    I'm not sure but I suspect something has changed in Dji GO4 as far as precision landing.
    I have three locations I use all the time and all my aircraft have been able to land pretty much with 2 feet easily. Many time dead on where it took off from.
    Lately however it seems none of my birds can hit the broad side of a barn landing. I have to be uber vigilant in 2 locations because of trees nearby. Seems like every time lately it's come down over 20 feet from where it took off. Got plenty of satellites, nice landing pad for a visual target, bright sunshiny day. What the heck? I for sure have become cautious using RTH with precision takeoff as I can't trust it anymore.
    Anyone else seen this? Phantom 4 Pro, Mavic and Spark - they all have this issue.

    Have you been mixing the firmwares up or modding it in anyway, i know on the Mavic that if you drop to a lower firmware and then use a mixed one to upgrade it throws the precision landing out

    Are you sure you are using the precision landing feature?
    Unless you specifically enable the precision landing feature and let the Phantom photograph the launch point, you will only be getting the landing point accuracy that consumer GPS allows.
    That's variable and is usually within 10 feet but can sometimes be more.
    As the precision landing feature uses optical technology to recognise the launch point, it may have trouble with featureless locations like grassy areas.
    It needs a recognisable pattern or texture as well as sufficient lighting to work properly.

    The Precision landing feature may also be disabled following a firmware update and need to be enabled again.

    Absolutely - lil checkbox every time. Wait until it climbs and gets the picture - then take off.
    As I said I take off from these locations a lot - not an unknown quantity and I also use a landing pad for the visual differentiation.

    No. All firmwares up to date and Dji GO4 is up to date on both iPhone and iPad Mini 4
    Also - no warnings, ni IMU, no compass warnings - heck I even checked the Kp Index...
