3. In the “status 、 、 ” 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.
Or you can remove the battery for 120 seconds and reinsert it; this
operation is the same as “Cold Start”.
