‘RISAT to redefine disaster management’

Express News Service

BANGALORE: Radar Imaging Satellite (RISAT), to be launched on Monday by PSLV from Sriharikota, would not add any extra feature to the already available remote sensing system, when it comes to tracking human movements for border security, said ISRO Chairman G Madhavan Nair on Thursday. He was speaking to the media on the sidelines of the 54th Railway Week celebrations by the Bangalore Division of the South Western Railway.

“Interpretation of data from this satellite is not easy as the data obtained are reflected and scattered, which make the process of reconstruction of an image very difficult. We will have to learn the process. Moreover, our primary intention behind launching RISAT is to have a better satellite system for disaster management. RISAT would make India self-dependent in the field of using satellite for disaster management, as it is capable of working in all weather conditions.

RISAT, an Indian spacecraft, is capable of working in cloudy weather and at night, unlike the previous optical systems,”
Nair said.

Oceansat II by June

Oceansat II is expected to be launched by the end of June, Nair said. Oceansat I could take only coloured images but Oceansat II has a very powerful scatterometer that can collect data related to surface winds and wave heights.

Bhuvan in a month

Bhuvan, ISRO’s mapping tool using Indian satellites, is expected to start functioning in a month’s time, Nair said. He appealed to all the Indians to make use of Bhuvan to get data related to the Indian sub-continent.

Bhuvan would give data about India more accurately than any other mapping tool, he added.

Bhuvan is a satellite mapping tool and has been developed by the Space Applications Centre of ISRO. It works like Google Earth and Wikimapia.

Bhuvan is expected to give better and finer details than given by other webmaps, as it zooms far closer than the other tools. Google Earth zooms up to 200 metres distance and Wikimapia upto 50 metres, Bhuvan will show details up to 10 metres.

Bhuvan will use the data recorded by Indian satellites only and the data would be upgraded every year. Bhuvan will focus only on the Indian sub-continent.

Running trains to be satellite-linked

The Indian Railways system could soon be connected to the satellite system to handle disaster management in a quick and efficient way, said G Madhavan Nair, Chairman, Indian Space Research Organisation.

Speaking at the 54th Railway Week celebrated by the South Western Railway, Bangalore division, here on Thursday, Nair said: “In case of an accident at a remote place, the biggest challenge the authorities face is to make relief accessible to the victims. In some cases, the lack of immediate information about the accident also delays the relief-process. Connecting trains with a satellite terminal would enable us to transmit the information immediately. The information transmitted to a central station would hasten the process and also equipment can be dropped even before people arrive to help.” Nair said that talks were on between ISRO and the Railway authorities to start a pilot project in the next six months. The project would be a mobile unit, he added.

GPS equipped trains

The Railways can also be the best beneficiary of the GPS revolution.

Fitting trains with the GPS would help the control rooms track trains and provide immediate help if need be. India will have the GPS equipped trains by 2012, Nair said.

‘Must increase train speed’

The Indian Railways should work towards achieving the maximum speed of 300 kmph from the existing 150 kmph for trains, Nair said.

Indian Railways has proved its capability in providing efficient, economic and quality services and has seen great success in terms of revenue collection and punctuality.

Increasing the speed limit would help it become the best rail system in the world, he said. With space tourism picking up and with missions like Chandrayaan, vacations on the moon could become common in 20 to 25 years, he said.

PSLV-C-12 to put two satellites in orbit


CHENNAI: The Polar Satellite Launch Vehicle (PSLV-C-12) carrying two satellites will soar into the sky at 6.45 a.m. on Monday from the spaceport at Sriharikota, Andhra Pradesh.

It will put in orbit a radar imaging satellite called RISAT-2 and Anusat, a 38-kg. experimental mini communication satellite built by Anna University, Chennai.

S. Satish, spokesman for the Indian Space Research Organisation (ISRO), said the 48-hour countdown for the lift-off began at 6.45 a.m. on Saturday and filling the fourth stage of the vehicle with liquid propellants was under way. “Everything is proceeding smoothly,” he said.

Mr. Satish said RISAT-2 was a remote-sensing satellite and would enhance India’s capability in the management of disasters such as floods, cyclones and landslips. It weighed 300 kg. and had an all-weather, 24-hour capability for imaging the earth. The satellite would be put in orbit at an altitude of 550 km. and had a life-span of three years.

Anusat had provided the students of Anna University with a first-hand experience in building a satellite. It would help them in understanding the complexities of the hostile environment in which a satellite functioned, Mr. Satish said.

The mini-satellite carries a “store and forward payload.” Its secondary payloads are micro electro mechanical systems (MEMS), a MEMS gyroscope, a MEMS magnetometer and a satellite positioning system. The primary payload will enable its receiver to receive the information and its transmitter to read the information to the ground station when it is passing over an intended area.

Anusat will last a year. Its users will be the Madras Institute of Technology, Chennai; College of Engineering, Chennai; and Pune University.

RISAT-2 was procured from Israel and the heart of the satellite is the Synthetic Aperture Radar (SAR). This would work in X-band, used for military applications, informed sources said.

The PSLV-C12 would use new avionics. “The on-board computer has been changed. They are using advanced, high-level language,” the sources said.

The current launch vehicle is a core-alone version – without the six strap-on booster motors that form part of the standard PSLV. The core-alone vehicle, which looks sleek and elegant, weighs 230 tonnes while a normal PSLV weighs 295 tonnes. The rocket is 44 metres tall. It is a four-stage vehicle, with alternate stages powered by solid and liquid propellants.

I think ISRO has done right, the launch should be kept secret, it is out to out a military satellite. No need to broadcast this live on TV.

ISRO chairman G. Madhavan Nair said: "This is a fantastic New Year gift for the country. We are happy. Performance of the vehicle is precise. There is no deviation to the planned flight path. Both the spacecraft being delivered into the orbit."

He also said that 2009 is going to be the year of fireworks for ISRO. "We ll be launching resourcesat, oceansat and others. Indigenously developed cryogenic engine will be inducted this year."
