No live coverage of Isro's spy sat launch
On Saturday, Isro officials told TOI the space agency has decided to do away with the traditional live telecast of the launch accompanied by a commentary by Doordarshan and other TV channels. The 48-hour countdown began at 6.45am on Saturday and the launch is slated for 6.45am on Monday at Sriharikota. Though TV crew members will be present at Sriharikota, they will, however, not be provided any facilities for covering the take off. "The TV is welcome to telecast the launch later in the day."

TOI's Srinivas Laxman quoting the deaf and dumb
Pakistan Defence, a website on Pakistan's security issues, has said the "newly-acquired satellite will immensely enhance India's capability to keep a tab on its unfriendly neighbourhood. Risat-2 is considered to be the first of its kind for India," it added.

PSLV places spy and education satellites into orbit
2009-04-20 07:50:29
Last Updated: 2009-04-20 08:39:03

PSLV_bBy Salil Jose in Sriharikota

The Polar Satellite Launch Vehicle (PSLV-C-12) placed two satellites into orbit on Monday morning.

It put into orbit the Radar Imaging Satellite (RISAT-2) and Anusat.

RISAT-2 is India's first all-weather spy satellite, while Anusat is an experimental mini communication satellite developed by Anna University in Chennai.

"Both the satellites have been delivered into the orbits," Indian Space Research Organisation (ISRO) Chairman Madhavan Nair announced minutes after the PSLV-C-12 blasted off from Satish Dhawan Space Centre in Sriharikota at 6:45 am.

RISAT-2 will enhance India`s capability in the management of disasters such as floods, cyclones and landslips. It weighs 300 kg and has an all-weather, 24-hour capability for imaging the earth. It can be used for defence purposes also since it has a synthetic aperture radar (SAR), built by the Israel Aerospace Industries.

RISAT-2 has a life span of three years.

The Anna University-developed Anusat will carry out drought and wasteland monitoring, urban planning and other studies. It weighs 40 kg and has a life span of one year. The Madras Institute of Technology, College of Engineering, Chennai and Pune University will be the users of the micro-education satellite.

Is it(RISAT-2?) in a Geo synchronous orbit? It needs to be parked on the LoC along Puki land border.
Atleast some relief to sniff out rats who slip in.
May be we need one just for BSF and IA dedicated on LoC along Puki border.

No. It's in LEO with 41 degree orbital inclination. Most spy satellites are in LEO.

Why is the Spy sat & its launch such a big news.
Shouldn't somethings be learnt of only 5 years after their existence ?

Now that the world knows what the Sat does & about its orbit, what stops people from pulling on us what we pulled on the americans sat. in pokhran...timing the activity to hide the subterfuge while the sat is hovering over? Or will this always be hovering over, making any activity visible anytime of the day ?

has the above already been discussed to death here?

Final countdown marked by anxious moments
The final countdown to the launch of RISAT2 satellite was marked by some anxious moments before ISRO scientists overcame a last minute glitch.

An 'umblical' connector from the top of PSLV-C12 got detached from the launch vehicle and fell on the others and about half a dozen connectors were "thrown out", ISRO chairman G. Madhavan Nair told reporters here.

"As usual, we had some drama yesterday on the countdown process. Last time (during launch of Chandrayaan-1 moon mission), it was the monsoon and rain which played havoc."

"This time, it (connector) simply fell on the connectors behind one after the other. About half a dozen connectors were thrown out. With that condition, we could not have gone on with the launch," he said.

But he said the ISRO team, being "real crisis managers," rose to the ocassion and made up six hours of countdown time working without a break, setting everything right and putting it all back.

"I don't think we can do better precision navigation than what happened yesterday {Very gratifying indeed}," he said after the successful launch of the satellite.

Describing RISAT2 as a "new year gift" to the country, he said it would be an asset and that only four nations had so far successfully launched such satellites.

Mr. Nair said every sub-system on board has performed to full satisfaction. The uniqueness of this mission was that for the first time, an indigenous computer, called advance mission computer, has been put on board, replacing the 30-year-old microcomputer.

"In the past, we have been depending heavily on the Canadian Radar satellite for our usage. Now we will become independent with our own indigenous capabilities in having the Radar imaging. It has got a very wide variety of application especially for the disaster management."

Mr. Nair said it is the first time that India is possessing a satellite working on microwave band, with the capacity to see through the clouds and can identify objects on the ground like water bodies, forest coverage and vegetation very precisely.

He declined to reveal the cost of the satellite, citing "commercial secrecy".

RISAT-2 not a spy satellite: ISRO chief

20 Apr 2009, 1300 hrs IST, IANS

SRIHARIKOTA: The radar imaging satellite (RISAT-2) launched by the Indian Space Research Organisation (ISRO) from Sriharikota on Monday is owned

and operated by ISRO, its chief said, dismissing reports labelling RISAT-2 a "spy satellite".

"This is an imaging satellite that can identify features on ground. There is nothing as a spy satellite. Though the satellite has a global coverage we will use it only for our use," ISRO chief G Madhavan Nair told reporters at a post-launch press conference.

He was reacting to media reports terming RISAT a spy satellite or defence surveillance satellite launched by ISRO's workhorse rocket Polar Satellite Launch Vehicle (PSLV) early morning on Monday.

However, informed sources said the satellite's synthetic aperture radar gives it day-night capability and the ability to look through clouds and fog, thus giving it defence applications.

The satellite launched on Monday is actually RISAT-2 that was fast-tracked in the wake of the 26/11 Mumbai attacks in place of the RISAT-1 that ISRO is developing.

The PSLV rocket also sent into orbit a micro-educational satellite Anusat built by Anna University with funding support from ISRO.

Though the launch went as planned, ISRO scientists spent tense hours Sunday as one of the umbilical chords holding the rocket to the launch pad fell off, damaging nearly six connectors.

"Six hours of countdown time were spent on setting things right," Nair said.

According to Nair, RISAT-2 has been positioned at a 41 degree inclination to enable it revisit a spot at frequent intervals.

Queried about the need for ISRO developing another such satellite, Ranganath R. Navalgund, director of the Space Applications Centre, said: "With two satellites the frequency of visits increases."

According to him, satellites orbiting in some frequencies cannot look at the earth very closely.

Not disclosing the price paid to the Israel Aerospace Industry, with which RISAT has been developed, Nair said: "Normally a remote sensing satellite weighing one tonne would cost around Rs 80 crore. This spacecraft is much smaller."

India now joins a select group of countries in the world like Canada, Israel, Japan and a few others in having such a precision satellite.

He said the launch of Anusat has prompted six other educational institutions like IIT-Kanpur and VIT-Vellore to approach ISRO for building such satellites.

Answering a question on the six month old Chandrayaan-1 moon mission, an official said the satellite was continuously sending data as it orbited the lunar surface.

On the status of the Chandrayaan-2 project, TK Alex, director of the ISRO Satellite Centre, said: "The project planning is in full swing. The two phased project will involve orbiting the moon and soft landing on the moon surface."

He said ISRO is working with the Russian space agency and is in the process of finalizing the test equipment that would go with the two rovers that would soft land on the moon.

"Engineering activity for the project is on and the launch will happen sometime in 2011 or early 2012," Alex said.

According to K Radhakrishnan, director of the Vikram Sarabhai Space Centre, ISRO's manned space mission involving an outlay of Rs 12,400 crore has got the green signal from the Planning Commission.

"We have to build a new launch pad, facilitation centre for the crew and mission control centre for manned rockets," he said, adding the rocket's cabin would also have to be certified for human worthiness.

"We will first send a couple of developmental flights (test rockets) before putting human beings inside a rocket," Radhakrishnan added.
