    iosd mini altitude way off

    When I landed today, my iosd mini altitude said 20 meters. I do not know what it started out with, but it seemed off the whole flight. I was wearing goggles so I didnt have a visual. The telemetry from my Spectrum Rx was correct, so I dont think it was barometric. All other NAZA V2 GPS functions were fine. Any ideas ?
    Thanks !

    I was just informed that an advanced IMU cal will fix this. Apologies if that was common knowledge.

    You are right, it won't fix it. Barometric (or GPS, if used) sensors will calculate altitude and are prone to some degree of error. The IMU is something else entirely, it measures accelerations and gyrations, not altitude.
