NASA Tests Flying Airbag 118

coondoggie writes "NASA is looking to reduce the deadly impact of helicopter crashes on their pilots and passengers with what the agency calls a high-tech honeycomb airbag known as a deployable energy absorber. So in order to test out its technology NASA dropped a small helicopter from a height of 35 feet to see whether its deployable energy absorber, made up of an expandable honeycomb cushion, could handle the stress. The test crash hit the ground at about 54MPH at a 33 degree angle, what NASA called a relatively severe helicopter crash."

I've implemented a couple of interesting wide area tracking systems in the past and have reasonable expertise on the various technologies involved.

RF solutions will not work indoors to the accuracies that you require (1ft). Too many problems with multi-path.

Vision-based solutions can be implemented, but robust commercial versions are expensive.

If you can dot the ceiling with paper targets and survey them, then use the new IS1200 from intersense (or contract them for a custom 2D version of their vision system without the IMU) (15k per tracker now, price should come down).

Laser-based systems would also usable. Try ArcSceond's constellation 3DI product.
