摘要
随着GPS技术的广泛应用,其终端设备的功能越来越多,硬件成本越来越高,减缓了GPS设备的民用普及步伐。本文提出一种以ATmega16单片机为核心的利用Motorola M12模块进行地理定位的低成本经纬度数据接收系统,介绍了ATmega16和M12模块的软硬件接口以及利用M12模块采集定位数据的方法。经测试,系统的单机静态定位精度≤7.81 m,符合民用要求。
With the far-flung application of GPS technology, GPS terminals become more multifunctional and demand more hardware cost, which is slowing the speed of its popularization. A GPS longitude and latitude data receiving system based on ATmega16 and GPS module M12 is introduced in this paper. The hardware and software interfaces between ATmega16 and M12, as well as the applied method for M12 to collect GPS data, are presented in this paper. According to the testing data, the single-machine static positioning precision is no more than 7. 81m, which would meet the target of civil application.
