I was under the impression that we had to leave GPS "ON". In my test, it was left on, and showed IPS. I am now wondering if I need to turn it off. That's why I received the calibration error and such..
From what was said above, OA needs to be off while flying indoors. I experienced that same behavior. When you see IPS active, it's using the sensors from RealSense to keep it stable.
You can turn on OA while in all modes (Smart, Angle, and RTH.). It's documented before you initiate RTH, to turn off OA, initiate RTH, and then turn on OA. Maybe why I received the OA error is due to only having the ability to hover a few feet off the ground and I kept my landing gear down (For emergency landing).
@Tree, was your landing gear up? What height were you hovering at?
Looks like I need to do some more testing in my garage with GPS off to see if that helps. When I made any lateral movement, it was very jerky (Even in turtle mode), and it did drift at times that I had to compensate for.
I did some research on Indoor Flying before I even tried to fly indoors, and even then the first time I tried, I forgot to turn off GPS, and this was before I had my RealSense installed. **** thing took off like an angry bird sideways at full speed along the floor. Luckily I was ready and cut the power immediately. Disaster averted.
I am new to the Typhoon H. But after I installed my RealSense, I went back to this 175,000 sq foot ware house where I am going to be filming, turned GPS off, was able to start the rotors indoors, noted that IPS was active, and crossed my fingers and lifted off.
The Typhoon hovered perfectly and did not move an inch. The only issue I had was about 20 feet up, when I went over by the docks and these industrial heaters kicked on and were blowing a healthy gust at my bird.
But that only moved it just a bit. So in my opinion the IPS works really great.
I have not tested Obstacle Avoidance, but this is North East Ohio, and I prefer to do something like that outside when the weather breaks. From what I have learned the last couple days, OA is strictly for outside.
So here is my advice from a Novice using a Typhoon H and flying indoors.
Make sure in settings you have RealSense checked as installed.
I had my Typhoon in Advanced Mode On.
I then went Home to the Flight Screen, and then went to Calibration settings and turned GPS off.
I had OBS toggled off on the ST 16.
I had The Typhoon in Angle Mode.
I had the Typhoon in Turtle Mode.
The Typhoon flew perfectly indoors, and I was impressed with it's stability.
It was flipping stressful as **** though flying indoors, and trusting everything I read, and some of what I learned on here.
But I think OBS off, GPS off, and making sure you see the ST 16 show IPS active, and you are ready to fly indoors.
I am not even sure you can start the rotors if you don't have things set up right.
