The TAOSF aerostat observation platform. The photo on the left shows the aerostat, which is an unmanned, lighter-than-air (LTA) unpowered blimp on a tether. Helium is used for buoyancy. The gimballed TAOSF observation platform avionics package is shown on the right. It includes a GPS, a barometric altimeter, a magnetic compass, a serial wireless data link, a wide-angle color camera, and a video transmitter.
