NMEA-GX-GSV - Xsens Automation & Mobility

Configuration

NMEA-GX-GSV_GNSS for combined (average) output from both receivers

The list of satellites contains the union of satellites used by GNSS1 and GNSS2

NMEA-GX-GSV_GNSS1 for output from GNSS 1 receiver

This is the standard NMEA GSV for GNSS1.

NMEA-GX-GSV_GNSS2 for output from GNSS 2 receiver

This is the standard NMEA GSV for GNSS2.

NMEA-GX-GSV_FUSION for output from Fusion

The list of satellites contains the union of satellites used by GNSS1 and GNSS2

These messages do 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).
This message is output mutiple times per epoch. A set of GSV sentences is generated for each combination system (GNSS) and signal.
This message uses the per-system talker IDs and NMEA v4.11 satellite numbering.
