    As can be seen from the video, there is a sudden satellite glitch as soon as the drone comes down. Zero satellite and need compass calibration. The error goes away after compass calibration. However after I put in a new battery the problem happens again. Compass calibration does not help. I switch off the uav, wifi extender, transmitter and kill the app. Still no good then after 3-5 trial eventually it sorted it self out.

    dji firmware 3.06 (last software update done in middle of January 2015)
    fpv booster app (latest version)

    I tried switching to DJI Vision app but it does not make any difference.

    I just noticed that the flight time on the screen got reset when it fly back. I flew a 10mins journey and it is only showing 1.4mins. The onboard video recording was cut about 1.5 before it landed.

    It appears that your trying fly a concrete seawall which more then likely contains rebar causing compass and satellite problems. Suggestion find a better locations to fly from then that concrete walkway.

    I was worried something was loose inside. That makes sense. Now I won't have to worry about losing GPS during flight.

    Thanks for help.

    If the same thing happens at a different location and you're not on concrete w/rebar then I would open the shell and check the GPS connection to the main board.
