MediaTek MT3329 GPS. The GPS transmits incoming NMEA (National Marine Electronics Association)
sentences at 10Hz to the Arduino Mega. The NMEA
sentences are stored as a text file on a microSD

NMEA sentences are specified electronically transmitted strings of data, containing global positioning information. For Protei_006, the useful information might include latitude, longitude, course, bearing, speed, time, date, satellite ID’s, checksum, and altitude.
