    IMU Calibration while Sailing

    Update: successfully hand launched one of the drones off the stern of a monohull yesterday 3 times and retrieved, just motoring slowly for practice. Did get the compass calibration warning but was able to move to a slightly different position on the boat, further aft. When we sped up to...

    IMU Calibration while Sailing

    So, I was on a Leopard 50 catamaran, attempting to launch from the foredeck, because the aft deck is covered by a roof and there is the dingy back there. Could have tried to launch from on top of the roof but then there is the main, boom, mainsheets and additional movement from being higher up...

    Oh - I missed the upload part, thanks for doing that. @Meta4 - what does your analysis of the data suggest?

    IMU Calibration while Sailing

    I just flew both drones, no IMU calibration warning, so confirming that warning is not a drone issue. However, each drone gave me the compass calibration error and neither would let me start the blades or activate the auto take off feature, without calibrating. So how to ignore the compass...

    Here are links to the 2 flight records from the failed attempts on the boat, from May, are they supposed to so unreadable?

    IMU Calibration while Sailing

    Wow - thanks for all this advice! Yes, I've learned the hard way about the RTH function but had not thought to keep updating it while in flight. I've changed the function to hover instead of land, when returning to home, but will start updating the home point more regularly. I've never really...

    I have not, as a boat is always moving around a little, but will try with greatly reduced speed.

    IMU Calibration while Sailing

    I was standing astern of the drone when trying to launch from deck and it bit my leg and it did try to fly aft when launching by hand, so your idea of geographical hover is probably a good thing to test out. Even though when I launch from either point I was launching manually, rather than using...

    IMU Calibration while Sailing

    The boat was probably sailing at 6kts at most, so no more than 7mph. And likely less - I'm not likely to fly in high wind or rough seas. What happened was that I turned the drone on, calibrated the compass, set it down on deck again, and then got the IMU calibration error. I tried starting the...

    IMU Calibration while Sailing

    @Andy9: Thanks for the reply. Unfortunately when I turn the drone on, when sailing, I get the IMU calibration error and when trying to fly with that error active, the drone is not able to be controlled.

    IMU Calibration while Sailing

    Hi there: In March the non-profit I work for purchased 2 DJI Phantom 4 Pro+ Version 2.0 Quadcopters. We wanted to use them while sailing across the Atlantic Ocean. Got them set up and tested on land, good to go. Once on the boat (and they had been stored in cases upright) got the IMU...
