Re: Indian Space Programme Discussion - Sept 2016
I could be mistaken on the 50 satellite payload, 37 is for certain, maybe a few of those haven't arrived as yet

While we wait for the LVM-3 launch... from the skyscrapercity forum.
Re: Indian Space Programme Discussion - Sept 2016
Look at this launch video. They have the loudspeakers from the launch center - no Doordarshan Bokwaas. Pure fun!
Ah, the clear skies that day, if only they had a telescoped stabilized camera... they could have captured so many things...
This video has everything a jingo wants, including the relevant stage parfaarmance naarmal, many times.

A brief but good video of the launch of GSAT-9, South Asia Satellite with GSLV-F09
I agree that full motion HD from the spacecraft would be wonderful and even more inspirational. At this stage I'm using up wishes for the successful launch of GSLV Mark-III, but perhaps we should aim higher and expect improvements on all fronts and not move forward with the intention to compromise all the time.

But the actual UAE footage on that video is just the part with the burka wearing babes. The rest is from the US customers video that you posted, but from a different angle. The US guys are clearly having trouble understanding what is going on. The DD guy is giving a ball by ball commentary with poems thrown in in good measure.
They are interpreting "Naarmal" as "Nominal" due to the Naarmal accents
One can hear them marvel at the flame to rocket ratio, and the super powerful solid boosters of the PSLV.

Video report on theNASA-ISRO Synthetic Aperture Radar (NISAR) Satellite from DNA from Zee TV. Video is in Hindi
NISAR is to be launched in 2021, and is said to be the most expensive SAR satellite.

I guess this news item answers my own previous question:KL Dubey wrote:BTW, does anyone know what is the commercial status of the Indian satellite-based positioning system (IRNSS/NAVIC) ? Are there now phones/navigation devices/apps that can use this system instead of GPS ? Or is this really just a "military use" thing ?
Get ready! India's own GPS set to hit the market early next year

http://timesofindia.indiatimes.com/home ... 876680.cms
India's very own desi Global Positioning System (GPS) is operational and is set to hit the market for public use in early 2018.
"The Indian Regional Navigation Satellite System (IRNSS) with an operational name of NavIC is currently being tested for its accuracy and is most likely to be available in the market for public use early next year," said Tapan Misra, the director of Ahmedabad-based Space Application Centre (SAC).
Misra said, "Academic institutions have been roped in to do ground verification and calibrate data of NavIC to find its accuracy. We have developed digital chips to miniaturise technology (for use in mobiles and handsets) and experiments are on them. The system is being tested all across the country."
Explaining the scientific reasons for NavIC's superiority over GPS, Misra said, "Our system has dual frequency (S and L bands). GPS is dependent only on L band. When low frequency signal travels through atmosphere, its velocity changes due to atmospheric disturbances. US banks on atmospheric model to assess frequency error and it has to update this model from time to time to assess the exact error. In India's case, we measure the difference in delay of dual frequency (S and L bands) and can assess the actual delay. Therefore NavIC is not dependent on any model to find the frequency error and is more accurate than GPS.

Re: Indian Space Programme Discussion - Sept 2016
I hope, really hope NaviC makes it.
I had really high hopes on Bhuvan but unless I have missed' it seems to have disappeared from public view. It was supposed to rival Google maps.

Re: Indian Space Programme Discussion - Sept 2016
Sir i think NaviC will make it only when indian govt. tells all mobile manufacturers if you want to sell mobile handsets in indian market after DD/MM/2018 you must include NaviC chips in it.
GOI may think about giving some preferential tax treatment too

Re: Indian Space Programme Discussion - Sept 2016
Indeed a very mild cheen type dictum must go out for all handset makers to support this in one year timeframe. The incremental cost in manufacture will be minimal given our massive market size and uniform referenve design needed. They can submit to govt labs for testing and carry on.
Re: Indian Space Programme Discussion - Sept 2016
Hope so, I can get away with this foreign lady's voice guidance that can't pronounce half Indian address names clearly.
Re: Indian Space Programme Discussion - Sept 2016
My Google maps voice guidance has an Indian voice over for local names. Pronounced correctly.
Re: Indian Space Programme Discussion - Sept 2016
Thanks will look it up, and hopefully need not have to take my eyes off the road to look at my phone.
Re: Indian Space Programme Discussion - Sept 2016
IIRC, you can select Indian voice for TTS at least on Andriod. I don't know about iPhones.

GSLV Mk III-D1/GSAT-19 Mission is scheduled to be launched on June 05, 2017 at 17:28 Hrs
GSLV-Mk III is capable launching 4 ton class of satellites to Geosynchronous Transfer orbit (GTO). It is a three-stage vehicle with two solid motor strap-ons (S200), a liquid propellant core stage (L110) and a cryogenic stage (C25).
GSLV-Mk III-D1 is the first developmental flight, carrying 3136 kg GSAT-19 satellite to a Geosynchronous Transfer Orbit (GTO). The vehicle is configured with a 5 m ogive payload fairing and slanted strap-on nose cone to provide aerodynamic robustness.
GSLV Mk III-D1/GSAT-19 Mission is scheduled to be launched on June 05, 2017 at 17:28 Hrs (IST) from the Second Launch Pad at SDSC SHAR, Sriharikota

Re: Indian Space Programme Discussion - Sept 2016
^ The striking change is the covering of the open truss of the cryogenic stage seen in this version. Probably related to the mild anomaly that was seen during the CARE LVM3 launch prior to booster separation.

Re: Indian Space Programme Discussion - Sept 2016
the truss and cryo stage are painted black. its still very much uncovered per the ISRO link above - unless they are using older pics.
Re: Indian Space Programme Discussion - Sept 2016
The solid strap-on tips are more aerodynamic, like in the GSLV-MK2s

Rains are fast approaching and the window is kind of iffy!
btw, wonder where are the huge doors with transporter rails for the new VAB?
Also payload shroud is more roundedGagan wrote:The solid strap-on tips are more aerodynamic, like in the GSLV-MK2s

So a rocket on the gantry will have to go out, then like a railway train, travel back, while changing track, and come onto the curved track that is visible.

But more like Ariane 4 in terms of payload capacity (4 tons to GTO), yes ?Singha wrote:Looks ariane5ish now.
Ariane 5 pushes 7-11 tons into GTO.
I think PSLV is equivalent to Ariane 1, whereas GSLV Mk I and II are similar to Ariane 2/3.
We catchin' up!
Re: Indian Space Programme Discussion - Sept 2016
For ISRO., it is easy to catch up by GSLV-MK III itself. It can upgrade the solid boosters by another 20-30% propellant weight to give a 250 tonne boosters., replace the core liquid stage with a five clustered C-25 stage (to give 1 MN core) and replace the upper stage with the GSLV Mk II's CUS (75 KN)., and increase the burn time of CUS. Again doing anything which is not incremental is an altogether new designed rocket
Of course there are many other variants possible., take out the core and replace it with equivalent clustered SCE to get a 10% more payload capacity. Or make it the gigantic GSLV-Mk IV with four boosters and with clustered SCE and bigger upper stage.
Point is, at this stage the engine development is reaching fruition (almost, for academic completeness SCE needs to be demonstrated)., it is now in the hands of the aerospace designers to come up with different vehicles that can use the engines in various stages.
The ogive nose cone sitting on the core rocket sometimes looks like the rocket propelled grenade! Basically the core can grow in heft (or diameter) and also grow in length (or tall) to be accommodated on existing launch platforms.
But just like PSLV was tinkered with from its initial launch of 800 kg SSO orbit to 1600 Kg SSO orbit (yes rounded figures)., so does GSLV Mk III can go from 4 tonne payload to 6-8 tonne payload.
However the next stage for ISRO is to design moon landings. For this., they will need to design in orbit docking and larger moon rockets.

Re: Indian Space Programme Discussion - Sept 2016
The current GSLV MK3s
Solid booster is the 2nd most powerful booster in the world
The cryo engine is the most powerful upper stage cryo engine in the world
The first stage will be better with the semi cryo being placed, payload will improve from 4 to become 6 tons to GTO
China and US use cryo in first stage. China's leaky old tech first stage cryo pumps out 550kN
The GSLVs upper stage cryo is 200kN
ISRO can easily design a bigger cryo or cluster them
Bottom line is that once ISRO demonstrates Semi Cryo, they will have mastered almost all the varieties of rocket engines out there.
They can then design any rocket for any payload, switch around engines and stages, cluster them as needed. The sky is the limit!
