Abstract: This paper introduced the designing and developing of a locating and communicating terminal. Firstly introduced the hardware system development, which based on the ST20-GP7 and STB5610 chip-set, then introduced the development of the software system that based on ST’s Real. Time kernel STLite/OS20 and the GPS soft library, finally, introduced the GPS’s datapacket format of NMEA-0183 and the usage AT command of GSM SMS. The authors supplied a valuable reference and example for GPS locating application.
