Sriharikota: India’s Polar Satellite Launch Vehicle PSLV-C52 injected Earth Observation Satellite EOS-04, into an intended sun synchronous polar orbit of 529 km altitude at 06:17 hours IST on 14 February 2022 from Satish Dhawan Space Centre, SHAR, Sriharikota.

PSLV lifted off at 05:59 hours IST from the first launch pad at SHAR. This was the 80th launch vehicle mission from SDSC SHAR, Sriharikota; 54th flight of PSLV; and the 23rd flight of PSLV in XL configuration (6 strap-on motors).

The satellite EOS-04 is realised at U R Rao Satellite Centre, Bengaluru. It is a 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. Weighing about 1710 kg, it generates 2280 W power and has a mission life of 10 years. 

Congrats my friend Somnath. You have brought ISRO back on track after very disappointing two years, with Valentine Day tryst of PSLV C – 52 launch. It could not have been better that this launch carried EOS-4 a la RISAT-1A, a C-band SAR satellite dear to me.

I wish RISAT-1A had the high resolution mode of 0.7 m like its predecessor RISAT-1. In the present satellite, the resolution is limited to 2 m. Nonetheless, RISAT-1A will prove to be a great asset in many civilian applications like its predecessor proved to be. – Tapan Misra, Distinguished scientist, former Director Space Application Centre and father of Indian SAR (Synthetic Aperturre Radar)


The vehicle also placed two small satellites a student satellite (INSPIREsat-1) from Indian Institute of Space Science & Technology (IIST) in association with Laboratory of Atmospheric & Space Physics at University of Colorado, Boulder and a technology demonstrator satellite (INS-2TD) from ISRO, which is a precursor to India-Bhutan Joint Satellite (INS-2B). Co-passenger satellites were successfully separated from the PSLV in a predetermined sequence.

Secretary Department of Space and ISRO Chairman S Somanath has congratulated team ISRO for the precision with which the mission was accomplished.
