EOS-04

EOS-04 or Earth Observation Satellite - 04 is an Indian [Space Research Organisation] Radar Imaging Satellite designed to provide high-quality images under all weather conditions for applications such as Agriculture, Forestry & Plantations, Soil Moisture & Hydrology and Flood mapping. It is a follow on to RISAT-1 satellite with similar configuration. The satellite is developed by the ISRO and it is the sixth in a series of RISAT satellites.

Satellite description

Synthetic aperture radar can be used for Earth observation irrespective of the light and weather conditions of the area being imaged. It complements/supplements data from Resourcesat, Cartosat and RISAT-2B Series. The satellite carries a C-band synthetic-aperture radar and has a liftoff mass of. The EOS-04 orbit is polar and Sun-synchronous at 06:00 AM LTDN, at approximate altitude of 529 km.
Assembly Integration and Testing of spacecraft was done by a consortium led by Alpha Design Technologies Ltd. Approximate cost of EOS-04 is.

Launch

EOS-04 was launched on the Polar [Satellite Launch Vehicle] from First Launch Pad, SDSC, SHAR, Sriharikota at 05:59 hrs IST on 14 February 2022. It was launched along with two ridesharing satellites, INS-2TD a technology demonstrator by ISRO and INSPIREsat-1 a university satellite.
EOS-04 captured first images on 25 February 2022 after launch.
