    Hi Erel,

    I already see sometimes wrong values given by your GPS-Addon.

    For example: normally I get the number of received satellites through:

    gpssat.Text = gps.NumberOfSatellites

    Sometimes I get values which are still wrong (numbers > 100 etc.)
    Also on other values like Altitude, position (long, lat).

    This problem occurs around on 1% of the runtime.
    I'm not pretty sure if its a problem of my gps-unit within my mobile or maybe a short bug.

    Are there any way to assist finding the problem?

    Most values are directly parsed from the GPS NMEA strings.
    You could compare these strings to the values you get.
    Just log Serial.InputString before passing it to the GPS object.
