Not progressing to waypoints

Started by Keith Conley. Last reply by Artūrs Jan 25. 3 Replies

Hello all,I'm looking to find some help with figuring out what I'm doing wrong with my UgCS missions. I'm hoping someone can look at the mission and tell me what I'm doing wrong.I've been able to create a mission, connect to the drone, upload the mission to the drone and send the drone on its way. It reaches the first waypoint and then stops and just hovers in place. The drone does no other action until I hit the return to home button on the controller. I'm using a DJI Phantom AdvancedMy route…Continue

Yaw/Pitch control with Lightbridge 2 + A3

Started by Robert Matthews. Last reply by Robert Matthews Oct 15, 2018. 2 Replies

Hello,We are using a DJI M600 with a Ronin MX gimbal and an Android tablet.When using the DJI app we can select between making the gimbal yaw and pitch using the C2 button on the controller, you then use the dial to move the gimbal. If we then switch to the UgCS app the C2 button will not switch between giving you yaw or pitch control, it will just be set to whatever the last setting was when using the DJI app. Is there a way to swap between having yaw/pitch control while a mission is being…Continue

Error with many waypoints

Started by Thomas Stanley-Jones. Last reply by Anna Moshkova Sep 28, 2018. 1 Reply

I get this error when I'm planning very large missions (more than 1200 waypoints approximately) and trying to pair them down to a manageable size.Once I get this error, I'm unable to remove routes from the program since they show up again after about 30 seconds.  I also can't edit the waypoints either since changes are not saved…Continue

Add drape waypoint functionality

Started by Thomas Stanley-Jones. Last reply by Alexey Dobrovolskiy Sep 24, 2018. 1 Reply

When AreaScan is used, UgCS places extra waypoints to keep the flight path at a constant altitude above ground level.  However, once the route is converted to waypoints, this functionality is lost.  There needs to be a way to either convert the waypoints back to a route so the draping can happen again, or have a command to apply drape to segments.  This would command UgCS to add waypoints along the segments to maintain height above ground.I've also needed this when I import a CSV of endpoints,…Continue

Areascan with Basepoint

Started by Thomas Stanley-Jones. Last reply by Alexey Dobrovolskiy Sep 24, 2018. 5 Replies

I need to do scans over a large area (not a camera) and I need the lines from each block to line up together.  Is there a way to create an areascan mission with a basepoint?  This way, all the lines will start from a common location.  The basepoint needs to be able to be somewhere not in the survey area.Continue

Multiple Waypoint Selection

Started by Thomas Stanley-Jones. Last reply by Alexey Dobrovolskiy Sep 22, 2018. 8 Replies

Is it possible to select multiple waypoints?  So far I have only found a way to select all the waypoints, or only 1.  This makes it very awkward to edit a large plan, but I'm hoping there is a feature I'm missing, like a select tool.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.
