I lost my Mavic Pro Platinum.

Which UAV forecast app do you recommend?

That is the name of the app. Check www.uavforecast.com

Just curious, did you have any idea that you are not supposed to fly above 400 Above ground level? You really should just read this forum every day - great source of knowledge

Takeoff from a magnetically compromised location is not a malfunction of the drone, nor is the resulting switch to ATTI mode.

The takeoff point was not magnetically compromised.

When I lost the drone it had connection to satellites and had gps signal, so DJI should know where it landed right?

No - because the only way that the flight data gets to DJI is via your mobile device, when you sync the logs.

So basically what you are saying is that the drone had a malfunction which caused it to start drifting?

No - well possibly, but not likely. Most likely is that you launched from a location with magnetic interference. If you look at the detailed magnetometer and gyro data from the DAT file that you posted, the problem is fairly clear:



This shows both flights on that power cycle. Notice that on power up the IMU yaw value is initialized by the compass yaw value, but then the compass value deviates significantly on takeoff, even though the z-axis gyro doesn't record any rotation. That's very suggestive of magnetic interference, but it could also be a compass or IMU calibration issue. Were you wearing anything magnetic while handling it just after power up? Here's a close up of the first few seconds after power up:




After that the aircraft is operating marginally due to the incorrect initialization.

I took my drone off from inside my garage so that must be why.

Yes, I did. I was stupid of me to fly so high especially since it cost my drone.

You obviously need to learn a lot more about drones. How could you make the statement about the takeoff point not being magnetically compromised when you really had no idea as to whether that was true. For one thing, if your garage floor is concrete, it may well have rebar in which does magnetically compromise the drone.

So there is no way DJI can track it with GPS or satellites.

You are right.

There is only one.

That's likely the cause.

That is the name of the app. Check www.uavforecast.com

App name is “UAV Forecast” without the quotes

Ok, thank you!

Well you are experiencing a steep learning curve Hope you find your drone.

Thank you! I will find it!

I appreciate y’alls support!

So you ran the thing up to 300 meters, close to a thousand feet, and eventually to 500 meters. Did you read about the 400 ft (not meters) legal flight ceiling?
Karma, quick and clean.

Quick question from a fellow newbie....did you calibrate the compass before takeoff?

There is no need to calibrate the compass before flight.
Not calibrating before flight won't make any difference to anything.
Unnecessarily recalibrating the compass won't make the flight any safer.

Because takeoff was in the OP's garage, it's not likely that would have had a positive effect; a magnetically compromised location will mess with the compass full stop.
