NOTE: Why perform a GPS reset?
If the previous GPS fix position was more than 500 km or 12 hours apart from
your current position and time, it will take significantly longer than the stan-
dard TTFF time to get a GPS fix. This is due to the nature of the GPS algo-
rithm and rotational velocity between the satellites and planet Earth, and
deemed normal. Perform a GPS reset in the main menu to get a faster GPS
fix.
