ISRO has successfully launched its advanced weather satellite INSAT-3DR. The GSLV-F05 took off from Sri Harikota and successfully installed the INSAT-3DR into its orbit. INSAT-3DR is an advanced meteorological satellite that has been configured with an imaging system and an atmospheric sounder. INSAT-3DR had a lift-off mass of 2211 kg, which includes about 1255 kg of propellant. The propellant carried by INSAT-3DR is mainly required to raise the satellite from the Geosynchronous Transfer Orbit (GTO) to its final Geostationary Orbit and to maintain the satellite in its orbital slot during its life, says ISRO.

GSLV-F05 is the flight in which the indigenously developed Cryogenic Upper Stage (CUS) will be carried on-board for the fourth time during a GSLV flight. GSLV-F05 is significant since it is the first operational flight of GSLV carrying Cryogenic Upper Stage.

INSAT-3D was launched by ISRO in 2013, and it had added a new dimension to weather monitoring through its atmospheric sounding system. INSAT-3DR, the latest meteorological satellite built by ISRO, is similar to INSAT-3D. The improvements incorporated in INSAT-3D are also a part of INSAT-3DR. According to ISRO, these are:

  • Imaging in Middle Infrared band to provide night time pictures of low clouds and fog
  • Imaging in two Thermal Infrared bands for estimation of Sea Surface Temperature (SST) with better accuracy
  • Higher Spatial Resolution in the Visible and Thermal Infrared bands

INSAT-3DR carries a Data Relay Transponder as well as a Search and Rescue Transponder, like its predecessor. INSAT-3DR will provide service continuity to earlier meteorological missions of ISRO, the space agency says.
