Short answer:

yes, you need a GPS.

slightly longer answer:

You need something that can give you a position (like indoor tracking system).
Or at least something like an optic flow sensor...

Short question:

While in on of the "AP_MODE_HOVER_*" modes, does the rotocraft need GPS
input to hold the horizontal position or does it have enough information
from the accelerometer(, magnetometer) and gyro alone? Or, to put it in
another way: Can I let it hover in a large indoor area?
