的理论定位精度。该系统具有外测精度高、抗干扰、保密强、可以适用于多目标测量等优点。A scheme of exterior ballistic measurement system is put forward based on the techniques of taking spread spectrum PN code as one-way ranging signals, locating target with time differences between two stations, and timing 4 ground stations through a single satellite. The principle and constitutes of the system are provided in the paper and several critical technologies and their solutions in engineering are analyzed. By analyzing the key factors that have influence on the system locating accuracy, the theoretical location accuracy of the system is presented. The system has the characteristics of high accuracy, high security, is suitable for multi-target telemetry and with anti-jamming capability.
