    i think he'd also like to know what would happen rather than just a "nope". same goes for me,would it hover,would it land,would it fly away,should i say goodbye to my chick??

    GPS is essential for the Phantom to be able to RTH.
    But losing GPS isn't something that should happen unless you fly in a deep canyon, under forest canopy etc to lose your view of the sky.

    So is there a way to counter this like any tips you could give to make this less probable also if it reasablished gps would it then return to home.

    if the signal is lost and gps comes back pretty sure it will come home is really rare to lose gps signal more likely to lose video feed and signal lost before that would ever happen

    By default, your Phantom will auto land at its current location 10 seconds after the signal has been lost when GPS is not available. You can choose an alternate behavior in the following section of DJI GO:

    If you set it to "Hover", that might give you enough time to reestablish the connection before it lands. If you're not able to reestablish the connection, your Phantom will auto land at its current location when it reaches the critically low battery level.

    Ok thanks I asked the question because I took the phantom for a flight yesterday over my neighbourhood when I took of I had 8 satellites then halfway though flight I had a gps loss flash up on app and the return to home option disappeared for a second the quad was quite high up and thought it might fook off over the horizon

    Would this happen because of rc signal loss meaning the quad probably still had gps

    Your Phantom has its own GPS receiver on board. That's where its GPS data comes from. If the on-board GPS receiver cannot connect to enough satellites, your Phantom will not know how to make it back to the home point.

    Yea I know that, I was unsure what it would do if it did lose gps and controller connection and also if the dji app said no gps when i was flying because it wasn't receiving the information from drone or the drone had lost its gps connection to satellites the drone did hold position when hovering so im assuming its the connection between controller and drone but it got me thinking.

    It will do whatever is selected in my screenshot above. When any type of RTH is initiated, your Phantom will always auto land at its current location if it does not have a GPS connection.

    Cool, so does gps lost flashing on screen of dji go app along with the icon for return to home missing mean that the information connection between drone and controller has
    been lost so the command can not be sent until wifi connection resumes.

    That's only if you lose signal from RC to the bird. Has nothing to do with the birds loss of GPS.
    Can't agree with this post.


    I think a greater thought would be how to address this issue?

    Maybe something where the birds stores in memory the input of stick commands and percentages. If God is lost for x seconds; it will attempt to reverse all of those commands and bring it as close to home as possible. We can assume that it would possibly get close to "home" without GPS. At the least; it would come across a known GPS signal spot since it did have a signal once iodine a time along the flight path.

    If your Phantom loses GPS, it does not RTH. It will only RTH when the remote controller signal is lost. And, at that point, it's RTH behavior has everything to do with GPS if you're using the default DJI GO settings.

    As your screenshot states, this setting is only when the "Remote Controller Signal Lost".

    For example, if I power off my remote controller (assuming that the Phantom has GPS lock) it will either return to home, hover, or land. This setting has no bearing on what will happen "after the signal has been lost when GPS is not available" as you stated.

    If the signal has been lost AND GPS is not available, how would it return to home?

    It won't return home. It will auto land at its current location by default.
