Questions & Answers
Q: Does UgCS collect any personal data?
No, UgCS software does not gather any user’s information.
Q: Does UgCS refer to any external resources via the internet?
UgCS requires an internet connection only to validate the license with the UgCS license server, to download map tiles (if maps are not cached) and to download DEM from public sources:
Installation under local user account
Q: Can UgCS be used under local user account? “An error occurred during the installation process. Please contact support.” Window occurring when trying to install UgCS .
UgCS installation requires full local PC administrator permissions. If it is necessary to install UgCS for user account with local user permissions:
1) Change user permissions, grant full local administrator rights
2) Install UgCS with administrator permissions
3) Change user permissions, remove local administrator rights
Providing full permissions to the folders and running the installer as a local administrator will not work!
Route export and mission export
Q: What's the difference between route export and mission export?.
Mission export saves vehicle profile and settings, while route export only saves waypoints.
Route and mission export
Q: How do I export route and mission?.
To perform Mission export:
Navigate to Menu on upper right corner in UgCS
Select option Export mission

Maximum Flight Altitude is Limited
Q: I have purchased UgCS license but my routes are still limited to 120 m in altitude.
You can change the maximum altitude in the profile of your aircraft. Run UgCS, go to Main Menu - Profile - find your drone in the list - click ‘Edit’ and change "Max. altitude AMSL, m" or "Max. altitude AGL, m" to the desired value. Then click ‘Save’. Also, when creating the route, check that in Route Parameters “Maximum altitude above ground, m” is set to the desired value.
Maximum Fence Radius is Limited
Q: I have purchased UgCS license but cannot create routes further than 500 m from starting point
Cannot find UgCS activation code
Q: I have purchased UgCS license. How do I activate it?
Upon purchasing UgCS license from www.ugcs.com you will receive an e-mail with your activation code.

Cannot connect UgCS desktop and UgCS for DJI mobile application
Q: Cannot connect UgCS desktop and Android mobile app.
Firstly, please, make sure you are using the latest version of UgCS for DJI on your mobile device.
- create a Wi-Fi hot spot on your mobile device and connect your laptop to it directly
- disable antivirus and firewall for testing purposes
Also, in UgCS for DJI Android app settings set these options:
- Turn on ‘Enable SSDP’. Menu - Advanced - Enable SSDP check mark.
- Turn off ‘Enable UgCS direct connection’. Menu - Advanced - Enable UgCS direct connection check mark.
If after these steps the connection is still not possible, please send us the logs from your mobile device and your computer to firstname.lastname@example.org.
Logs of UgCS desktop are located:
C:\Users\ [USER NAME]\AppData\Local\UGCS\logs
Logs of UgCS for DJI (Android device)are located:
- Device storage > Android > data > com.ugcs.android.vsm.dji > files
How to change the starting point of a route?
Q: How do I resume the route from the last point after I returned the drone home for a battery change?
If there is a need to interrupt the flight for battery change or any other reason, proceeded route is being memorized. To resume the flight, choose “Upload” for the route. For partially completed route, a dialogue with four options will be displayed:
• Continue route. This option allows to continue the route exactly where it was dropped.
• Start route from the beginning. The mission will start from first waypoint.
• Start route from waypoint #. This option will send the drone to the specified route waypoint, from which it will proceed with the mission.
• Take-off to route’s first waypoint#. In case the mission area are further than 30 meters from the initial drone location, an additional waypoint is required to overcome 30-meter safety distance. This checkbox will send the drone through this first waypoint onto the mission.
UgCS detects Naza-M v2 as Wookong-M
Q: Naza-M V2 autopilot is being detected as Wookong-M
Note: Starting from UgCS 3.4 Naza-M v2 is not supported. If you require an old version, please contact UgCS support
Due to how the Naza-M V2 autopilot identifies itself, it will oftentimes be recognized in UgCS as Wookong-M. To make it correctly be recognized as Naza-M V2, do the following:
Locate the file "vsm-dji.conf", which by default it will be located:
C:\Program Files (x86)\UgCS\bin\vsm-dji.conf
- Make sure that UgCS application is not running.
- Open the file in a text editor software.
- Find the following lines:
- Name: vehicle.dji.report_naza_as_wookong
- Passible values: yes, no
- Default: yes
vehicle.dji.report_naza_as_wookong = yes
- Change the value of the last line from “yes” to “no”
vehicle.dji.report_naza_as_wookong = no
Stop & Turn not working correctly
Q: I’m using the Stop & Turn turn type but when the drone gets to point A, it stops, and then it starts to fly while turning at the same time to point B. It does not stop and turn.
This is a particular problem related to DJI autopilots. It is caused by a POI (Point of Interest) action. By default circle mission segments have this action. So to solve this problem you might need to use the circle segment (or POI action) in a separate route from the rest for Stop & Turn to work properly.
How to unlock No-Fly Zones for DJI drones
Q: How to unlock No-Fly Zones (NFZ) for DJI drones?
To plan and fly missions in restricted areas the NFZ has to be unlocked in two levels:
UgCS has in-built No-Fly Zones. NFZ have to be disabled in UgCS. It is possible to do so in Pro and Enterprise versions.
DJI autopilots have their own in-built No-Fly Zones. To fly in these zones you will need to remove DJI’s Geospatial Environment Online (GEO) restrictions for your drone. More detailed information on how to do that is available here
Photogrammetry tool for orthophoto maps
Q: How to use the Photogrammetry tool to create orthophoto maps?
Photogrammetry tool vs. Area Scan
Q: Can you allow AGL altitude to be the main parameter instead of Ground Resolution in the Photogrammetry tool?
It’s not always necessary to use always Photogrammetry tool. We have the Area Scan tool exactly for this purpose. In Area Scan tool you are able to plan your flight using either AMSL or AGL altitude.
Overlap in Area Scan
Q: Is there a forward overlap option available in the Area Scan tool?
For this purpose, please use the Photogrammetry tool. Then you will be able to easily adjust forward and side overlaps.
Q: Mostly orthophotos are created with at least 80% side and 80% front overlap - how this can be changed?
Choose the Photogrammetry tool. In windows for Forward overlap and Side overlap insert your required parameters in %
Undo action in UgCS
Q: Is there an Undo action in UgCS?
Not in current version. We are evaluating to add this feature to future roadmap.
How to import DEM (Digital Elevation Models) in UgCS?
Q: How to import DEM (Digital Elevation Models) in UgCS?
The process of DEM import into UgCS in details is described in "How to" section >>>
Message "There are too many active elevation sources....
Q: What does this message "There are too many active elevation sources...." mean?
The message "There are too many active elevation sources...." is not an error, it is warning message. Elevation data may contain 3-4 layers. That is why when you are importing your elevation data a new layer will be created.
To get rid of this message please deactivate one of the current elevation sources.
2000m restriction warning message
Q: I can not upload a route because the distance of the first and last waypoint is more than 2000m. How can overecome this problem?
DJI restriction is 2000m between two adjacent waypoints, first and last waypoints are considered as adjacent too for some DJI drones. For Mavic series, the first and last point may be further than 2 kilometers.
If it is necessary to finish the mission within more than 2000m from takeoff position, you have to create route till your desired location, then add additional waypoints back to takeoff location, so the last waypoint is closer than 2000m. At the real landing location you can add wait action, so drone stays in the air. When drone has reached the location, overtake control and land the drone manualy.
Can I import DXF, KMZ or KML as a route into UgCS?
Q: Is there an option to import a boundary or a polygon into UgCS as a route from CAD (dxf) or a polygon from Google Earth (kmz)?
UgCS does not support import routes from CAD (DXF) or a polygon in KMZ, but it does support route import from KML. Detailed import process is described in "How to import KML from Google Earth into UgCS as a route" instruction (PDF)>>>
Q: Is there a tool in UgCS that shows all areas that you have downloaded as an offline map, similar to custom elevation data?
There is no exact indicator showing where the maps have been pre-cached and where they have not - when switching to offline places with un-cached maps will be blank. For offline work, it is recommended to use your own geotiff or pre-cached map data. Detailed information on how to set maximum cache size is described in the UgCS desktop user manual section 'Custom maps' and 'Offline maps'
There is also an option to use your own map server from which UgCS takes map tiles.
Q: Can I fly offline?
There are several preparation steps to fly in offline mode.
- Download maps in UgCS desktop for offline use, instructions available on our Wiki page
- For connection between Android device and UgCS desktop you can use dedicated WiFi router that does not require internet connection to create WiFi network. Any mobile hotspot device should work, also indoor router would be fine, if you manage power resource for it.
- As Android device will not have internet connection too, to have maps visible on Android device, you can select map provider Geoserver in UgCS for DJI setttings, Map provider, choose Geoserver map.
- For repeated routes, when you are absolutely sure about routes you have to flight, know exact takeoff location, you can use only Android device without UgCS desktop connected. Here are the instructions on how to fly without Ugcs Desktop.
Q: I'm behind network firewall, how can I start UgCS?
Pass the below info to network administrators
|https://nominatim.openstreetmap.org/search||443||HTTPS, TCP/IP, SSL|
|https://activation.ugcs.com||443||HTTPS, TCP/IP, SSL|
Changing flight direction
Q: Can the direction of the flight be changed within a route?
After creating the route, you can click on ‘Route parameters’ and click on ‘Invert segments order’. This will reverse the order of all mission segments making the first waypoint the last and vice versa.
Determination of AMSL flight height
Q: How does drone determine its current AMSL height?
AMSL is determined according to the terrain data at the current location in combination with data given by the drone’s barometer or GPS unit (depending on the type of drone and configuration). There may be some inconsistencies where the terrain height changes very quickly. Use the Take-off point altitude function in UgCS to set the Take-off height correctly.
Information on how to set height can be found in the UgCS desktop User Manual in section 'Take-off point altitude'
Pausing the flight
Q: Is there a way to pause in flight if another aircraft enters my airspace?
Yes, you can do either of the following actions:
- Press “Hold” button in UgCS to pause the flight and make the drone hold it’s current position
- Press Return Home to make the drone return to the home location
- Press Land to make the drone land at its current position
- Switch the drone into manual mode and steer it away from danger using the RC

Q: The profile of my camera does not exist in UgCS. How can I add it?
You can create a profile of any custom camera that you have and its capabilities will be taken into account when planning routes in UgCS. More details can be found in our user manual section Payloads.
Triggering two cameras
Q: Can two cameras be triggered in one flight? For example one - visible light camera and the other - IR?
It is possible to add two camera profiles to one drone in UgCS, but cannot trigger them simultaneously. Therefore a hardware setup is needed that can trigger both cameras simultaneously with a single PWM signal.
Taking photos more than once per 3 seconds
Q: Can any drone camera take more than one photo during a 3 second period?
After a photo is taken, the camera records the image on the memory card and during this process, the camera cannot take any pictures. Two or more seconds are needed for example for a Zenmuse-X5S camera in interval mode between photos.
For example, to take max high-quality resolution photo the trigger time should be:
- for JPEG 2 and more seconds,
- for RAW 3 and more seconds.
Please refer to technical parameters of your camera for the minimum supported trigger interval.
Import a building model
Q: How do you import a building model in UgCS?
To display 3D buildings on the map of UgCS and to take them into consideration when calculating a route, import 3D models of buildings.
To import 3D building models, click the Map options (globe icon at the top right-hand corner of the screen), click the Map layers button, select 3D objects tab.
Add a unique name and upload 3D model via “upload” button. Browse for the uploaded models in KMZ format.
It is possible to change the models from enabled to disabled source list. «Focus» button will displays the region of the map of the imported object.
