摘要
利用GPS(全球卫星定位系统)和BDS(北斗卫星导航系统)联合定位技术,设计了一款针对移动目标的高精度定位与跟踪系统。系统主要包括移动目标通信终端、GSM网络、GIS电子地图等。其中,核心部分——移动目标通信终端硬件由ATGM331C单元、TC35I单元和STC12C5A60S2微处理器单元等构成;其软件设计主要包括:微处理器初始化、GPS/BDS解码、短信命令解码和AT命令控制等。实践测试结果表明:该系统运行稳定,且移动目标通信终端具有定位精度高、体积小、功耗低、操作简单方便等特点,应用前景广阔。
By using the combined positioning technology of global positioning system（GPS）and Bei Dou navigation satellite system（BDS）,a high accuracy positioning and tracking system for moving targets was designed. The system consists of communication terminal of moving target,GSM network and electronic map of GIS mainly. As the key part of the whole system,the hardware of the moving target communication terminal is composed of ATGM331 C module,TC35 I module and STC12C5A60S2 microprocessor. The software design includes microprocessor initialization,decoding of GPS/BDS navigation information,decoding of short message service commands and the AT command control mainly. The practical testing results indicate that the system can work steadily,and the moving target communication terminal has the characteristics of high accuracy positioning,small size,low power consumption and convenient operation. The system has a broad application prospect.
