Started by Mike Sousa. Last reply by Janis Jonins yesterday. 1 Reply

HiSometimes (many times?) when executing a route the connection between the Android device with UgCS for DJI and the laptop running the UgCS Ground Station software disconnect, and they may only be a few feet from each other. Has others experienced issues with comms having connection problems? I'm using a Samsung Galaxy Note 8 and a DJI Mavic 2 Zoom.Thanks...Continue

UgCS for DJI setup

Started by Mike Sousa. Last reply by Mike Sousa yesterday. 3 Replies

HiI've been able to get a number of routes to execute but still have some questions about some of UgCS for DJi's functionality:Can I get the video recording to start at a specific waypoint? I usually start it with the 'Set Camera Mode' section of the Mission Editor before uploading.Can I have the video recording stored on the Android device? Right now it is stored on an SD card inserted into the Mavic 2 Zoom.I've looked through the UgCS for DJI manual. Is there a video of how to use the app?…Continue

Capture and save manual flight path/mission for later use

Started by Mike Sousa. Last reply by Janis Jonins Mar 15. 8 Replies

HiI'm thinking that Joystick more or Manual Mode would be the way to do this. I'd like to fly the quad, have the flight path captured and saved so that it can be reloaded and used again automatically. Are there tutorials or more directions available for using the Joystick or Manual modes? If those aren't the ways to do this, would UgCS be capable using other its facilities?Thanks...Continue

UgCS Mapper and Windows 7

Started by Mike Sousa. Last reply by Janis Jonins Mar 15. 1 Reply

I have a Windows 7 laptop with UgCS Mapper installed. When I try to run Mapper, it looks like a Box (Dos or javaw box?) come up and goes away very quickly or I would include what's in it here. Also, in Task Manager, while watching the 'Processes view, a javaw process does try to start but then goes quickly away when trying to start UgCS Mapper. Is Mapper usable at the moment? If so, does it work with Windows 7? If both questions are affirmative, does it work with output from a Facade…Continue

HiIs it possible to sync the clocks between the drone (in my case, a Mavic 2 Zoom or a Matrice 210 RTK) and the PC with UgCS running? This way I wouldn't need to account for an offset when geotagging an image collection.ThanksContinue

I’m getting errors like area too large. Is there a limit to how many images you should process
Comment by Ricardo Procopio Nieto on August 14, 2018 at 4:07pm


I am trying to read telemetry with version 2.13. But in the latitude and longitude these erroneous values ​​appear:

{"id": "TT_LATITUDE", "value": 0.33958137}, {"id": "TT_LONGITUDE", "value": - 1.7310266}

You have to do some calculation to obtain to get the positions like this: "19.456566, -99.180498.61.17" WGS-84.

Thanks in advance

Hi guys:

I'm new to UgCS and drones. I've been testing version 2.12 with Phantom 4 DJI with the Java SDK from here:

Following the examples, I have managed to read telemetry, send commands and upload routes, but I have two limitations:

1.- When the telemetry is connected with version 3.0, it does not work correctly.

2.- I don't know how to manipulate camera rotation and drone movements. I tried sending the command "direct_payload_control", but it gives me the error: "command not registered".

Reading this documentation:

I understand that you have to register the command, but I still do not know how. Please someone help me.

I am working on UgCS for muti-Drone(arducopter).

I have some question now, I have tested the 2 quadcopters with ardupilot and here+ RTK GNSS, ESP-07 WIFI telemetry . but UgCS Pro version have lost the telemetry up/down links  on about 30~40 meter altitude. 

I have tested in LOS environment with TP-Link wifi router .

I want to control the drones over 150m at least.

please let me know how to solver this problem . which telemetry module I use for multi-drones.



Comment by DEEPESH PARATE on February 9, 2018 at 10:11am

I'm working on writing a parser code to convert xml exported from ugcs into a format suitable for paparazzi to use. The current flight plan xml that I have from ugcs has a completely different format from the one of paparazzi so I'm thinking of going for px4 flight plan. Can someone please tell me if it's going to be helpful or not?

Comment by Isabelle Heitz on February 2, 2018 at 11:29am

I have the same problem. How did you solve your problem ? 

Comment by belkacem guerbasse on November 20, 2017 at 8:22am
I installed the Android application I use a multirotor with a dji A3 I have a problem I have no indication of battery level
Comment by juan pablo gayoso on January 19, 2017 at 11:11am

is possible read mission file from UgCS to MissionPlanner, in both directions.

Comment by Marshall Cant on December 26, 2016 at 8:54am

I have the same problem.  My "Overshoot" field is also set to 0.

If you reduce overlap you also reduce the quality of the results.Pix 4D recommends 70% overlap (as does most other photogrammetry software).

Please explain how to correct this and have the UAV follow the outline of the area.



Comment by Alex on December 26, 2016 at 3:57am

Adam Kelly, you got to make lower Forward overlap to get not so big overshoots.
