EOS-04 or Earth Observation Satellite - 04 (formerly known as RISAT-1A) 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.[3][4] 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.[5] It complements/supplements data from Resourcesat, Cartosat and RISAT-2B Series.[6] The satellite carries a C-band synthetic-aperture radar (SAR) and has a liftoff mass of 1,710 kg (3,770 lb).[2] The EOS-04 orbit is polar and Sun-synchronous at 06:00 AM LTDN, at approximate altitude of 529 km.[7]
Assembly Integration and Testing of spacecraft was done by a consortium led by Alpha Design Technologies Ltd.[8] Approximate cost of EOS-04 is ₹490 crore (equivalent to ₹550 crore or US$69 million in 2023).[9][10]
Launch
EOS-04 was launched on the Polar Satellite Launch Vehicle (PSLV-C52) from First Launch Pad(FLP), SDSC, SHAR, Sriharikota at 05:59 hrs IST (00:29 hrs UTC) on 14 February 2022.[6][11][12] It was launched along with two ridesharing satellites, INS-2TD a technology demonstrator by ISRO and INSPIREsat-1 a university satellite.[11]
EOS-04 captured first images on 25 February 2022 after launch.[13]
