Update:
1) Functioning of newly developed Head-end Mounted Safe Arm (HMSA) for solid motors in Crew Escape System was successfully demonstrated.
2) A parachute ejection test with Mortar was carried out at Terminal Ballistics Research Laboratory (TBRL), Chandigarh wherein sequential deployment of pilot parachute and drogue parachute was demonstrated.
3) As part of deceleration system qualification, main and drogue parachutes, in modified and improved pack cover configuration, was drop tested at ADRDE, Agra. Parachute Reefing Line Cutter [RLC] of main parachute was realised and development tests were also carried out.
4) Gas analysers for environment monitoring of crew cabin, cabin lighting system with intensity control and MEMS based barometric sensor have been developed.
5) Wind tunnel testing of Scale model of Crew escape system was completed in National Aerospace Laboratories, Bengaluru.
A unique state-of-the-art test facility – Environment Simulation Chamber (ESC) has been realised and commissioned at VSSC for stand-alone and integrated testing of Environmental Control & Life Support System (ECLSS) functional modules and Flight suit systems.
6) A Variable length-to-diameter [L/D] Lithium Hydroxide (LiOH) proto-canister has been realised as part of air re-vitalisation system development.
7) An integrated thermal performance test setup was realised for testing of crew cabin thermal and humidity control system and tests are in progress.

Crew module under vibration testing. SRE-1 had a very similar outer skin. What is missing of the crew module is its silica tiles thermal protection system that is also similar to SREs.

Space Suit Engineering Prototype
EPs help in technology development and demonstration. Final design will be based on the EPs test results
I love the red Sokol-ish suit - very 2001!
Hopefully, ISRO will eschew talking computers...

Look what I found!
Great! Just for the translation, I guess the first entry in the info box is Diameter, then Height, Volume and the last one is Mass? What does the set of volume entries in the middle circle mean? Is it the habitable volume available in the cabin for each spacecraft?

11. What about your plans for a manned mission?
While we are yet to take up a human spaceflight mission, we have progressed in technological areas such as crew module, crew-escape system, environment control and life-support system, space suit, re-entry and recovery techniques. Safety and reliability are important.

What will an Indian crew do in orbit? After test flights will they dock with ISS? And what happens when ISS is retired?
When the Chinese had their first piloted flight in 2003 they already had Tiangong planned as an interim space station. India has nothing like this planned.

If they are designing to IDSS standard, they will first have to demonstrate navigation and docking/undocking. After that, they could ask to visit either ISS or Tiangong-3. NASA does a lot interactions with ISRO. And if they demonstrate the necessary capabilities, both CNSA and the ISS partnership will probably want to have them on their side. Besides, at least ISS is done by bartering. If ISRO would pay to bring up (and down) their own crew plus somebody NASA, I don't see why they wouldn't accept them.
But realistically speaking, how far are we from them demonstrating the necessary capabilities. Even GSLV MkIII haven't flown and won't fly an orbital mission for a couple of years. We are talking 2020+ here. Who knows what will the international LEO station plans be by that time?

Something will go in space. it could be some kind of orbiting lab module with bio/metallurgy science. I read it somewhere, but I may be wrong.

Within a few weeks, the Indian Space Research Organisation (Isro) will team up with the Indian Air Force to conduct a simple experiment: it will drop a 3.7-tonne capsule from a height of 3.5 km and try to land it softly with parachutes. If successful, Isro will take this capsule in November-end to a height of 120 km on a rocket and eject it from there, to be recovered from the sea after a soft landing.
With this flight data we would be confident about our aero-thermal predictions," says S Unnikrishnan Nair, Project Director, Human Space Programme.
One can get a taste of the eventual flight from within a model capsule that is kept at the Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram. Two crew members lie looking up into the roof of the module, watching all the flight data as they move up.
The rocket with the passengers would lift off from Sriharikota, move in a nearstraight line towards Australia, where the crew module is pushed into orbit at a height of about 270 km by the cryogenic engine. The module completes seven days in orbit and then descend into the atmosphere to land softly in the sea.

Has the crew module reached SHAR yet? As per earlier reports they had a plan to attempt the launch within 2 weeks of PSLV-C26..
(EDIT: Okay, as per this
post the launch is tentatively for November end)

I'll x-post this to the GSLV-MkIII thread too, since this has stuff relevant to LVM3-X1 flight:
http://www.deccanherald.com/content/437480/isros-human-space-flight-endeavour.htmlThe first test trial, that of the crew module, will be undertaken in November last week or December first week on the GSLV MK-III.”
The crew module will be injected into orbit by the GSLV at a height of 110-120 km in space from where it will fall towards the earth and be recovered from sea. Isro will examine how the crew module and thermal shield around it handle the heat and temperatures during re-entry into the earth’s atmosphere.
The module’s behaviour during re-entry will determine the technologies to be developed for the manned space flight. The Indian Air Force will conduct trials of retrieving the crew module from sea after a soft-landing.
