23 July 2012 ... SPOT 6, the brand new Earth observation satellite built by Astrium, Europe’s leading space technology company, is now ready for launch. It will be transferred in the coming days from the Astrium Satellites facility in Toulouse (France) to the Satish Dhawan Space Center in India where it will be integrated with the PSLV launcher that will carry it into orbit ...

Since according to PSLV user's manual launcher/spacecraft integration requires about 30 days, a launch date of end August is more likely than August 16...

I would guess that this a countertrade deal, in which ISRO launches SPOT, and Ariane launches an ISRO satellite to GEO.

ISRO gets ready for historic 100th missionWe have today (so far) put 99 missions (62 satellites and 37 launch vehicles) from the days of Aryabhata (satellite) of 1975
So "a mission" can be a satellite or a launch vehicle...

Launch date confirmed September 9 at 0420UTC from FLP
3 satellites onboard: Spot-6, Proiteres and "India 50 kg Mini Redent Strapon Inertial Navigation System satellite"
http://www.thehansindia.info/News/Article.asp?category=1&subCategory=3&ContentId=80489
the
"Mini Redent Strapon Inertial Navigation System satellite" should read
"mini Redundant Strapdown Inertial Navigation System" (aka mRESINS).
It is a test of an improved, miniaturized version of the Redundant Strapdown Inertial Navigation System (RESINS) already used on PSLV and GSLV rockets. It features an additional avionics box fixed to the fourth stage and not a free-flying satellite. For guidance, this PSLV mission relies on the standard RESINS. If successful, mRESINS will take over for future flights.

Isro’s 100th mission: PSLV-C21 on September 9
The space agency has undertaken 99 missions, including 62 satellites and 37 launch vehicles, since the launch of the Aryabhatta in 1975.
They've miscounted.
4 SLV + 4 ASLV + 21 PSLV + 7 GSLV = 36 launches.
This is the 22nd PSLV, and the 37th launch overall, so assuming they do have 62 satellites (I don't have time to check), this is actually the 99th "mission", not the 100th.
That said, counting both launches and missions together does look as if they are trying to manufacture a milestone where none exists.

I've had another look at the "100th mission" claim, and assuming they meant 63 missions instead of 62 (balancing out my earlier point that the number of launches was wrong), that seems to match the number of satellites launched and intended to be operated by ISRO, including INSAT and joint missions with other organisations:
This includes the four commercially procured INSAT-1 spacecraft and INSAT-2DT which was purchased from Arabsat long after launch, counts Chandrayaan 1 and MIP separately, includes the avionics experiment on PSLV C8, and includes seven satellites which failed to orbit (the first Rohini, SROSS-A, SROSS-B, IRS-1E, INSAT-4C, GSAT-4 and GSAT-5P) and Rohini 2 and GSAT-1 which were placed into completely unusable orbits.
It also includes some satellites performing the same "mission"; such as INSAT-4CR, which was essentially a reflight of 4C after the failure.
Furthermore, the launch count makes no distinction between launches carrying satellites that have already been counted, and ones which are not. Every launch India has ever conducted has carried one or more ISRO-operated spacecraft. PSLV-C8 is the only launch to date which has not carried an ISRO satellite as its primary payload, and that flight carried the aforementioned AAM payload. Incidentally the only ISRO payload on the SPOT-6 launch is mRESINS, which is another avionics experiment.
EDIT: I forgot TecSAR - there has been one launch without an Indian payload
If the criteria are adjusted to avoid counting launch and operation separately for the same satellite, and eliminating complete failures, I would give the number of missions actually conducted by ISRO to be 54. ISRO would probably give that as 55, as they do not acknowledge that GSAT-1 failed.

To correct my earlier query, there weren't objects "on either side" of the core, there were four arranged at 90 deg. TVC?
That was a steep profile at times--what are the max gees on the payload?
So far so good--congrats ISRO/PSLV! I like your moniker ("In the Service of Human Kind").

What was the final inclination and altitude achieved for SPOT 6 ?
I see 659km in one screenshot...compared to 655 which was expected...quite good ?
I noticed that even after the launch, the ISRO Chairman took some time to confirm...so I was nervous whether anything went wrong....

ISRO's 100 Missions. Here is the list
http://www.isro.org/publications/pdf/100%20missions%20of%20ISRO.pdf
Eutelsat W2M and HYLAS? How, exactly, can they be regarded as ISRO missions?
Didn't the two satellites use ISRO's satellite bus?
http://space.skyrocket.de/doc_sdat/eutelsat-w2m.htm
http://space.skyrocket.de/doc_sdat/hylas.htm
They built them, but I wouldn't describe that as an "ISRO mission". Dawn used an OSC bus, but it is quite rightly regarded as a NASA mission, not an Orbital Sciences mission.
Well their definition of "missions" (counting launch flows and satellite construction/development/operation separately) is bogus anyway.....
Orbital would include Dawn in its list of 'Orbital missions'... the thing
is that ISRO is a spacecraft manufacturer/contractor as well as a spacecraft operator,
launch vehicle manufacturer, launch services provider, etc... and so it counts involvement in any of those roles
