    Naza M GPS lock issues

    Hi All,

    I was wondering if anyone has had issues with GPS lock with Naza M?

    I basically put the Disco in the air and randomly the GPS acquires satellite lock (led blinks green) only to loose it 20 seconds later ..... the processes repeats randomly.

    I have read elsewhere that maybe the Lawmate Tx could be responsible for this ?

    Anyone have any ideas ?

    Thanks,
    Serge

    You can make a picture of your Disco and then we can tell you if your lawmate is too close to your GPS.

    Have you already calibrated your Naza GPS with the calibration dance?

    Thanks, I did not realise the compass calibration was required for the GPS lock .... but it seems the GPS unit functions as a whole and hence the green indicator light does not directly indicate GPS lock status but general functioning. I have now done the compass calibration and put in a test flight this evening. It worked much better :-)

    I have also move the VTx Antenna another 1.5cm (I know ... not much) from the GPS :-)

    Attached is a picture of how it looked before, I have simply moved the antenna to the other side of the arm.

    Thanks,
    Serge

    OK guys, happy to report that after several more flights the GPS is locking on target well! So that issue is now ticked off.
