Abstract:

Aiming at the problems that some of the current GPS(Global Positioning System)  system could not provide map support and could not give map information about the location,based on 89C51 microcontroller, a GPS hand-holding system is designed and implemented by using GE(Google Earth).The system employs SR-87 module manufactured by Taiwan Progin corporation as its core GPS module. Through the Enhanced ShockBurstTMpatent agreement of RF chip nRF24L01, hand\|holding transmitter seamlessly and efficiently sends data to PC(Personal Computer) receiver. Making use of the GE's ability to support external devices, PC receiver imports the packaged data in line with international standard GPS protocol NMEA(National Marine Electronics Association) into GE software, so as to achieve positioning, navigation and other functions. Results show that the system can display information of latitude, longitude, altitude, time, number of satellites,and obtain map information with the GE on PC side. This system is valued to field sports, expedition, the environmental sciences and other fieldwork\|related activities.

Key words: google earth, global positioning system(GPS) hand-holding system, nRF24L01 chip, national marine electronics association (NMEA) protocol
