The Ultimate Guide to the LTN-92 Manual: Navigation, Operation, and Troubleshooting

Solution from the manual:

The manual specifies that the LTN-92 only accepts NMEA GGA and RMC sentences at exactly 1 Hz, with a specific talker ID of “GP”. It also requires the GPS to output a 1PPS (pulse per second) signal on a dedicated pin. Standard GPS receivers often output 5 Hz or 10 Hz, which the LTN-92 interprets as noise. ltn-92 manual
