摘　　要：GPS定位广泛应用在个各行各业的定位系统中,针对一款高精度的GPS接收机,进行了一种实时GPS数据记录仪的系统设计;系统设计以C8051F020为主控处理器,通过控制程序将高精度差分GPS OEM模块接收的定位数据实时存储在CF卡中,主要包括GPS数据接收机配置和CF卡存储设计;同时,系统设计了基于Windows操作系统的专用上位机软件来进行扇区的读数和数据导出,其功能包括扇区区间的选择,扇区数据的导出,磁盘格式化等;通过完整的硬件和软件设计,在可供用户二次开发的GPS OEM板上设计实现了一种高精度的可配置的实时GPS数据记录仪;设计的GPS数据记录仪具有小巧,轻便,可稳定工作于恶劣环境等特点,并且可以满足单点和差分GPS数据的记录;通过功能试验和验证,该系统工作稳定且可靠性高。GPS positioning system has been widely used in the positioning system of a wide range of industries. By means of a high-- pre- cision GPS receiver, this paper aims to design a real--time GPS data recorder. The design of this system is based on the C8051F020 processor control system and the real--time location data received from the high precision differential GPS OEM module is stored in the CF （Compact Flash） card through the control procedure. These parts mainly include the configuration of GPS data receiver and the design of CF card stor- age. At the same time, this system designs the dedicated PC software which could be used in Windows operating system for reading the sector of CF cards and export the data easily, the function in this part include the selection of sector interval, the export of sector data and disk for- matting, etc. Through the complete design of hardware and software in this system, a high--precision and configurable real--time GPS data recorder is designed based on the GPS OEM board, for the more, users could make a secondary development on this project. All in all, this GPS data recorder has characters of small size, portable and stable working in bad environments, and can satisfy different data records type such as single point and differential GPS. At the end, through functional test and verification test of this system, this equipment is stable and reliable.
