Hi, I've seen that anytime the number of used satellites given by SatellideUsedCount is different from the Number of Satellite which are used only analyzing data obtained by GetSatellitesData().
Why the number of used satellite is anytime different with these 2 methods?:sign0085:
I don't know, how different are they? I would expect them to be the same or maybe differ by one depending upon when the data is updated. That information is being passed to the library by the GPS unit so only it really knows why they are different. You could use my http://www.b4x.com/forum/additional-libraries/3319-gpsdrivernmea-library.html to look at the actual NMEA sentences from the GPS driver and see if that gives you some idea of what is happening.
The Number of Satellites is the number of satellite signals being received in total, whereas the SatellideUsedCount represents the satellites where the quality of data received is high enough to be used in the position calculation.
