Message
GGA
Description
Global positioning system fix data
Firmware
Supported on:
•
u-blox 9 with protocol version 27
Type
Output Message
Comment
The output of this message is dependent on the currently selected datum (default:
WGS84). The NMEA specification indicates that the GGA message is GPS specific.
However, when the receiver is configured for multi-GNSS, the GGA message
contents will be generated from the multi-GNSS solution. For multi-GNSS use, it is
recommended that the
NMEA-GNS
message is used instead.
Time and position, together with GPS fixing related data (number of satellites in use, and
the resulting HDOP, age of differential data if in use, etc.).
