In the “setup” panel you can see “Hot Start” “Warm Start” “Cold Start”,
which allow you to re-acquisition the Ephemeris and Almanac. Basically,
the satellites are always moving in the sky, if Ephemeris and Almanac
data in the GPS Logger can’t meet real satellites status or if the GPS
Logger has been powered off for over 0.5 hours but you are no longer in
the previous position, then it will take more time for the GPS Logger to
obtain a GPS position fix. We suggest that you click “Cold Start” or “Warm
start” to re-acquisition.
