How to get last Mavic Pro coordinates

[Matush]

Hello,

During last flight a lost connection to Mavic. However, it was lost communication between remote controller and phone, but I not realized it and thought that it was standart situation. When I understand that Mavic not initiate RTH it was too late. Mavic did automatic landing somewhere in the forest.

My question is how can I get latest Mavic GPS coordinates to be able fo find him.
Flight records from phone is not actual, because phone not recorded any Mavic position after connection lost.
I will be appreciated if you can provide precise coordinates from Black Box records if it possible.

Flight Record - DJIFlightRecord_2018-05-26_[16-39-53].zip
Black Box - BlackBox.zip

Thanks!

start looking on this area!!!

 

[Matush]

Thank you for response. However it is a very big area. It would be not problem if it was grain field or something flat. But it is a very dense forest...
I also tried to figure out precise coordinates. Here is my thoughts:
1. I have last coordinate and distance from phone logs: 443m distance and Lat,Long
2. I have a starting point from which this distance calculated
3. I look into fatal.log from remote controller and found last info from mavic - 419m distance and 22m altitude
4. I use previous Mavic fly direction and intersect it with 419m radius

So i expect that Mavic lands somewhere at location on this map:
However still not able to find him. So I assume that my calculation is wrong or Mavic holds somewhere on the top of the tree or someone already finds my Mavic before me
In any case i will happy any help from you or other guys. Thanks!

you could be right on that arrow line ... but wind dragged her more further along that line !! i hope you can get her back ...wish you luck

Last recorded location was 48.974861, 24.743581. It was heading NW under full forward elevator. The wind was not strong enough to prevent location hold, so where it ended up depends on whether you continued to provide stick inputs after the app disconnect, since the RC was presumably still connected to the aircraft.

Hi sar104,
I think you post incorrect coordinates because it is start point location, not last one.

Hi sar104,
I think you post incorrect coordinates because it is start point location, not last one.

Apologies for that - I've no idea how that happened. It should be 48.970929, 24.742711.

 

[Matush]

Hi again!

Thank you guys for support.
I found Mavic at 2m near point that I calculated.
I hope this experience and last location calculation approach would be helpful for someone else in such cases.



Thanks!

glad you found her no snake ?

The last Mavic video was corrupted but after few hours of trying different apps I fixed it.
I was surprised how Mavic landing and trying to avoid trees collision

That was super interesting. Its as if the Mavic was saying - "whoa, whoa, whoa, I dont want to hit the tree's but I have to land" It just hung there in the air for a while. Its almost like artificial intelligence.

Glad you recovered your bird!

upload your flight record!!!

 

[rodrigocoelho]

It clearly doesn't contain any coordinates.

Not directly, not lat/lon, but maybe a relative position.

Hi, does someone knows what means that info on fatal.log? Is it GPS coordinates. Drone direction can be estimated from there?

Go to DJI Flight Log Viewer - Phantom Help
Follow the instructions there to upload your flight record from your phone or tablet.
That will show you a detailed report.
Come back and post a link to the report it provides.

I don't have that log, since the RC lost communication with the phone. So, I only have the fatal.log

Already know the distance from home when started landing, but don't know the exact position.

I did some circles considering the distance as radio, but didn't find it.
Any help?

Unless if you lost communication before you launched, you should have a .txt file in your app.
If you want any help you'll have to find it because whatever it is that you posted, isn't any help to anyone.

I'm sending the log. It was recorded on litchi.

When I lost the video, I started the return to home. It started ok, but, after some time, started landing. After that point, I'm lost.
