NMEA-GN-ZDA

Standard NMEA: Time and date

NMEA-GN-ZDA_GNSS for combined (average) output from both receivers
- The time is the average between GNSS1 and GNSS2.
NMEA-GN-ZDA_GNSS1 for output from GNSS 1 receiver
- This is the standard NMEA ZDA for GNSS1.
NMEA-GN-ZDA_GNSS2 for output from GNSS 2 receiver
- This is the standard NMEA ZDA for GNSS2.
NMEA-GN-ZDA_FUSION for output from Fusion
- The time is from fusion.
NMEA-GN-ZDA_GNSS1TOS for top-of-second 1Hz strict NMEA output from GNSS 1 receiver
- Like NMEA-GN-ZDA_GNSS1, but only the top-of-second message
- Always strict NMEA (the high-precision NMEA configuration has no effect)
- The intended use is for time sync applications that use the PPS output of GNSS1
- See also NMEA-GN-RMC_GNSS1TOS and NMEA-GN-GGA_GNSS1TOS
NMEA-GP-ZDA_GNSS, NMEA-GP-ZDA_GNSS1, NMEA-GP-ZDA_GNSS2, NMEA-GP-ZDA_FUSION and NMEA-GP-ZDA_GNSS1TOS
- Legacy messages. These messages also have GN constellation but the talker ID is “GP”
