Time Synchronization with an External GPS/INS System The sensors can synchronize their data with precision, GPS-supplied time pulses. Synchronizing to the GPS pulse-per-second (PPS) signal provides users the ability to compute the exact firing time of each data point. To utilize these features the user must configure their GPS/INS device to issue a once-per-second synchronization pulse in conjunction with a once-per-second NMEA $GPRMC sentence.
