The space organisation will carry out four crew-escape demonstration missions as part of a series of tests to make Gaganyaan safe for manned flight ...
QuoteIsro chairman S Somanath said, “The vehicle for testing the crew abort mission is ready. It is a new rocket. We call it a test vehicle. The test vehicle with a crew module and crew escape system will go through a test demonstration. We will repeat it once again this year. After that we will be doing unmanned missions most probably mid-next year. Four escape demonstration missions are planned to prove that crew can escape in case of an anomaly. After that there will be one more unmanned mission before a manned mission is launched.”

ISRO plans Gaganyaan test demonstration by December
The Indian Space Research Organisation (ISRO) has planned to launch the Gaganyaan test vehicle for a crew abort mission this year, its Chairman S. Somanath said here on Saturday.
“Several tests are under way for crew module, crew escape system, electronics, intelligence, software at many centres. We are developing a crew module, a training module, astronaut training, display systems, crew training facilities and simulators. This year, we aim to demonstrate a crew escape system, which is the first step. Next year, we will do an unmanned crew mission and recover the module. Then we will again test crew escape systems two times with improvements based on observation. Currently, we are targeting a human space flight in 2023,” he said during his visit to the Karunya Institute of Technology and Sciences. -

Gaganyaan abort test: Vehicle to go up to 11km, crew module around 15km
BENGALURU: The first abort test using the special test vehicle (TV) as part of Gaganyaan will see the crew module separate from the TV at a height of around 11km (from sea level), attain an altitude of around 15km before falling back to back in the Bay of Bengal.QuoteA senior official overseeing the mission, told TOI: “We’ll take the vehicle to around 11km approximately and then from there, the crew module will go up to about 15-16km and then it will come down. We’ll demonstrate the coming down, descent phase, parachute deployment and recovery.”
Quote“...We are looking at integration next month, following which there will be extensive testing before the TV-TD1,” he added.
Quote“We’ve developed three types of simulators that will help them (astronauts) get familiar with the cockpit, crew module controls, mission profiles and experiences, etc. They will also have simulations for manual intervention if any. Aside from this, there are other simulators on the anvil depending on the progress,”
QuoteIn TV-T1, Isro will intentionally cause an anomaly and allow the crew module to come out of the TV, do the tumbling manoeuvres, deploy parachutes, and land in a designated spot on the sea before being recovered.

“Astronauts are undergoing training and they are back from Russia. In the next one year, they will be undergoing many theoretical, experimental, simulation activities and will be trained in specific skills related to the mission… There was an important crew module and propulsion module test that was conducted recently. We are also planning to do a revised crew abort system—a process of aborting the mission in case of an emergency—using a test vehicle which will be flagged off to Sriharikota for launch in two or three days. We hope that all our tests will go successfully and be able to meet the target by the end of 2023,” said Somanath.

ISRO expo in Bengaluru: Perfect weekend getaway for space enthusiasts to learn about Gaganyaan, human spaceflight
QuoteAn ISRO engineer, who demonstrated the crew module, said the astronauts will be in a curled position – or fetal position – with minimal movement.
Prior to the descent, at one point in time, the service module will be separated from the crew module because of the need for weight optimisation. Using parachutes, the crew module will land in the Indian waters.
Once the crew module lands in the ocean, it will be recovered through a joint operation of the Indian Air Force, the Navy and the Coast Guard.
After the touchdown, the ISRO engineer said, the crew will be subject to the rehabilitation of 1-2 weeks, which is still being deliberated, in one of the ISRO facilities as their bodies will go through several changes.

Receipt of deliverables has commenced against contracts with M/s Glavkosmos (Russian Space Agency) for space suit, crew seat and View port. Also receipt of deliverables under various work packages of CNES (French Space Agency) IA has commenced.

Yes, unfortunately, I didn't find any websites/channels that have good pictures of all the posters. This video has better visuals of Crew Module exhibit and posters visibility is a bit better (10:26 onward):
