摘要
提出一种基于EM411 GPS接收模块和PIC18F2520单片机的手持式GPS接收机设计方案。该方案具有电路简单、成本低、灵敏度高等优点,并可将接收的数据以FAT文件格式保存到SD卡中,通过SD卡将GPS数据导入电子地图,便于野外作业和户外运动使用。
A GPS receiver design proposal is presented in this paper which is based on EM411 GPS module and PIC18F2520 microeontroller. The design features simple hardware circuit, low cost, high sensitivity. The GPS receiver stores the receiving data in SD card in FAT file format and transmit GPS data to e-map through SD card.The design will bring great convenience for out of field and outdoor work.
