PSLV-C6 / Indian Space Program

Sun May 08, 2005 5:57 am

On May 5, the Indian Space Research Organization (ISRO) conducted its 12th consecutive successful rocket launch, of the Polar Satellite Launch Vehicle (PSLV), which carried the 1.6 ton CartoSat-1 and the 40kg HAMSat, both locally built. Cartosat is a cartographic mapping satellite with a unique capability to generate 3D maps of the earth's surface. It joins the rest of the Indian Remote Sensing (IRS) satellites aloft, which constitutes the world's largest non-military remote sensing satellite cluster. HAMsat is a HAM radio communication satellite.

The PSLV-C6 mission was the third instance of multiple satellites being injected by a PSLV, after the C2 mission (IRS-P4, TUBSat from Tech Univ of Berlin and KITSat from Korea Inst of Technology) and the C3 missions (TES military surveillance sat, the German BIRD and Belgian PROBA satellites).

The PSLV is a 44.5m 295ton launcher with a capability of upto 4 tons to LEO and 1.3 tons to SSO/GTO (SSO payload restricted due to flight path complexity). All missions are conducted from the Satish Dhawan Space center, which has two launch pads, one capable of PSLV/GSLV and the other a universal VAB/launch pad.

The claimed resolution of CartoSat-1's cameras is 2.5m. Cartosat 2 (to be launched by another PSLV in October) has a claimed resolution of 1m. In any case TES has a claimed resolution of 1m too (and quite likely better in reality), and it has been in service for a few years now. It is known to be used by the military, since its images are not available in the public domain. Cartosat would be capable of generating data of military use, though.

I heard its one of the better resolution sattelites around,if not the best till date.

Quoting HAWK21M (Reply 1):

I just checked and it flys overhead at my house between 1130 and noon local. The press release says the orbit is sun synchronous so it should flyover everyones house between 1130 and noon local. That seems like ideal lighting conditions for photography - either spy or cartographic  Smile.

The press release says it launched at 10:15AM IST. I need a UTC time for my analysis and used 04:45AM UTC - Did I convert correctly?

BTW: The NORAD catalog numbers for the sats are: Cartosat-1 28649 and HAMSAT 28650.

SATL382G: If you're into tracking launches, there are three more planned in the coming months, two PSLV launches - probably in Oct 05 and Jan 06, and a GSLV launch in fall/winter 05. Launch rates are picking up since the second launch pad came online with the recent C6 launch, which means they can work on two launches in parallel. There are four planned launches in 2006 - three PSLV and one GSLV missions. The next PSLV launch will also have the SRE-1 space capsule recovery experiment related to the moon mission.

Thanks, I'll look for those.

My interest though is in naked eye visible sats. Photo sats in a noon polar orbit are a little difficult to see  Smile.

DOes that mean that the satellite will be photographing the moon at midday in your back yard?  butthead 

 Wink
Is my Pan Am ticket to the moon still good?

Nah, that means that it does a backflip and snaps the moon over Georgia at 1130PM....
