I’m back with bad news
I went out to finish the flight quickly before it rained, but a ‘Check mag field’ message appeared on the mission planner and I proceeded to calibrate the compass again. However, if the calibration is not completed properly and the gauge is full, it returns to zero and fills again.
Subsequently, only values with a magfield parameter greater than 4000 were measured. It was the same no matter how many times I re-calibrated (a total of 8 compass calibrations were performed).
The test site is conducted in a place where there is only a distance from metal and grass, so I judge that it is not a problem of location. It seems to be a problem with the structure of my drone.
I’ve never studied electricity or electronics, so I’m asking for help.
My drone is a DJI F450 aircraft, and I use a Pixhawk4 as an FC.
A ZED-F9P (RTK) module was used to connect to the Pixhawk4, and structurally stacked on top of the Pixhawk4. And the GPS antenna is located on it.
Pictures are attached for easy understanding.
The gap between the first and second floors and the gap between the second and third floors is 2 cm. Each layer is a plate printed by a 3D printer, and the component is PLA filament. A support such as a column is a plastic support made of nylon. (I used a metal support, but I had a ‘compass offset too high’ problem, so I changed it to plastic)
Is there a problem with this structure in the opinion of the majors?
I ordered the same support 50mm to see if it would be okay if I lifted it up.
How can I fly this drone…
I sincerely hope for your help.
