GPS time synchronization. GPS receiver requirements. Minimum: GPS receiver that works with user chosen software; this requires some combination of GPGGA, GPRMC, GPZDA, GPGSA, and GPGSV sentences. This provides accuracy of between 1 and 2 seconds, and includes most, but not all modern GPS receivers. Better: USB GPS receiver with the NMEA 0183 ...
