GPS遥测编码电路设计

针对采用全球定位系统(GPS)/遥测技术(TM)研制的在研武器增程炮弹、火箭弹弹道轨迹测试、无人机航迹测试中弹载GPS定位信息及其它被测物理量测量信息实时融合、编码、遥测转发传输等任务要求,提出一种弹载GPS遥测编码电路设计的新方法。该方法通过双CPU控制、双端口缓冲存储实现弹载可编程装定、被测信息实时融合、编码转发,通过CPLD电路集成设计,满足了飞行载体航迹、弹丸飞行轨迹的测试任务。经过机载、炮射环境试验考核,取得了较好的应用效果。

Design of GPS telemetry coding circuit

To satisfy the demand of fusion, coding and telemetry transferring of the GPS positioning information and the other physical measured parameters in the ballistic trajectory testing and the flight-course testing of the developing extended range trajectile, rocket and robot bomb which are developed by GPS/TM technology, a new method of design of airborne GPS telemetry coding circuit is put forward. By the means of double-CPU controlling technique, double-port buffer accessing technique, it is realized to load the reprogramming, carry out the real-time fuse of measured information and code transfer. Finally by CPLD integrated circuit design, measurement and test of course of flight carriers and flight trajectory of trajectile are finished. A satisfied test results are achieved through assessing of several tests by loading in robot bomb and projectile.
