Atmosphere sounding using GPS radio occultation
Introduction On July 17, 1995 the U.S. Air Force announced “ .. that today the Global Positioning System (GPS) satellite constellation has met all requirements for Full Operational Capability”. Apart from precise positioning GPS signals also can be used to derive characteristic properties of the propagation medium (neutral atmosphere and ionosphere). Onboard the Low-Earth-Orbiting MICROLAB-1 sa...

Fig. 1. The German CHAMP satellite (view from antivelocity direction with GPS occultation antennas) Abstract: The German CHAMP (Challenging Minisatellite Payload) satellite (launched on July 15, 2000) is a geoscience mission aiming for the determination of Earth’s gravity and magnetic field and for GPS-based atmospheric sounding. The atmospheric profiling experiment onboard CHAMP was started in...
متن کاملHighlights of Gps Radio Occultation with Champ ( Neutral Atmosphere )
The atmosphere sounding experiment of the German CHAMP (CHAllenging Minisatellite Payload) satellite mission was activated on February 11, 2001. Since then more than 110,000 occultations were recorded as of mid-December 2002. The results of nearly two years CHAMP GPS (Global Positioning System) occultation measurements and data analysis have shown, that significant improvements of the GPS radio...

متن کاملStatus of GPS radio occultation with CHAMP
The German geoscience satellite CHAMP (CHAllenging Minisatellite Payload, launched on July 15, 2000, Reigber et al., 2002) is in orbit now for more than 2 years. CHAMP's measurements are used to determine Earth's gravity and magnetic field and to derive precise information about vertical temperature, humidity and electron density distribution on a global scale using the innovative GPS radio occ...
