Backpropagation Processing of GPS Radio Occultation Data
نویسندگان
چکیده
We provide an assessment of the backpropagation (BP) method for processing GPS radio occultations using simulations as well as recent data from CHAMP and SAC-C. It is found that BP gives improved retrievals over the standard Doppler technique, even when multipath ambiguities are not completely removed. In addition, by being an amplitude-weighted algorithm, BP is robust in the presence of receiver errors that arise when signals with low SNR are tracked.

Highlights 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...

First results from the GPS radio occultation experiment aboard the German CHAMP satellite are presented. The agreement between observed temperature profiles in the upper troposphere and the lower stratosphere and temperature profiles obtained from meteorological analyses is found to be below 1 K. The data processing and analysis system (operated by GeoForschungsZentrum Potsdam) has been success...

At the end of September 2009, a new Italian GPS receiver for radio occultation was launched from the Satish Dhawan Space Center (Sriharikota, India) on the Indian Remote Sensing OCEANSAT-2 satellite. The Italian Space Agency has established a set of Italian universities and research centers to implement the overall processing radio occultation chain. After a brief description of the adopted alg...

[1] Global Positioning System (GPS) radio occultation (RO) is a space-borne remote sensing technique providing accurate, all-weather, high vertical resolution atmospheric parameters, including pressure, temperature and humidity in the troposphere and stratosphere. In the moist lower troposphere (LT) RO encounters known problem related to the phase-locked loop (PLL) tracking technique applied in...
متن کاملAtmospheric Remote Sensing Data Processing Through Grid Computing Technique
The space-based GPS limb sounding, conventionally known as GPS Radio Occultation, is a remote sensing technique aiming at characterize the Earth atmosphere. The atmospheric profiling is done through the inversion of excess-phase measurements carried-out by a GPS receiver placed on-board a LEO (Low Earth Orbit) satellite. The GPS signal, observed when it emerges from the Earth limb, is refracted...
