摘要

An experiment to collect bistatically scattered GPS signals from a balloon at 37 km altitude has been conducted. This was the highest altitude to date that such signals were intentionally recorded. The flight took place in August 1999 over the Mediterranean sea, between a launch in Sicily and recovery near Nerpio, a town in the Sierra de Segura, Albacete province of Huelva, Spain. Results from this experiment are presented, showing the waveform shape as compared to theoretical calculations. These results will be used to validate analytical models which form the basis of wind vector retrieval algorithms. These algorithms are already being validated from aircraft altitudes, but may be applied to data from future spacebourne GPS receivers. Surface wind data from radiosondes were used for comparison. This experiment was a cooperative project between NASA, the Institut d'Estudis Espacials de Catalunya (IEEC) in Barcelona, and the University of Colorado at Boulder.
