Matching Elevation Sources

Started by Luke. Last reply by Alexei Yankelevich yesterday. 1 Reply

Hey all, when I upload my DSM (or DTM) that I made with Pix4d it is set approximately 52 meters below the SRTM elevation source (it looks like a big bowl in the ground). I am trying to match the sources so I can plan missions that could extend from my DSM area into the SRTM area.  I have tried changing settings in Pix4d such as the Geoid Height above WGS 84 (+52m) I have also tried other vertical coordinate systems. Every time I try and upload the DSM made with other settings besides the…Continue

We're having a few ongoing issues with UgCS were looking for help with.1. UgCS for DJI App Crashing. It seems like the app crashes quite alot.

UgCS Unable to Upload Routes - Command is Timing out and not uploading the route. Seems as per the troubleshooting note in the manual below.From the manual troubleshooting…Continue

Feature request. Flight timer, Reverse waypoints, Load KML without internet, Turn off KML on map

UGCS is Excellent. But we need more and more ))) For two weeks I performed 10 to 15 flights a day in field. So I have some Feature request list:1. Flight timer - on mobile and PC to show how long my quadrocopter is in air. So it got to start count after Takeoff procedure.2. Reverse waypoints - I wan't to change order of waypoints in Photogrammetry tool to start from farest point and land near Takeoff point. So the last waypoint will be maximal near me and when quad have few % of battery it will…Continue

Plan mission including Digital Surface Model as 3D object

How could I include a Digital Surface Model (DSM) (with native Geotiff format) as a 3D Object to avoid hitting objects when creating missions at low AGL?Continue

Photogrametry Missing Pictures UGCS

Started by Steve Cudmore. Last reply by Alexey Dobrovolskiy Jul 29. 5 Replies

We're having issues with our photogrametry flight routes missing taking some pictures.We thought flying at 3m/s horizontally may have been a culprit but even with a wait set at 1 second before snapping a picture at each waypoint - the odd time the camera doesn't trigger. We've tried flying at 1m/s speeds and still have this issue of missing pictures. We experienced this all morning today through a total of 8 photogrametry flights. One example of this from a route: We expected 75 pictures and…Continue

UGCS Battery % showing 0% but Voltage Normal A3

Started by Steve Cudmore. Last reply by Steve Cudmore Jul 27. 5 Replies

Has anyone had this problem with the battery percentage showing 0% with an acceptable voltage? This is on a custom airframe with an A3 Pro controller & LB2. Has this display in both the desktop and mobile version. The DJI Go app doesn't show anything wrong but only shows a voltage not percentage. Pack indicates ~65% with a battery checker. Drone was erratic last time we tried a test flight and wondering if this could be the issue. The voltage shows fine but not the %.Thanks in advance,SteveContinue

Linear survey (corridor) with large areas

Started by lanzo Jul 13. 0 Replies

I am planning to do a big survey >200Km of a road.In Mission Planner I can plan a mission using the Corridor option, but the road changes width in some areas, so I have around 500 meters of width in the most of the survey and some points where I need to map up to 1000 meters os width, Corridor has only the option to choose a fixed width.I wonder if ugcs can plan this kind of mission automatically creating the needed strips only in that areas.Thank youp.s.I have another big problem with MP…Continue

Terrain Following to/from Waypoints after/before Photogrammetry Segment Waypoints

Started by Justin. Last reply by GocGoc Jun 21. 3 Replies

Has anyone ever noticed that in pre-2.13 versions of UGCS when going from a beginning waypoint (single waypoint segment) to the first photogrammetry waypoint that the line connecting the two waypoints would follow the terrain if AGL tolerance was set in the photogrammetry segment's parameters? The same was true after going from the last waypoint in a photogrammetry segment to an ending waypoint (single waypoint segment) near the home location. It seems in 2.13.537 that this no longer occurs for…Continue

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?

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

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.

Comment by Adam Kelly on December 26, 2016 at 2:51am

Hi - I'm new to ugcs. I'm planning a mission and I keep getting big overshoots using the photogrammetry tool. I've attached a screen shot. Anyone know why this is happening? I have tried changing pretty much all the variables one at a time, nothing changes these overshoots. It suck up a lot of flight time to travel this extra distance.
