NMEA-GP-GLL

Description:

Standard NMEA: Geographic position latitude and longitude. Latitude and longitude of vessel position, time of position fix and status.

This message is actually NMEA-GN-GLL, as it uses information from all GNSS constellations (GN), not GPS only (GP). However, we publish it as NMEA-GP-GLL to maximize compatibility.

Configuration:

NMEA-GP-GLL_GNSS for combined (average) output from both receivers
- The time and position data is the average between GNSS1 and GNSS2.
- The positioning mode is from the “best” receiver
NMEA-GP-GLL_GNSS1 for output from GNSS 1 receiver
- This is the standard NMEA GLL for GNSS1.
NMEA-GP-GLL_GNSS2 for output from GNSS 2 receiver
- This is the standard NMEA GLL for GNSS2.
NMEA-GP-GLL_FUSION for output from Fusion
- The time and position data is from fusion
- The positioning mode is from the “best” receiver

Notes:

These messages does not contain any information that would let one tell them apart. Do not enable more than one of these in the same port.
This message is according to NMEA 0183 v4.11 (and erratas).
It uses the “GP” talker ID even though the navigation solution is multi-GNSS.
