Design of a high-precision exterior ballistic measurement system

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.
