According to the Hindu.com article, there is also a secondary payload of 180 kg: India's Advanced Avionics Module (AAM)
I guess, this one remains attached to the fourth stage as it only tests new avionics for future PSLV flights.

I think that there is still mutch work to be done with Vega before the first commercial launch.

Their latest test failure could end up setting them back and additional 6 months to a year from their original planned timeline.

PSLV usually has several strap-on motors and two tanks that hold the injection fluid for the first stage thrust vector control system.  This PSLV doesn't have any strap-on solids, but it appears to have four of the injection fluid tanks.  Either the launch vehicle needs more TVC fluid in the absence of strap-on booster augmentation, or the extra "tanks" are part of an auxiliary roll control system.

reportedly two of the pods are roll-conrol engines, not fluid injection tanks.

Vega will also be twice the price of PSLV-CA (i.e. PSLV-C w/o strap-ons).

1. Vega's first launch is NET End of 2008.
2. Vega has a payload capacity to a 700km circular oobit of 1.5 tons. AGILE has a mass of 360 kg. A launch on Vega would have been a bit of an overkil unless AGILE would be the secondary payload on Vega... however, CNES launched COROT (600kg) on a Soyuz-2...

Congratulations to this successful launch! Nice to see the PSLV is becoming a reliable launcher that even lofts paying customers' satellites... let's hope the GSLV overcomes its difficulties and does so too.

PSLV Successfully Launches Italian Satellite
April 23, 2007  
 
 In its eleventh flight, conducted from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, this afternoon (April 23, 2007), ISRO’s Polar Satellite Launch Vehicle, PSLV-C8, successfully launched the 352 kg Italian astronomical satellite, AGILE, into a 550 km circular orbit, inclined at an angle of 2.5 deg to the equator.

PSLV-C8 mission was unique in many respects. In this mission, PSLV was flown, for the first time, without the six strap-on motors of the first stage. Also, for the first time, PSLV launched a satellite into an equatorial circular orbit of 550 km. PSLV-C8 was the first major commercial launch the contract for which was won against stiff international competition.

Along with the Italian satellite, AGILE, an Advanced Avionics Module (AAM), weighing 185 kg, to test advanced launch vehicle avionics systems like mission computers, navigation and telemetry systems, was also flown on PSLV-C8. All the operational flights of PSLV so far have been successful and thus PSLV has emerged as the workhorse launch vehicle of ISRO.

After the final count down, PSLV-C8 lifted off from the Second Launch Pad (SLP) at SDSC SHAR at 3:30 pm with the ignition of the core first stage. The important flight events included the separation of the first stage, ignition of the second stage, separation of the payload fairing at about 116 km altitude after the vehicle had cleared the dense atmosphere, second stage separation, third stage ignition and third stage separation, fourth stage ignition and fourth stage cut-off. AGILE was placed in orbit 1370.7 sec after lift off.  

With a much lighter payload and the low inclination of the orbit in which AGILE was to be placed, PSLV-C8 was configured, for the first time, without the six solid propellant strap-on motors of the first stage. Also, the propellant in the fourth stage had been reduced by about 400 kg compared to the previous PSLV flight. The core-alone PSLV-C8 had a lift-off mass of 230 tonne.

PSLV has emerged as the workhorse launch vehicle of ISRO with ten consecutively successful flights so far. Since its first successful launch in 1994, PSLV has launched eight Indian remote sensing satellites, an amateur radio satellite, HAMSAT, a recoverable space capsule, SRE-1, and six small satellites for foreign customers into 550-800 km high polar Sun Synchronous Orbits (SSO). Besides, it has launched India’s exclusive meteorological satellite, Kalpana-1, into Geosynchronous Transfer Orbit (GTO). PSLV will also be used to launch India’s first spacecraft mission to moon, Chandrayaan-1, during 2008.

In its standard configuration, the 44 m tall PSLV has a lift-off mass of 295 tonne. It is a four-stage launch vehicle with the first and the third stages as well as the six strap-ons surrounding the first stage using HTPB based solid propellant. PSLV’s first stage is one of the largest solid propellant boosters in the world. Its second and fourth stages use liquid propellants. PSLV’s bulbous payload fairing has a diameter of 3.2 metre. The vehicle has S-band telemetry and C-band transponder systems for monitoring its health and flight status respectively. It also has sophisticated auxiliary systems like stage and payload fairing separation systems.

AGILE

AGILE is an X-ray and Gamma ray astronomical satellite of the Italian Space Agency (ASI), Rome. The design, development and fabrication activities of the satellite were led by Carlo Gavazzi Space, Milan, Italy. The launch was arranged by Cosmos International through Antrix Corporation. The satellite carries scientific instruments capable of studying distant celestial objects in X-ray and Gamma ray regions of the electromagnetic spectrum.

Interesting articleAt $29,000 a key that makes a little under $10mln for the flight, but this is mainly due to the specific orbit. 3 more launches scheduled for this year, 1 x GSLV + 2 x PSLV

This mission placed the payload in an orbit at 2.9 degrees inclination. As far as I know, no other PSLV has put a LEO payload in such a low inclination orbit. Because of the unique orbit, this mission would have entailed unique drop zones, a unique flight path, and some sort of unusual yaw control. But, nothing was written about that aspect of the mission, so it’s all a minor mystery.

Yes, AGILE's 2 degree inclination was the least inclination orbit provided by PSLV. Other notable ones are

Astrosat -  6 deg incl
TeLeos-1 + other satellite - 15 deg incl
TecSar and Risat-2 - 40 deg incl
