COG/SOG section
This section displays the Course Over Ground (COG) and the Speed Over
Ground (SOG). The COG and SOG are calculated together with the position
and are only shown when the position is updated.
COG is the average direction travelled in the time set by COG Smoothing
(DGNSS > Settings > General > COG Smoothing).
SOG is the average speed, calculated over the SOG Smoothing time
(DGNSS > Settings > General > SOG Smoothing).
Quality tab
The Quality tab provides more detailed information about the current
position.
• Satellites in view shows the number of satellites above the minimum
elevation mask.
• Satellites in use shows the number of satellites used for calculating
the position.
• Correction age is the age of the currently applied differential
corrections.
• Correction reference is the reference ID of the radio beacon station
in use.
