Rockets often use ‘container’ satellites for a bunch of sub-satellites. After the container is injected, it fires the sub-satellites into their respective orbits. Both the Dnepr and Antares rockets had container satellites. In the ISRO launch, however, each satellite will be ejected independently from the rocket.

That is correct. Fuel for the upper stages are filled in the last minute because the fuel fullup (especially for cryo stages) should be done in the safest way possible to avoid serious issues upto and including total launch failure. They need to be done in the last minute because they will boil off if they stay in the rocket (exposed to the elements) for too Long. This is different for military missiles which are usually placed in Silos and hence are in a much more controlled environment.

Altitude 511 Km now. ....................

 

[HariPrasad-1]

Altitude is decreasing now (Surprising)

Yeah and its cohesive to the inner lining too and cannot be stored longer i guess.

But pslv has no cryogenic stage. Ita gslv which has cryo stage.

But still you made valid statement.
