Thread for the next GSLV MkII flight carrying INSAT 3DR- replacement for the INSAT 3D satellite (meteorological).

The next Geosynchronous Satellite Launch Vehicle launch will be the GSLV F09 mission and we plan to have it in July 2016
.
.
The GSLV F09 mission will have any one of the three satellites - GSAT-9, GSAT-7A or the INSAT 3DR - as payload, depending on the priority at the time

Why ISRO has selected INSAT-3DR over other satellites as already INSAT-3D in orbit with the same Imager & Sounder?

Does any one have idea on this?

Thx

INSAT-3D had some technical issues shortly after launch leading to limited operation. Hopefully INSAT-3DR will not run into the same issues.

FYI this should be the first launch where the indigenous cryo is flown in uprated configuration. Thrust will be increased from 73.55kn to 93.1kn and propellent loading will be increased from 12.8 tons to 15 tons.

Can you point me to source on that :)

The next mission, designated as GSLV-F05, is targeted for launch in July 2016 and will carry the 2200 kg INSAT-3DR meteorological satellite.  GSLV-F09 is planned in May 2017 to launch the GSAT-9 satellite.

The second meteorological payload should be referring to SCATSAT, which is planned to be launched in a PSLV flight later this year.

Isro Looking to Launch INSAT-3DR Weather Satellite on August 28

Quote
Preparations for the launch of weather satellite INSAT-3DR with the geosynchronous satellite launch vehicle (GSLV-MkII) next month are progressing at Sriharikota, officials said on Friday.
"The weather satellite INSAT-3DR will be put into orbit by a GSLV rocket August end. Preparations for the launch are going on," P. Kunhi Krishnan, Director of the Satish Dhawan Space Centre (SDSC), told IANS.

It is learnt that the launch is tentatively slated for August 28.

Indian GSLV will truly ‘arrive’ this month

Quote
Enters the all-Indian GSLV, finally, later this month. The GSLV-F05 flight coming up on August 28 or 29 will be its first regular, full-service or 'operational' one
Quote
GSLV-Mk2 however can put only satellites weighing up to 2,200 kg into geostationary space. At least four more of them are in the making now.

Another official said the plan is to do two GSLV launches a year from next year, apart from doubling the PSLV rate to ten or a dozen a year.

INSAT 3DR weighing only 2061 seems to be little lighter than it should be. Last year GSLV launched a satellite GSAT-6 weighing 2117kg. GSLV Project Manager Umamaheshwaran said last year after the launch that his team would gradually increase the payload up to maximum 2.5 ton by tweaking cryogenic engine in the subsequent launches.

Bur right now, it seems that GSLV II can't go beyond 2.2 ton capacity.

I think it will be a few more flights before we see GSLV fly in a uprated configration. Chances are they are trying to build up the realiablity of the base model to attract customers. PSLV did not get its first major upgrades till its 7th launch.

Possible upgrade path for GSLV:

Upgraded upper stage C-15 : 2.5 ton GTO
4 metre heatshield : More payload room
Uprated liquid fuel boosters + upgraded solid core: 3 - 3.5 ton GTO

Article noticed By Ohsin and trasnslated by me

A pyrocutter in the solar panel deployment mechanism was found to be faulty and needs to be replaced. Launch may be delayed by 3 days or 1 week.

Translation by /u/standardengineer
INSAT-3DR satellite has a technical issue.
GSLV launch likely to be delayed.
SHAR: As per sources GSLV launch due for Aug 29 is likely to be delayed. Launcher-satellite integration tests are going on. A pyrocutter is used to deploy solar panels in the satellites. The pyrocutter on INSAT-3DR did not meet the standards. They have decided to replace the pyrocutter. Spares are available. Scientists are studying whether to use a spare or to make a new one. GSLV launch will be delayed by three days if they use a spare pyrocutter, it could be delayed by a week if they decide to use a new pyrocutter.
Launch date was not agreed upon in the MRR.
MRR occured at Wednesday evening. They discussed the problems noticed in the solar panels. For this reason launch date was not confirmed. another review meet will happen on thursday.
Tl;DR; A pyrocutter used to deploy solar panels was found to be faulty and will need to be replaced.
