Nice work. That's a strange location - it's not on an RTH route. It's unfortunate that we can't read the aircraft DAT files from the M2 to figure out what it was doing.

Could the controller have taken over the RTH with some movement from the sticks or was this a complete signal loss?
Some cool software sar104 is using to pick out that stick in the woods.
Edit; Lucky it went down the hill and not the other way, up into it
IMG_20181106_105412.jpg is the best Mavic photo I've seen on here so far
Congrats

OK - so it just missed the tree that I pointed to and then lost connection, rotated to retrace path and was blocked. The subsequent sideways movement is unexplained. Then it looks like it auto landed due to low battery.
Your data analysis was spot on all things considered. It's funny because it looked like it was trying to decide how to get around the tree then it's like it gave up after awhile and darted to the right as if it was frustrated. Obviously it can't get frustrated but was interesting to see it's movements.
Thought the same exact thing, it 'appeared' frustrated. lol
Yes - it did seem like that. If it had done that earlier it would have had enough battery reserve to get home.
Thank you! It looks perfectly fine in the visible hardware, but I´ll try it out again in a couple of days

Nice job Sar, this forum is lucky to have you
Thanks, but I was really no help at all on this one - the OP found the aircraft by luck. I'm still rather mystified by its behavior.

My thoughts are, from Just going on what is observed in the video;
As it avoided the 1st tree (obstacle) it proceeded only to be met by a 2nd one, but by this time the battery was depleting and it dropped to the height of ground level (landing sensor detected this and hovered, but it wasn't flat) preparing for auto land, although in this case seemed to be the hillside.
Sensing that as an obstacle it veered to the right until the ridge was out of sight, though at that moment the auto land took over and the rest is history.

looked like it was "confused" for lack of a better term, on how to get around the top of that tree...would the RTH keep it from going over the set height if it is trying to avoid an obstacle? what i mean to ask here is ..if RTH is set to 30m and the tree is 31m high, would the drone raise up to 31m to get over it or would it be stuck at 30m trying to figure out how to get around the obstacle?

The craft was already at the maximum height set
They have some tall trees up there.
The battery was near depleted after trying to work its way around the hill and the sticks on it.
We'll never know for sure.
You're making a situation up, which I'm not sure of the best way to reply.
There was no HEADROOM!
Or your saying I'm making up what I interpreted.

Just looking at the video, it looked like it couldn't figure out how to get around the tree. My thought was ..could it be stuck at the max RTH height and unable to rise to the height it would need to be at to get over the top of the tree. The question was..Does RTH allow for a drone to rise over the set ceiling height to get over obstacles?
but no, not saying you made up anything, just wondering if the programming allows for it to go over the set RTH height if something is in the way.

Yes, it would, if there is headroom between the obstacle and the max height set.
I see what you mean and has got me querying it now.
It is mentioned in the manual.
Now s'one will slap me for misquoting what I read once and forgot.
Edit; the sun can play havoc with this anyway. Though in this case it was behind the camera on RTH path.
this guy gives a rundown unless they changed it for the 2
