Just In: India's advanced weather satellite INSAT-3D has been successfully launched from the space-port of Kourou in French Guiana

INSAT-3D is designed to provide meteorological observation and monitoring of land and ocean surfaces. In addition to the sounder, the satellite is equipped with a six-channel imager, a data relay transponder (DRT) and a payload for satellite-aided search and rescue operations. 

INSAT-3D adds a new dimension to weather monitoring through its atmospheric sounding system, which provides vertical profiles of temperature, humidity and integrated ozone from surface to top of the atmosphere. 

The imaging system of INSAT-3D has significant improvements over that of KALPANA and INSAT-3A, the space agency said. 

INSAT-3D will provide continuity to earlier missions and further augment the capability to provide various meteorological as well as search and rescue services. 

INSAT-3D also carries the newly developed 19 channel sounder, which is the first such payload to be flown on an ISRO satellite mission.
