INSAT-3DR is a weather satellite from the Indian ISRO from the Insat series. The satellite is the successor to INSAT-3D .
It was placed in geostationary orbit on September 8, 2016 at 11:10 UTC by a GSLV launcher from the Satish Dhawan Space Center rocket launch site.
The three-axis stabilized satellite is equipped with a six-channel imaging system, an atmosphere measuring device with 19 channels (18 infrared at 3.7 to 14.7 µm and one channel in the visible range at 695 nm) and a system of the international search and rescue system COSPAS-SARSAT and is to deliver meteorological data such as weather images and data on the distribution of temperature, humidity and ozone content of the atmosphere from its position 74 ° East . The data is transmitted via an antenna with a diameter of 11 m. The energy supply is provided by solar cells that deliver up to 1700 watts and (in contrast to INSAT-3D) lithium-ion batteries with a capacity of 90 Ah. INSAT-3DR was built on the basis of the I-2K satellite bus from ISRO.
Compared to INSAT-3D, INSAT-3DR can record images in the mid-infrared range, which enables images of low clouds and fog at night. Imaging in two thermal infrared regions enables the sea surface temperature to be estimated with greater accuracy. In addition, the spatial resolution in the visible and thermal infrared range has also been improved.
The first images were broadcast on September 15, 2016.
