Series.
The satellite carries a
C-band synthetic-aperture radar (SAR) 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

(PSLV-C52) from First Launch Pad(FLP),
SDSC, SHAR, Sriharikota at 05:59 hrs
IST (00:29 hrs
UTC) 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.
