Was there any mention of the launch schedule for 2016 in the Chairman's speech?
I listened to all the speeches, but no specific information was given. Mention was given to the three IRNSS launchers at a monthly rate and that they are working on PSLV C31, C32, C33 and 34.
And the goodies
Edit:
Great amateur footage.
Visibility was awesome and as far as Chennai it was startling people.
The imparted velocity is 7.10 km/s. Was there any issue? Same was observed in C30/Astrosat launch as well. What would be the impact on the payload if less velocity is imparted to it? I mean does the satellite, post-injection, need extra-LAM burn to achieve the required velocity?
Thx

Clear views all the way to fairing separation:
What would be the impact on the payload if less velocity is imparted to it?
the periapsis/apoapsis would be lower (depending on where the burn occurred)

These sats don't have a LAM so they are stuck. Orbital data now in, looks fine: 530 x 550 km orbits

No mention of the RLV-TD also........or did I miss it?

At the time of restart the fourth stage was in a lower altitude of 523.9 km while the satellites were ejected at 550 km altitude.
The engine operating for few seconds went up to an altitude of 524 km before the stage was cut off again.
(emphases mine)
They burned prograde? Huh? Why?
mmm I didn't pay attention to that but this Telugu source

Sriharikota (sullurupeta), December 17 (for life): Space Research Organisation agrarajyalaku the burgeoning labor ... without waste orbit, an experiment has had success in the first attempt. Nellurujilla Shore piesaelvi-C 29 rocket successfully launched Wednesday. Singapore has six satellites in orbit prescription. Another miracle in the experiment, the scientists were able to Shore. After the launch of the satellites in orbit debris from the rocket motors made the first attempt to bring back success. ISRO's ambitious attempts to implement the instructions of the United Nations to bring the waste undakudadanna orbit.
It appears it might've been retro to mitigate debris?
The payloads are in 530-550 km orbits, the stage is in a 400-570 km orbit, so the burn was mostly retro but not aligned exactly with the velocity vector.
First stage separation was tad too smokey. You can see some pieces fly off before(@25s Shaped charge going off?) and after(@43s) the big puff @ 30 sec mark.
Edit: Stabilized the relevant portion
