LVM3 Moving out of VAB
Though called a 'giant' rocket, it kind of looks puny when seen in front of the VAB.
Maybe its because it is shorter than PSLV/GSLV.

Tracks from Vehicle Assembly Building (VAB) to Second Launch Pad (SLP).
Solid Stage Assembly Building (SSAB) in the background
Was just going to ask what was the building that I was seeing behind VAB. Thanks Chota!
Btw, what is that launch pedestral-like thing with rails which I see on the left bottom corner of the first image (kind of midway between SSAB and VAB)?
That is one of the PSLV/GSLV Mk. I/Mk. II MLPs on one of the MLP storage tracks in the VAB siding complex.

Interesting arrangement on that second stage (a dummy on this launch). The open section is not where the engine is located, it is the intertank section of the second stage. The engine is completely enclosed by the interstage below the open section.

Yes it's the same in the GSLV. Although I am not so sure about it's visual value (the LV could look better if it were completely covered).
Btw..OT..love your website! Great treasure trove of info. Keep up the good work!

Thanks! I kind of forgot that GSLV-III would have to use a different MLP design as against the one used by PSLV/GSLV-II

Ed, I believe you meant the C-25 cryo-stage when you mentioned the second stage, but (correct me if I am wrong) that seems to be the third stage as L-110 is air-lit around 10s before S-200s separate.
I guess C-12/15 stage of GSLV-II has a similar inter-tank section, but there the engine appears to be enclosed within the cryo-stage structure and not by a lower inter-stage.

Yes, it is a third stage, similar to Titan 3/4, although, since the first stage ignites about 20 seconds before the solids burn out and separate, it might be tempting to call it a 2.85 stage launch vehicle!

We can see the engine after separation of the stages

Whats the use of first stage SITVC when the stage has flex nozzles ? redundancy?

May be it's there for backup/testing purposes. Even GSLV Mk1
D1 flight had SITVC mounted on S125 solid motor even though L40 strapons had engine gimballing; and SITVC was removed in subsequent GSLV
Mk1/Mk2 flights.

The L110's air-lit isn't it? You'd need SITVC on the S-200s to steer until the core kicked in.
Also, it's interesting to note how the parachute harness on the SRE-1 was attached to the
bottom of the capsule, (i.e. the flat part of the cone) rather than the top. The illustrations in those
schematics of CARE, as well as the
picture of the
skeleton of the capsule seem to indicate that they're reversed this, and that the parachute will be attached to the top.
1 But the integration stage picture still shows the crew module being
handled/processed while "upside down" (i.e. heat shield on top) . Hell, it even seems to be interfaced to the
payload adapter while "upside-down".
Is it launching upside down? :-O lol
1 (Or does it? I'm guessing that the green-bag stowed on the top shelf is the packed canopy, and that the risers are the green straps. They seem to be hanging down - and I initially attributed this to them not having been attached as yet.)

S200 boosters have flex nozzles (
here,
here), so I guess they don't need additional SITVC?

Yes, crew module seems to be launched upside down. There were some discussions regarding that
here,
here and
here.

Drum roll !! 
Great! 
So 'LVM3' seems to be the name ISRO has settled to. Its written all over (S-200, L-110 and C-25)
actually LVM3 is the most appropriate name instead of GSLV MK III that media is reporting.
This being a suborbital flight as it does not carry active Cryogenic Upper stage ...and calling it GSLV will be paradoxical as it is neither intended nor capable of reaching Geo -synchronous orbit .
ISRO is particular about how and why it names and numbers its launch vehicles ...

right! i feel they will be keeping the SITVC for redundancy. just like the fins on the gslv mk2.

From second link you provided it says
The flex nozzle system with vectoring capability of + 8o
What does it mean? Is it +/- 8° ?

GSLV MK-III launch date to be fixed on Tuesday
The Mission Readiness Review (MRR) of the experimental flight of GSLV MK-III — the most powerful rocket built by Indian Space Research Organisation (ISRO) to date — will meet at Sriharikota on December 16 and take a call on the date of its launch.
ISRO sources said the launch was expected to take place two days later on December 18. “If everything was found satisfactory, the countdown for the launch will begin after the meeting of the MRR on December 16 and the launch will take place in the morning of December 18,” the sources said.
