CEOS Instrument: Radio Occultation Sensor for Atmosphere




Instrument:ROSA
Agency: ISRO
Mission: MEGHA-TROPIQUES
Status:Operational
Type:GNSS radio-occultation receiver
Description:Enables measurement of water vapour and temperature profiles in the tropics
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.
