摘　　要：为克服传统GPS定位系统在室内或建筑物密集区存在盲点的缺陷,更好地满足个人定位的需求,基于GPSOne技术,提出了一种便携式个人定位终端的设计与实现方案。该终端由定位单元、主控单元MCU、UIM单元、LED显示等模块组成,其中定位单元使用AnyData公司的DTGS-800 GPSOne模块,主控单元选用超低功耗的16位单片机MSP430F147,借助于AT指令与CDMA网络实现了对个人的位置监控、定位和报警等功能。测试结果表明,该终端的定位误差室外小于20 m,室内小于500 m,初始定位时间小于20 s,报警信息能在1 s内传送到CDMA网络控制中心。In order to overcome the defects that the traditional GPS positioning system exists blind spots in the areas signal shield, and to meet the needs of personal location,this paper presents a design and implementation scheme of a personal positioning system based on GPSOne technology.The terminal was composed of the main control unit （MSP430F147）, positioning unit （DTGS-800）,UIM element, LED display modules and other modules.This system is designed to realize personal position monitoring and indication with the help of the AT command and CDMA network.A portable and easy-to-use terminal unit with low power consumption was implemented.Test results show that the terminal positioning error is less than 20 m outdoor and 500 m indoor, the initial positioning time is less than 20 s,and alarm information can be transmitted to the CDMA network control center within 1s.
