摘要
主要描述了基于北斗2代卫星的定位跟踪系统的实现,该系统由北斗卫星系统、CDMA通信网络、信标终端、服务器和监控中心组成。信标终端启动时间小于45 s,语音拾取范围2~3 m,定位精度小于10 m。具有精度更好、通信速度更快、安全性更高的特点,并具备CDMA信号丢失下的信息自动存储、信号恢复后的信息补传功能,能够完整地还原目标的整个运动轨迹。
The realization of a positioning and tracking system based on BD2 satellite is described in this paper. The system is consisted by BD satellite system, CDMA communication network, beacon terminals, server and monitoring centre. Beacon start time less than 45 seconds, monitoring scope 2~3 meters, positioning accuracy is less than 10 meters, performer better in accuracy, communication speed and security level, meanwhile this system have the function of automatic data storing in the situation of dropping CDMA signal and data resending after that, which makes the recurrences of whole target movement track possible.
