When I fly indoors in my living room the P3 will not hold position. I have the quad in GPS P mode. It is seeing 11 sats.
I thought the bottom facing camera & ultrasonic sensors were supposed to hold the position. Instead it will drift around in a 6 foot radius. It also does not hold altitude. I have a hardwood floor with wool rugs with very distinct (high contrast) non repeating pattern. The position detecting camera should have no issue seeing contrast on the floor.
I have Firmware 1.1.9 loaded in the P3 and 1.1.8 loaded in the controller. I am running 1.1.1 for iOS on iPad Air 2.
So what is the downward facing camera & ultrasonic sensor supposed to do?
Both patterned carpet and wood. It can't even hold position over the corner of the carpet boundary with the hardwood. And my Harwood floor is a very light color with dark wood grain knots...
There is plenty of non-repeating objects for the camera to lock on.
I just had the same issue on my maiden flight, i panicked and landed straight away ill wait until tomorrow when im outdoors i almost flipped it on its side when putting it back down - Adam
Yea....this caused my first and only crash so far. Luckily it was into a padded couch and padded carpet so nothing was damaged except a few minor marks on the props. I don't trust it inside, but outside it is like a dream.
It needs a lot of light to work well. The first time I tried it it did drift a bit, but the light wasn't that good. The second time I tried there was lots of light and it held position perfectly.
I'm having the same problem with drift inside. I was shooting a church with the lights on, mid morning, and stained glass windows. Plenty of light. It does have carpet. Is there any adjustment that can be made on the PH 3? Could it be a flaw in the blades or a difference in motor speed at idle?
When you are flying indoors or in places with bad visibility of the sky you should fly the Phantom (does not matter which version) in attitude not GPS because in such places the signal from the satellites arrives at the receiver bounced several times causing a noisy / erroneous positioning making the drone believe that is moving when in fact is not.

I've the had the same problem and found this great tutorial on the phantom 3 pilot app. Re-calibrating the IMU fixed the problem for me. Here is the YouTube link to the tutorial. This turtorial should be a must for every new Phantom pilot.
That was a GREAT Review of the DJI Pilot App. I wish I had seen this when I first got my aircraft. However, I did learn some additional things by watching your video. Thanks
Thank you @challenger451, the video was helpful and showed me a couple things I was unsure about.
I look forward to watching it again when I receive my Phantom 3 Professional, likely this coming Monday...
Later firmware updates have taken car of most of this issue. But I have found the visual positioning system needs bright light and plenty of contrast on the floor to function at all. Dimly lighted interiors just don't work. Frankly... I fly in ATTI mode indoors. Don't trust the computer indoors. I would rather fly manually.
