摘　　要：利用单片机和OEM板二次设计了一种成本低又能满足性能使用要求的经济型GPS接收机。系统硬件是以Intel8051单片机为核心,采用Jupiter-TMGPS接收板二次开发、键盘、液晶显示器、RS-232电缆及其它外围器件开发设计的;应用汇编语言实现了GPS信号的提取、显示及基本的键盘控制操作等。经实验证明:该接收机单点无差分定位精度低,但比一般的手持机精度要高,需要进一步研究如何提高精度。Based on the single-computer and OEM board, an economic GPS receiver, with low cost, is designed to meet the performance requirements. The heart of this ：system＇s hardware is lntel 8051 single-computer; the system is developed by using the Jupiter-TM GPS receiving board; the hardware system also contains keyboard, LCD, RS-232 cable, and the other outer devices. The system＇s software uses the assemble language to realize picking up and displaying GPS signal, and the basic control and operation on keyboard. By the experiment, the single point and non-difference location precision of this receiver is low, but higher than the common hand receiver, so this receiver needs further research to improve the precision.
