Solid Booster Test back in 2010:

https://spacenews.com/india-successfully-conducts-static-test-of-its-largest-solid-booster-s200/

Indian Space Research Organization successfully conducted the static test of its largest solid booster S200 at Satish Dhawan Space Centre (SDSC), Sriharikota today (January 24, 2010). The successful test of S200 makes it the third largest solid booster in the world, next to the RSRM solid booster of Space Shuttle and P230 solid booster of ARIANE-5. The S200 solid booster will form the strap-on stage for the Geosynchronous Satellite Launch Vehicle Mark III (GSLV-Mk III) which is currently under advanced stage of development for launching 4 ton class of communication satellites.​

S200 solid booster contains 200 tonnes of solid propellant in three segments. The motor measures 22 meter long and 3.2 meter in diameter. The design, development and successful realisation of S200 solid booster were a pure indigenous effort involving Vikram Sarabhai Space Centre, Thiruvananthapuram and Satish Shawan Space Centre (SDSC) at Sriharikota with the participation of Indian Industries. The S200 solid booster derived its heritage from the solid boosters developed earlier for the ISRO launch vehicle programme. The preparation and casting of S200 solid booster segments were carried out at the newly established Solid Propellant Plant (SPP) at SDSC, Sriharikota.​

During the test, the S200 booster was fired for 130 seconds and generated a peak thrust of about 500 tonnes. The performance of the booster was exactly as predicted. Nearly 600 health parameters were monitored during the test and the initial data indicates normal performance.​

Todays successful test of S200 is a major milestone in the solid rocket motor programme of ISRO and a vital step in the development of GSLV Mk III.​

November 2022:

Successful CE20 uprated Engine Hot Test with 21.8 T vacuum thrust


Successful CE20 uprated Engine Hot Test with 21.8 T vacuum thrust The CE20 cryogenic engine indigenously developed for LVM3 has been subjected to a successful hot test at an uprated thrust level of 21.8 tonnes for the first time on November 9, 2022. This will enhance the LVM3 payload capability up to 450 kg with additional propellant loading.

The major modification carried out on this test article compared to previous engines was the introduction of a Thrust Control Valve (TCV) for thrust control. In addition to this 3D-printed LOX and LH2 turbine, exhaust casings were inducted into the engine for the first time. During this test the engine operated with ~20 t thrust level for the first 40s, then the thrust level was increased to 21.8t by moving the thrust control valve. During the test, engine and facility performance was normal and the required parameters were achieved.
