Bharat Rakshak

PSLV-HP should be able to push more, but I dont see any schedule for this satellite or this one is listed under GSAT series?

For PSLV, SPOT-6 & SARAL are planned for August / October respectively
For GSLV, there is a GSAT-6 in December, could be this one

could be on a Russian rocket too.

Not good to send Mil sats thru foreign launches

GD the launcher guy needs to know everything of the sat before integrating it.

"For GSLV, there is a GSAT-6 in December, could be this one"

If so, great news because for once, a launch has been advanced, not pushed back. The ISRO annual report mentions 3 GSATS 7, 10 and 14 being launched this year. One of them is probably an Ariane launch, one of the other two must be this 'secret' satellite. Or is the Naval satellite something else altogether, not part of that series. But from the launcher side, a GSLV mission in a month with an Indian made cryo would be fabulous!

Hope this chart is mostly provisional! Because a GSLV Mark 3 developmental launch in 2016-17 is depressingly late! A Frontline feature in 2003 speaks of a 2008 blast off!

And a semi cryo vehicle nowhere in sight....

<Added later> : nor is the RLV...

Manned space mission seems to be after 2020.

isn't x1 experimental vehicle (the last symbol in 2013 on the chart) resembling mk3 ?

It is Mk3. Looks like a sub-orbital shot, as stated below




Now that we are richer, we can afford to spread out risks like khan-saab with their programs since Mercury days

OT, but beautiful zooms of another heavy's first flight

mindboggling!!!! They managed to get even stage separation and beyond on camera. clear sky to help matters but that must be some hell of a zoom lens or telescope on the camera.

It would be awesome to see this happen for the mkIII

From the future plans chart - Scatsat-1. Seriously?

The bottleneck for the MK3 is the C25 upper stage - the experimental launch this year will test the launcher minus the C25. It will probably have a dummy upper stage and will outwardly look like the MK3 but will have a suborbital flight. Given the setbacks on the CUS for the GSLV, the delay is natural. All resources are focused on that project. Further, the C25 is not just a mere scaling up of the CUS.

The semi cryo project is not even at the project definition stage. It will take a few years for it to pick up steam.

In any case, ISRO tends to be ambitious (some would say unrealistic) with deadlines. Remember that the GSLV was supposed to fly in 1995 and with an indigenous CUS a couple of years after that.

GSAT-7 is Navy's MilSat. To be launched from Kourou

GSLV mk 2 will under go high altitude test rather the cryo acceleration block will and then if ok scheduled to be launched any time after october this year
strangely this is delaying C-25 engine test because same high altitude test facility will be used

C-25 is a new engine out and out and quite a bit of it is ready including most of ground support equipment .thrust chamber and engine testing was scheduled later this year but now guess nothing will happen till we have a successful mk2 launch . then things may accelerate I think

Any one have any info on what the C50 will be like?

I don't think C-50 is planned any time. this is the first time I'm hearing about C-50

Some mention of it at the below link. Not much though.

Why ? it is the one badly needed by all. Wind speeds over oceans is another critical parameter for other observations, not to mention shipping and marine needs. The idea of separating it on a separate sat unlike clubbing it with other payloads on Oceansat makes sense.

Actually there is something called C-60 as a follow on to the current C-25. Also a C-100 was proposed as well. Ofcourse this C-100 was meant for HLV with 100t to LEO

I am not sure what the designation given to the 600KN Cryo engine which is currently under development and was allocated 700 crore for 11th plan period.

Bade,

The comment related to the satellite's name, not the satellite itself.

usually setting up of wind energy parks requires a lot of study of ideal locations for consistent wind speeds, trying to determine the sites using ground based sensors for wind speed sampling might get expensive and time consuming, can the scatsat make an impact here? or is it only useful for macro level studies?

Oh I see Well you know the Amreekis have been calling the Scatterometer on board Oceansat-2, OSCAT sounds like the supplements one take OSCAL, since ISRO forgot to give it a proper name. The other payload is called OCM. So this time around they wanted a proper name, but still could not find one.

As an anecdote, I am told when Amerikis gave the name Quickscat to their now defunct scatterometer, the reason was that it was quick fire replacement at short notice for another failed mission/payload, hence the word "quick" a very unnatural name.

Over land no, since wind speed is measured as an indirect measurement from sea surface roughness as seen by the scatterometer.

danke Bade saab, now a days coastal wind farms are a rage,
far enough from the coast that they are out of sight of beach goers,

in the Indian context, with no real estate acqusition issues,
a very large coastline
with wind speed calibration from the scatsat
marine qualified turbine components and composite blades technology from DRDO
an Indian version of Suzlon energy should be in business

Suzlon Energy is an Indian company.

wonder why desi coastline is empty?

Same reason why Australia exports uranium but doesn't use any of it. Different priorities. Anyway... highly OT.

would agree to disagree on the priorities part, we are a energy deficit country; space applications should be ok on this thread.

What is the space application of this? Wouldn't a company investing in a wind farm want to get local measurements rather than rely on satellite based estimates?

I would think the satellite data would be useful for identifying locations with a strong potential for development but development would only commence after long-term local measurement. I'm happy to be corrected about this.

The discussions on wind power suggest India isn't doing anything in the field. On the contrary we've the 5th largest installed capacity and the 3rd highest annual capacity addition rate, behind PRC and USA, and ahead of all the Euro countries, whom we'll soon overtake in installed capacity at current rate of addition. Investment in windpower will be driven by cost of the energy; in an economy partial to the cheapest source of power, money will go into cheap hydrocarbon sources before wind.

Pratik & Suraj, between the capability of the current scatterometer and say a latter follow on that can detect the subtle surface wake of a shallow submerged sub, the case for local measurements for wind speeds can be made, at least in theory and a sat is ideal for repeated measurements over a time period

to become cost competitive, consider the per tower capacity, a higher capacity wind turbine for the same installation cost reduces per unit price and for such large turbines, sea locations without any obstructions are found to be ideal. KMGT is rated between 12-15MW, why not produce a wind turbine at that scale?

again, wind energy ROI is sensitive to the local measurements and the Indian coastine is vast, so sats may have a role to significantly reduce the lead time for wind parks

and at this point we are not even bringing in carbon tax

Offshore wind farms are unlikely to be viable in India in the near future due to their high cost compared to land based ones. Also, nobody manufactures/assembles offshore turbines in India; hence costs are likely to remain high.

almost 4 years since chandrayan flew, what has happened with all the data collected?

I got that one, send me a check

ISRO scientists praise Chinese space feat



We are too good onleee..

When is the next GSLV launch?

may be we should ask chinease help for cryogenic engine.

^^^Desi scientists are now play9ing pisko games by lauding cheeni space achievements so as to get the PRC to start complacently resting on its laurels rather than spur on further in competitive zeal. Better this reaction than dismissing it altogether (like the PRC did with our agni-V).
