Abstract:

Gravity measurements from a high-altitude balloon were made in October 1985 to verify global and upward-continued gravity models. This was the second flight in a series, and was intended to 1 test the use of differential GPS tracking and 2 measure gravity at altitude. A balloon operates in a largely unpredictable environment, where little, if any ground truth data are available. The motions of the balloon must be very accurately accounted for in gravity estimation. The experimental package contained a full complement of inertial sensors, radar transponder, a GPS receiver, and gravimeter. The first flight in October 1983 showed that tracking was the most difficult problem the second flight included differential GPS tracking to overcome that problem. The flight was successful with GPS tracking and gravity measurements. Keywords Global positioning system Gravimetry.
