Any idea on launch timeline? Probably after GSLV Mk3 X1?
What is the typical turn-around time required for the First Launch Pad, involving all the cleaning, maintenance works and assembling of a new rocket? 2-3 months?
1C would be followed by 1D. Going by the recent/upcoming mission timelines and Oct/Nov cyclone period, this might get delayed to early Jan next year.
Before every satellite is sent up, the launch pad needs a 45-day pre-launch ‘campaign' and a 15-day post-launch refurbishing of burnt-out systems.
"The launch campaign for IRNSS 1D has come, which starts on January 16. Within two months, all components from other ISRO labs have to reach Sriharikota. The launch is likely after March 15," a senior ISRO official told PTI.
The other launches also relate to the IRNSS series with the IRNSS1E and IRNSS1-F satellites to be launched before the year end, he said.
The 59-hour countdown for the launch of IRNSS 1D satellite, which will help India kick-start functioning of indigenous navigation system on a par with the U.S.’ Global Positioning System (GPS), will commence at 7.35 am on March 7The launch is scheduled at the first launch pad of Satish Dhawan Space Centre at Sriharikota at 6.35 p.m. on March 9, a senior ISRO official told The Hindu.

Hmm....zero updates from ISRO at T-5 days? This is a first for them since a few years ago....
Now the satellite has to be dismounted from the Polar Satellite Launch Vehicle-27 rocket and moved back to its testing location where it will be rectified.
"We are planning to launch the satellite by the end of this month. The replacement transmitter is getting ready and will be brought from our centre in Bangalore," M.Y.S. Prasad, director, Satish Dhawan Space Centre (SDSC), told IANS
Do we know what the window is for the 15th? Around 13:00 UTC I'm guessing?
The Indian space agency is hoping to mate the country's fourth regional navigation satellite around March 19, after replacing a faulty transmitter on Monday, said a senior official."The new transmitter is expected to be fixed in the satellite and tested. Then the fully assembled satellite will be mated with the rocket," M.Y.S. Prasad, director of Satish Dhawan Space Centre (SDSC) told IANS over phone.The transmitter from Isro Satellite Centre, located in Bangalore and that is part of Indian Space Research Organisation (Isro), reached SDSC on Sunday.After mating the satellite with the rocket, a full system check would be carried out and then the rocket launch date would be fixed.

IRNSS-1D to fly on March 28The rescheduled navigation satellite IRNSS-1D will now be launched on March 28, ISRO Chairman A.S. Kirankumar said on Monday.
"The rocket - Polar Satellite Launch Vehicle-PSLV-XL - has been moved to the launch pad or the umbilical tower. The rocket will be fixed to the umbilical tower,"

I got this one to work:http://webcast.gov.in/live/ - but it's still in the daily news.If you see coverage on any other link, please post (and we'll take as many screenshots as possible).
Sad not to see the usual sight of Chairman Radhakrishnan (who's left).
Is this the first time we've been able to see strap-on jettison? I was rooting for the Tsiolkovsky cross, but that didn't seem to materialise. Commentator said visibility was so good that we might've been able to see S1 sep, but the cameraman slewed to a shot of smoke plume. :-/
With 4 IRNSS satellites, achieved minimum required configuration for IRNSS navigation service.
If the navigation service is a priority, why not launch 1E, 1F, and 1G as the next three PSLV payloads this year?Are there other considerations?Curious,Zubenelgenubi

Reasons cud be:1. As pointed out by Baldusi .. There IS one team ( we can see same faces in every PSLV launch video manning same consoles .. except payload specialists )2. Only 2 Launch assembly facilities hinder back to back launches in a very short period 3. Surely third party launches can't be sidelined for own 'secondary' missions .. Sky will not fall if IRNSS system is not up in immediate future. 4. IRNSS has a totally different orbit so they can neither be clubbed with Polar nor with 'PSLV launched GSO' payloads. They call for dedicated launch.

Read somewhere that the original plan was to spread the launches once every six months, and to retain two ground spares. Should be easier to maintain the constellation?
