Kalpana 1



Kalpana 1 (formerly Metsat 1) is an Indian (ISRO) meteorological, geostationary satellite that was launched by an upgraded, four-stage PSLV-C4 rocket from Sriharikota in the southeast coast of India at 10:24 UT on 12 September 2002. The triaxially-stabilized, 1,050 kg (including 560 kg of propellant), 550 W satellite carries a VHRR (Very High Resolution Radiometer) scanning radiometer for three-band images: one in the visible, the second in the thermal infrared and the third in the water vapor infrared bands, each at a spatial resolution of 2-km x 2-km resolution, to obtain atmospheric cloud cover, water vapor and temperature. It carries also a Data Relay Transponder (DRT) to provide data from fixed/mobile ground level weather platforms. It was maneuvered from the transfer orbit to a geostationary at 37 degrees E longitude on 16 September, and then to the final parking at 74 degrees E longitude on 24 September.

The satellite was renamed in honor of Kalpana Chawla, the Indian astronaut who died in the Space Shuttle Columbia accident in February 2003.
