The official ISRO page is up, launching on February 14 00:29 UTC from FLP.

2 other satellites will be on board.

2 other satellites are INSPIREsat-1 and INS-2TD.

According to ISRO, the rocket will also carry two small satellites as co-passengers. They include one student satellite (INSPIREsat-1) from Indian Institute of Space Science & Technology (IIST) in association with the Laboratory of Atmospheric & Space Physics at the University of Colorado, Boulder, and a technology demonstrator satellite (INS-2TD) from ISRO, which is a precursor to India-Bhutan Joint Satellite (INS-2B).

RISAT-1A/EOS-4 along with INS-2TD and Inspiresat-1 have been placed into orbit.

Congratulations ISRO on another successful launch of PSLV!

Very uplifting, encouraging achievement, particularly in the light of the struggles with Covid, and the huge setback of the GISAT-1 mission last August.

Mission Director SR Biju said "what we have accomplished today is really marvellous."

Was there anything specific about this launch/mission that makes it 'marvellous'. It's a fine achievement, and every space launch is a wonder in itself. One little anomaly can throw the whole mission off and cause a failure. Even with proven vehicles like the PSLV.

Is he referring to ISRO's recovery after the disheartening failure of the GISAT-1 launch, or the fact that ISRO could, in the time of Covid( which hit ISRO and its vendors pretty hard) bring together a large group of individuals and organisations to execute a highly successful launch? Or is it the launch plus the very sophisticated satellite EOS-4( Risat-1A), which did have technological hurdles to overcome?

DRDO Developed MMICs Onboard EOS 04

Defence Research and Development Organisation (DRDO) developed Monolithic Microwave Integrated Circuits (MMICs) have been used in radar imaging satellite modules of EOS 04, which was launched by ISRO on 14th Feb 2022. Many of the Monolithic Microwave Integrated Circuits (MMIC) were designed/ developed and produced at Solid State Physics Laboratory (SSPL) DRDO and Gallium Arsenide Enabling Technology Centre (GAETEC) foundry of DRDO.

The TR-Modules used in the payload for Radar imaging have been developed using these MMICs. More than 30,000 modules have been produced at GAETEC foundry for various space missions. This is an example of collaborative achievement between two advanced technology departments of Government of India along with support of industry partners. The use of indigenously designed and developed MMICs is an important step towards Atmanibhar Bharat.

EOS-04, INS-2TD and INSPIRESat-1: Update

ISRO launched EOS-04, INS-2TD and INSPIRESat-1 satellites on February 14, 2022 onboard PSLV-C52. All satellites are healthy and performing satisfactorily.

EOS-04: First Payload imaging was successfully completed on February 25, 2022. Currently, detailed in-orbit tests are underway. Radiometry, Geometric evaluation, Interferometric calibration, etc. are being carried out.

INS-2TD: A typical image received from Thermal Imaging Camera onboard INST-2TD is given here. This image captures part of Gujarat.

INSPIRESat-1: The Spacecraft was commanded by IIST ground station to switch on the Dual-aperture X-ray Solar Spectrometer. Initial analysis on the data downloaded indicates excellent resolution.
