BANGALORE: From the drawing board to the review room: Indian Space Research Organisation (Isro) and US' National Aeronautics and Space Administration (Nasa), who were in talks to co-develop a dual frequency synthetic aperture radar late last year. Now, the talks have converted into a project, with Nasa even having cleared Isro's instrument design.

The project, which Nasa terms Nasa-Isro Synthetic Aperture Radar (Nisar) will use advanced imaging that will provide an unprecedented, detailed view of the earth. "It is being designed to observe and take measurements of some of the planet's most complex processes, including ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides," Nasa's Jet Propulsion Laboratory has said.

TOI first reported about the two agencies being in talks for this in its November 11, 2013 edition under the title 'Isro, Nasa in talks to develop radar satellite'.

This was just after the initial mission concept review was done on October 15-16, 2013. On March 19, 2014, the project passed the crucial Key Decision Point-A (KDP-A) review, which, is an important stage in Nasa's Exploration Systems Mission Directorate's project life cycle module.

Following this, the agency will begin reviewing the critical design review, systems integration and operational readiness. Subsequent to this, on March 27, 2014, Isro's instrument design passed Nasa's review, which sources said, is another level of acceptability and a sign that the project's a 'go ahead'.

The satellite will not only be able to study natural hazard and ecosystem disturbances, but will also enhance remote sensing by improving the resolution of images.

"Isro also has on the drawing board development of remote sensing satellites with more autonomy, enabling them to identify areas of focus," a scientist said.

In what's being termed a first of its kind endeavour, Nisar will be able to operate in two frequencies, both in bands lower than KU-Band or AA-Band. While Isro will take care of the S-band radar, expected to have a 12-cm wavelength, Nasa will supply the 24-cm wavelength L-band radar.

This is great.

Go ISRO Go.

This is how work is done HAL & DRDO should learn something from ISRO

This is how work is done HAL & DRDO should learn something from ISRO

Exactly! HAL and DRDO should kick out the retired bureaucrats who have found a cushy post retirement parking slot in these organizations and who don't have a clue about what about WTF is going on. No wonder these directionless organizations are at the bottom of the food chain.

Satellite Capabilities
The NI-SAR satellite will will use the data collected in L' band, managed by Isro, and the 'S' band, managed by Nasa, to determine tectonic movements of the earth that lead to earthquakes, tidal wave surge, melting of glaciers and rise in sea level. The research will help in managing disaster to a large extent. [Reference]

In November 2013, ISRO Chairman K Radhakrishnan, referring to the proposed satellite, told Business Standard that the satellite is “about the study of pulse and knowing what is not normally visible under cloudy conditions…Through remote sensing, depending on the frequency, one can identify what’s there by depending on frequency characteristic change. For instance, the L-band studies vegetation, while the S-band and the X-band study other fields.

“We have done studies in the C-Band. In the project with JPL, we look at the L and S bands. The spacecraft will be made by us. A very large antenna would be required---one with a diameter of 12 m. This will be launched by 2019-20. In the second phase, we will carry out the project report preparation. Then, we will work on the satellite together.”

In an interview published in The Hindu on August 29, 2013, NASA Chief Bolden said, "There are a number of different satellites in different bandwidths that we're looking at; L-band is most prominent for us right now because it will potentially enable us to look at what we call the shifting of Earth, what causes earthquakes."

PTI in a report on July 29, 2013 quoted ISRO Chairman K Radhakrishnan as saying that the satellite "is interesting from scientific point of view, it's interesting from normal resource management point of view."


It will be launched by GSLV......
