CEOS Instrument: GPS Radio Occultation System

Instrument:GPSRO (Terra-SAR)
Agency: NASA
Mission: TerraSAR-X
Type:GNSS radio-occultation receiver
Description:Measurements of atmospheric temperature, pressure and water vapor content.
Spatial Resolution: N/A
Swath Width: N/A
Wavebands: N/A
Technology: GNSS radio-occultation receiver
Description: GNSS receiver equipped with directional antennas to receive the signal from one of the GNSS satellites during occultation, and measure the phase, thus the bending angle and the refractivity index profile. Simultaneously, a companion GNSS receiver provides precision positioning. The refractivity index is associated to temperature, humidity and density. The vertical resolution of the product can be as good as 0.5 m, the horizontal resolution is conditioned by the limb geometry (~ 300 km). Applicable only in LEO.
