gnss

Syntax

gnss

Context

show>mda

Description

This command displays detailed GNSS information, including position and satellite information.

If a GNSS fix is acquired and then subsequently lost by the node, the last known GNSS fix data continues to be displayed in the CLI. When a GNSS fix is reacquired, the GNSS data is updated to match the new fix.

The last GNSS fix data is not preserved after a power-cycle, admin reboot, clear mda 1/1, or shutdown command is issued for GNSS.

Output

The following output is an example of GNSS information.
