Altitude too high.

Posted by Colin Girvan on October 4, 2017 at 9:02am

We had an issue yesterday that I'm hoping someone will be able to help me with.

When trying to start a mission by activating Auto Mode we kept getting an "Altitude too high" error. It doesn't say what altitude it's referring to and everything we tried didn't help.

About 2 months ago we had the same issue after switching to 2.11, drove home switched back to 2.10 and the next day it was OK. We've been flying 2.10 up till about a week ago when I decided to try 2.11 again.

This time we had no problems and had several good flights (at a different location). Yesterday at the original site we had the same error.

I could switch back to 2.10 again but feel this is not really a good solution.

Anyone have any ideas?

Thanks.

Colin

    Yes, have sense. Thank you.

    OK - thank you.

    I would suggest that you make people aware of this as it is a simple fix, but there can be an issue with the DJI Go App.  For example, I don't often use the DJI Go App because I rely on the UgCS App.  The first time I try to login to DJI Go to change the setting I could not, because I don't have internet in western Uganda; DJI Go requires an internet connection the first time you login (it is likely the DJI Go App had updated and this meant I needed to re-login).  
    Perhaps you could make a note in the DJI users manual?

    Hi Mark,

    I'm very sorry, but if our tech support engineer doesn't know solution based on information provided it has to ask additional information.

    Flight limits are stored in autopilot, not in DJI GO. So if you never changed maximum range and altitude they were set to factory default values.

    I ran into this problem while on a job on Africa a month ago.  It was a very stressful situation as I was responsible for the high cost of mobilization for the team from the USA, Europe as well a a team of local scientists in attendance. 

     As stated above, the DJI Go App seems to be the issue.  I read this thread while I was panicing on the job.  I was very confused because I was not running the DJI Go App - I was running the UgCS App on and Android device, with a laptop for UgCS client!  Anyway today I did some testing and it seems the DJI Go app sets the max altitude, and this limit remains even when the DJI Go App is not running, or even not installed on the Android device.   UgGS really need to step up their game and make DJI users aware of this issue.  After I returned home I contacted UgCS and received the following reply (Note: I am a customer not a beta tester):

    Dear Mark,

    Thank you for reaching out to us.

    I think that we need more details about this situation.

    Can you send us:

    1. Logs from Android device:
    Device storage > Android > data > com.ugcs.android.vsm.dji > files > log_cat

    2. Logs from laptop:

    Windows
    C:\Users\USER_NAME\AppData\Local\UGCS\logs.
    where USER_NAME - the user you are logged into Windows

    Mac OS X
    /Users/User Name/Library/Logs

    Linux
    /var/opt/ugcs

    3. The mission. Use ‘Menu – Export mission’.

    4. Telemetry from the flight: Menu - Telemetry player - Export telemetry.

    All the above information is mandatory in this case.

    I will wait for new details.

    No, UgCS doesn't override max altitude/radius settings in DJI GO.

    Parameters in vehicle profile and mission used to check route only.

  • Colin Girvan October 10, 2017 at 1:34pm

    OK thanks Alexey,

    I thought that since we were using UgCS, that it's altitude values overrode the DJI Go settings.

  • Alexey Dobrovolskiy October 10, 2017 at 10:59am

    Hi Colin,
    most likely you exceeding limit set in DJI GO/DJI GO4 app. Please check limit here.
    Here can be confusing situation. Suppose you have 50m limit set in DJI GO app. And all waypoints in the route will have 45m AGL for example. But if your flight area are isn't flat some waypoints can have altitude above take-off point bigger then 50m - in such case you will get error message "Altitude is too hight".

    Thanks Anna, I seem to have 2 threads going, I originally started this thread with this problem then found another thread that was related so commented there as well. I'll try and keep to this one.

    As far as the altitude settings go, in the vehicle profile we have 'Max AMSL' set to 3000m (actual elevation 1076m), 'Max AGL' set to 600m (we never got above 50m) and in the mission parameters we have "Max altitude above gnd' set to 600m. We are flying a Matrice 600 so the Inspire restriction shouldn't apply.

    We had a waypoint next to the homepoint set at 50m then the area survey set at 200m. We normally take off manually after uploading the mission on the ground then at 30m or so we activate the mission. This usually works OK but not in this case.

    Dear Colin,


    Let me start with apologies for not answering sooner.


    Nonetheless the drone and settings in software may have several limits of AGL.


    Let’s take a look together to them:


    The first limit is in the Properties of the route in UgCS. 


    The second limit is in Profile of the drone in UgCS. 


    The first and the second limits you may change in UgCS as you like.


    But there is the third limit that exists in DJI Inspire1 Pro drone and it cannot be changed. Unfortunately you may fly not more than 500 m from Take-off AGL during one flight (from Take-off to Landing points).


    Best regards,
    Anna Moshkova
