Indoor Flying Altitude Limit is 13 feet AGL

[beatnik]

I had not flown indoors in a while. I was asked to fly over some RV's parked in a large hanger building. No GPS and the Mav in Atti. When I take off I get the warning NO GPS Altitude limit set. So it puts that limit at 13 feet. The ceiling in the hanger is about 50 feet. The RV's are about 8 feet-10 feet. Ugh. Any way around this very stupid limit? I understand they want to GEOfence NFZ with GPS, but there should be a way to bypass this indoors or at least set a reasonable altitude. I thought about climbing up on top of and RV to launch. Would that then give me 13 feet above the roof?

Might work launching at higher point.

Go outside, let it find a GPS signal, then go back in. Or disable the bottom sensors.

As in the two ultrasonic sensors? How do you disable them? Gaff
tape?
