UgCS DAT files

Started by Colin Girvan. Last reply by Alexey Dobrovolskiy yesterday. 5 Replies

Hi, I just discovered the mission DAT files on my android tablet running UgCS for DJI.These seem to be different to the DJI DAT files stored on the drone itself. I tried uploading them to CsvView to convert to a CSV file but it wouldn't read it. Is there a reader or viewer for these files?The reason I'm trying to access these files is I'm trying to come up with a process to geotag Tiff files. Is there a possibility tiffs will be added to UgCSs geotagging tool? That would be great and the best…Continue

UgCS direct connection

Started by Colin Girvan. Last reply by Colin Girvan yesterday. 2 Replies

In the past we have had issues with the UgCS for DJI not connecting to the laptop.From reading some of these discussions we are not alone.Is there any thought of connecting the PC running UgCS directly with the transmitter via USB? You would be tethered to the laptop (15 foot cable) but I feel this could be a more reliable option.Thanks.ColinContinue

UgCS client connect to multiple drone, data mismatch

Started by Priya Sharmila. Last reply by Alexey Dobrovolskiy yesterday. 4 Replies

I was working with UgCS for single pixhawk. It was working fine and then I tried to use UgCS .Net SDK to receive the telemetry data and succeeded.Later I wanted to go for multiple pixhawk. At first, I connected my pixhawk and my laptop with the 433Mhz radio. Now, I tried to connect with multiple pixhawk with single radio connected to my laptop.I could see the new pixhawk turned ON and not the old one. But the telemetry data I receive belongs to the first pixhawk. This happens in UgCS client…Continue

Do route Lat/Longs get converted when adding via SDK?

Started by Stevod. Last reply by Stevod on Tuesday. 2 Replies

I am creating a new route programmatically, and I am successful in adding that to the server. However, when I open the mission in the UGCS client, they seem to have transformed into other values, and can't find the elevation. Is there a transformation when the lat/long is sent to server?I'm using EPSG 4326 for my coords.First attached screen grab shows the cords in VS, and the second is the transformed values.StevodContinue

UgCS Mapper

Is there any documentation or tutorials on UgCS Mapper? I DL'd UgCS Mapper and tried it on a few different data sets which matched closely to Agisoft's camera alignments. I just didn't really see much of a time improvement in photo matching between the two.Continue

Launch with DJI Go, focus, then fly with UGCS

Started by Mark Fink. Last reply by Alexey Dobrovolskiy Aug 13. 12 Replies

I'm using a DJI Inspire 1 Pro and both the 15 mm and 25 mm lenses. Since DJI haven't made the ability to control focus available via their SDK, (apparently the beta version out now does!), I've been looking for ways to ensure I'm getting proper focus during photogrammetry missions. First, some background on what I've found with these lenses:The 15 mm lens, even when set to Manual on the lens itself, resets to some not quite at infinity setting each time you power on. So, for longer missions…Continue

I'm working on pixhawk with UgCS .Net SDK.I could connect to UgCS Server and receive telemetry values of the pixhawk.When I try to connect multiple pixhawk, I fail.UgCS connects to the latest pixhawk it detects and doesn't show the values of the first pixhawk.I also noticed using UgCS client that, telemetry values of 2 pixhawk connected are shown under the latest and not separately.In memory it still have both the pixhawk connected.I would like to know why I couldn't connect to multiple pixhawk…Continue

Telemetry Data received is Incomplete using UgCS .Net SDK

Started by Priya Sharmila. Last reply by Priya Sharmila Aug 10. 3 Replies

I started to work with UgCS client and server a couple of days back. I could create connection to the UgCS server and I could also subscribe to the vehicle to receive telemetry data. Problem is, When I receive the telemetry data, it is not complete.First Message I receive contains 10 telemetry type values. But later, I only receive ROLL, PITCH, HEADING.I tried to check the vehicle data using the UgCS example application and it happens there as well. Could anyone tell me why I couldn't receive…Continue

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.

Got reply back from UGCS on the use of tablet . Trying to find out whether pixhawk copter or fix wing is supported and working .

will work on the mobile tablet . All i could find was support for DJI . According to the email Android 5 and 6 is working ?
