Through the polar sattelite launch vehicle, today It is learnt that the polar sattelite launch vehicle successfully placed ten sattelites in the orbit at the different stages.

I think this is world record.

what do you think that how much distance requires to keep in each ejecting sattelite in the orbit, for example the very first kept at 700KM hight, then for others !! is there a possibility of any interuption from the other sattelite which is kept more closer to the first. !!

Do you think that such sort of launching may reduce the "launching cost" per sattelite ??

You know that 6 of those sats were cube sats right? 1-3kg each. Tiny tiny tiny satellites.

14 cubesats were on a Dnepr rocket that failed to reach orbit in July 06.

You could, very very easily, launch dozens of cube sats on a single vehicle, even a tiny Falcon 1 vehicle would manage that.

It's still interesting to see more countries in space. We can't all be the first on the Moon. My congratulations to India.

It's too bad you didn't include a link to an article about this launch, though, suntrack2! Here's one.

Now India is bit ahead of China in space olympic. I have not yet heard whether china sent so many things at a time in space.!! I think such sort of mission will become more cost effective and more efficient in just one click more sattelites in a single carrier.

i havent heard that India has put a man in orbit......

China is still ahead, i dont know if in the commercial space olympic thought

Eh, it's nice to hear about India. Adults are always "China this" and "China that".

what, exactly, do these satellites do, and how long will they be up there?

The launch carried the following satellites:

CARTOSAT 2A: Indian Remote sensing satellite. Its supposed to be a dedicated satellite for Indian Armed Forces.

Life Time: 5 years

IMS1(Indian Mini Satellite): Earth observation satellite. It tests new miniaturized sub systems.

Life Time: 2 Years

The rest 8 were nano satellites built by students from various universities in Canada, Germany, Denmark, Netherlands and Japan. They are mostly to give the students a hands on at space tech.

CUTE 1.7 (Amateur radio satellite), CanX-2 (testing propulsion new system and attitude sensors and actuators), RUBIN-8( Test an automatic identification system (AIS) for ships), AAUSAT-II(Radiation sensor),NLS-5, SEEDS, COMPASS-1 and DELPHI-C3

Hi there
Doesn't launching 10 satellites means stacking one satellite on top of another and then poping them out at different altitude using pyrotechnics?

Can I say launching 10 satellites means:
1)you had enough space in the cone to fit them one on top of another
2)that pyros worked exactly at the time they should have
3)that on board computer knew where the rocket is and gave command to pyros at an required altitude
4)I think smaller (nano) are launched first and then the heavier ones like Cartosat, what say?
5)firing pyros means changing orbit, so this must be compensated by firing retros, right?
6)ok what else criticality is involved in this case which differs from launching only one satellite?

Ok thats it
Regards

You don't have to stack them vertically - in fact, they probably weren't.
It would be a lot easier to arrange them in a horizontal pattern perpendicular to the center axis of the rocket.

That's the system used for MIRV missiles ...
