Abstract—Position data acquisition system is described in this paper. The system is based on Magellan Sport Trak GPS, PIC 16F628A microcontroller and personal computer (PC). Position data (latitude and longitude) is extracted from the RMC sentence of the NMEA protocol of the GPS receiver. The extracted data is displayed on personal computer using HyperTerminal communication. The real time received characters can be saved in computer using capture text command in HyperTerminal and retrieved later.

Index Terms—data acquisition system; HyperTerminal; NMEA protocol; GPS; latitude; longitude.
