If this product could record one more channel for GPS data- *exactly* in sync with the video data, that would be very useful.
Four very wide angle cameras, one front, one for each side and one for the back.
Maybe all four could be tilted up just a little bit so there was enough overlap to cover all of the sky.
If the frames could then all be in sync, you could have full 360 degree motion video with a geolocation data track as well. Then with a little trig, you could derive the geometry of everything you saw.
