What's new

India's spy satellite all set to keep a tab on Pakistan, China .

Why do you think distructively.. please think constructively.. why dont you guys send in a satelite.. which might help you in detecting any advance threat or troop movements from india... :D if we develop something.. you think about destroying it..!!!!!:lol: See that kinda thinking is not good for a country.. we have send in a satlite to protect our borders.. and i would suggest that you compete us in development and progress and not in distruction.. it will be good for the people of both countries..!!!

Any ways congragulations to my fellow country men.. for a succesful launch.. keeping fingers crossed for its successful operation...!!!

What is so destructive about having a ASAT capability. Both the US and China has it. Its a capability that one needs to have in order to achieve a higher end at war and to stop the enemy from gaining one.So I'll suggest you to get off from the moral high horse of yours and see it in prospective.

Well.. you dont have the resources to build a satelite.. and your are bloody thinking about developing a techonolgy to destroy a satelite.. Don't you sense or feel any irony in it..???????
 
Spy satellite RISAT takes off from Sriharikota :cheers:

SRIHARIKOTA, AP: Aiming to bolster India's defence surveillance capabilities, ISRO on Monday successfully launched its first all-weather spy
satellite that will help security agencies keep a watch on the movements on the borders, from its spaceport here. ( Watch )

The PSLV-C12, carrying 300-kg Radar Imaging Satellite (RISAT-2) and 40-kg micro educational satellite ANUSAT lifted off from ISRO's Satish Dhawan space Centre here at 6:45am and placed into 550 km orbit around earth.

The Polar Satellite Launch Vehicle, weighing 230 tonnes at the time of launch, soared into a clear sky from the spaceport here, about 90 km north of Chennai.

At the end of the 48-hour countdown, the 44-meter tall four-stage PSLV-C12 blasted off from the second launch pad with the ignition of the core first stage.

RISAT has all-weather capability to take images of the Earth and would also be beneficial in mapping and managing natural disasters, such as floods and landslides, besides amplifying defence surveillance capabilities of the nation. It would also help keep track of ships at seat that could pose a threat.

As per specifications, RISAT is different from previous remote sensing satellites as it uses Synthetic Aperture Radar (SAR), equipped with many antennas to receive signals that are processed into high-resolution pictures.

The SAR, developed by Israel Aerospace Industries, gives RISAT defence capabilities.

ANUSAT is the first satellite developed by an Indian university (Anna University), which would demonstrate the technologies related to message storing and forward operations.

University sources said scores of students and faculty from different streams had worked on this satellite for the last six years.

ANUSAT is a store-and-forward communication satellite that will help transfer confidential academic materials, including exam question papers, to prevent question paper leakages. It will also help monitor drought and wasteland, urban planning and other studies.

This is the 15th flight of ISRO's workhorse PSLV, which had launched 30 satellites (14 for India and 16 for foreign countries) into a variety of orbits since 1993.

RISAT and ANUSAT satellites placed in orbit

Press Trust of India / Sriharikota (ap) April 20, 2009, 11:58 IST

Aiming to bolster India's defence surveillance capabilities, ISRO today successfully launched its first all-weather spy satellite that will help security agencies keep a watch on the movements on the borders, from its spaceport here.

The PSLV-C12, carrying 300-kg Radar Imaging Satellite (RISAT-2) and 40-kg micro educational satellite ANUSAT lifted off from ISRO's Satish Dhawan space Centre here at 6:45 am and placed into 550 km orbit around earth.

The Polar Satellite Launch Vehicle, weighing 230 tonnes at the time of launch, soared into a clear sky from the spaceport here, about 90 km north of Chennai.

At the end of the 48-hour countdown, the 44-meter tall four-stage PSLV-C12 blasted off from the second launch pad with the ignition of the core first stage.

RISAT has all-weather capability to take images of the Earth and would also be beneficial in mapping and managing natural disasters, such as floods and landslides, besides amplifying defence surveillance capabilities of the nation. It would also help keep track of ships at seat that could pose a threat.

As per specifications, RISAT is different from previous remote sensing satellites as it uses Synthetic Aperture Radar (SAR), equipped with many antennas to receive signals that are processed into high-resolution pictures.

The 40 kg micro satellite ANUSAT, the co-passenger of RISAT 2, has been built by Anna University, to demonstrate the technologies related to message store and forward operations.

ANUSAT, the first built by an Indian University, is a 'store-and-forward' communication satellite that will help transfer confidential academic material and also monitor drought and wasteland, urban planning and other studies.

RISAT2 has a lifespan of three years and ANUSAT, one year.

Different from previous remote sensing satellites, RISAT2 uses Synthetic Aperture Radar (SAR), equipped with many antennas, to receive signals which are processed into high-resolution pictures.

The SAR, developed by Israel Aerospace Industries, equips RISAT with defence capabilities. The SAR payload can take images during day, night and in all weather conditions, including under cloud cover, a capability that Indian satellites do not have.

Nair said ISRO has "big goals" to achieve this year, referring to the line up of ISRO launches. "All this put together... It is going to be almost like the fireworks season at Sriharikota."

Today's is the 15th flight of PSLV, which has so far launched 30 satellites-- 14 for India and 16 for foreign countries -- since 1993.

PSLV had also launched the Chandrayaan-1 spacecraft on October 22 last year.
 
Its feels great to see our country galloping ahead of times. I feel confident that with the launch of this spy satellite we can address several of our security concers, especially regarding Pakistan.

However, it would be great if ISRO can come up with a military-only satellite.
 
I must congradulate my indian counterparts on this forum because of such a huge tecnological leap their country made after launching this spy sattalite .

This launch has certinly disturbed the geostrategik balance in the southasia .

In respect to this indian launch the Pakistan has also earned the right to carryout such sattelite Launch . So in other words our Indian Friends have provided us the License to carry out simillar tests. If we had done it before India we would have definately faced sanctions but now its a game on ...:tup::tup::enjoy:

Only if you can afford it. I don't think you do. Big brother IMF & your Tokyo donors will be watching.
 
Congratulation to all ISRO and all engineers and scientists involved !!
It’s a big step forward and I hope India will have more military satellite to have extensive coverage for not only her borders but all friends and foes.

For your kind info sir we made the nucklear bomb under the tough sanctions . We surely can make it now.
A strong Pakistan is in the favour of America, India and the whole world right.... So there is no ambiguity in carrying out such a launch .
That donors money is for the economy and war on terror. The funds for our strategik programes are fixed and predefined like in your country despite all the odds .

You never made it. You smuggled it. Designs were from Holland. Fissile material from Iran, technical expertise from China. And in the current sccenario when Pakistan last tested a missile in 1999 and under the more-than-ever scanner of UN/EU, its highly unlikely.

A post filled with ignorance, without an understanding of what I was suggesting.

I am not debating if you should or should not carry out a similar launch. I am pointing out the stumbling blocks.

Are you familiar with the conditions of IMF, under which loans are granted? First cut goes to defence allocations & spendings. Your economy ahs been udner the clutches of IMF since 1990s, still unable to come out. How would you look launching a spy satellite, when your government is roaming around with a beggar's bowl? That is the reason you have not tested a missile since long time, when India tested multiple versions of BrahMos, Prithvi etc.

I don't know what makes you say that your 'strategic allocations' are predefinied.

So what you mean is we cant even test fire missiles. I think we tested indiginiously Babur cruise missile not long ago .The current scenario is ideal for us to carry out such a launch . No one can stop us or would they .... Then i guess the reality will come before us and it would be easier for us to differentiate btw the friend and foe.

Developing a nuclear fuel is much easier than a developing a cyrogenic fuel engine. To develop a rocket engine that utilises liquid oxygen as a catalyst and liquid hydrogen as fuel is a huge quantum leap in technology. Imagine compressing Hydrogen to 20 degrees kelvin so that is becomes liquid and using that in an engine that uses that as a fuel !!

The easier thing is for Pak to co-develop a geostationary spy satellite and use one of the friendly allies (hint: :china:) to launch it into space!!

IMF lends the loan because those loans are needed to fight the poverty and the economic instability in the war affected areas . More ever some of the funds were also allocated to milletery operations .Defence budjet has certinly gone down but not because of IMF preloan conditions but because of American milletery AID to Pakistan which also includes a large portion of our Defence Budjet .
No conditions regardin strategik Programes are made and neither those will ever be accepted coz that is equivalent to selling our nukes for the sake of IMF loans.
Collin Powel once tried to impose sanctions on our missile programes but President Musharaff made him very clear that if you want our service in you war in Afghanistan than these sanctions are unacceptable After that no such hinderance from US has ever been seen regarding testfiring our Missiles .
 
Not all spy satellites are low-earth orbitting. Some are geo-stationary as well.

I agree Risat is a low-earth satellite, but however it takes about 55 minutes to rotate about the earth, so it doesnt create that much of a difference

In general, spy satellites are low earth satelites, and are not Geo Stationary. Since they pass each given location several times a day, they more or less capture everything that is required.

Low earth satellites relatively have lesser life, and need complex technology to maintain in order.
