Rocket and Ballistic missile are almost same as on former we have Satellite in place of Nuclear warhead. I was thinking if we can place 104 objects in orbit then we should also use this tech as multiple independently targetable reentry vehicle(MIRV) with nukes in hostile situation and we have these large rockets which can easily travel more than 10,000 km. What your thought guys ? :sp

For PR all major space powers even Japanese are also giving live stream from their on-board rocket footage. So where is the problem if a better management team is in place for good PR ? And HD footage will also help our space scientists to detect performance anomaly if it was overlooked by telemetry data.

they know very well what to do and when to do after launching 104 satellites no one can doubt about it . If they wanted , they would change necessary things . But I guess currently for them main Aim is more imp than its broadcasting black bla bla :s

Here the light blue running North-South shows the intended orbit in which the satellites were to be released. Figure on left shows various Receiving and Control stations involved during this launch. They are : SHAR, Thiruvananthpuram ( TVM ), Port Blair, Mauritius and a Norwegian station at South Pole ( TROLL ). Every station has a limit of its visibility. It can,t communicate beyond this boundary due to the curvature of Earth's sphere which is shown by the circles around each station witha radius of about 2700 Kms. Notice that from launch to the point marked as C37, The rocket is visible to at least one station. But at that point the orbit goes beyond the visibility of MAU station and is not visible to any station till it reaches near South pole. If you had seen the live coverage you may remember that for about 6 minutes all the people in control room were just sitting anxiously but doing nothing. Actually the real satellite launch activity was going on at that time ( almost 80 satellites were released in that period ) but there was no communication from the vehicle that all satellites were released correctly because there was no communication between the vehicle and control room.
Only after the vehicle entered visibility of TROLL did they know that 'all is well' and we could see their gloomy faces turning into satisfactory grin.

The region where these satellites were released is shown in the figure on Right.
