Abstract

The flight test technique described uses controlled survey runs to determine horizontal atmospheric pressure variations and systematic altitude errors that result from space-positioning measurements. The survey data can be used not only for improved air-data calibrations, but also for studies of atmospheric structure and space-positioning accuracy performance. The examples presented cover a wide range of radar tracking conditions for both subsonic and supersonic flight to an altitude of 42,000 ft.
