I have a question about the GPS/Compass (3DR). In general, when I open QGroundcontrol station and I go to mission plan, I can see that the GPS position is not accurate, it is jumping even several meters from the position of the Drone.
I am using Jetson TX2 and the GPS is quite close to it. I read that the USB3 port of the Jetson can cause disturbances in the GPS. Could be this the problem?
More technically.
I have QGC-Station and fly-mission-plan, when i set up all the points and I load the mission, I get the error ‘Unable to start mission (‘vehicle not ready’)’.
In other words,
I have tried position control and the drone responded quite satisfactorily using the RC transmitter. However, when I want to try fly mission mode, I can see that the GPS position is jumping even though the QGC takes up till 9 satellites, and the GPS is locked and the HDOP < 1.5 and the VDOP < 1.5.
I can chose the way points and load the program but when I want to change to mission and arm I get the error: I get the error ‘Unable to start mission (‘vehicle not ready’)’.
Secondly:
Well, I read that USB3 is known to be an effective GPS jamming source. So, I have wrapped under the GPS and between the USB3 from Jetson TX2. And, amazingly The GPS status was as follows:
GPS Count 17
GPS lock 3D DGPS lock
HDOP 0.7
VDOP 1.1
Course over ground 219.4
However, when I set up or add way points in mission plan. I could successfully load the mission and when I wanted to start the mission I got the same error:
““Unable to start vehicle not ready”” Even though I tried few times just one log file is available.
I read that the log files only generates when the drone is armed and disarmed, right? well, in that case I armed and disarmed the drone once with the RC-controller.
But, the question is: How can get the log file if it does not allow me to arm and start the mission planer flight mode.
I have the link that has been generated by the flight review.
Also, after I loaded the first mission plan and failed. I set up new mission plan and then when I wanted to load the way points mission, I got the error: ““Mission write failed to send final ack.””
