ISRO plans Rs 1600 cr navigation satellite constellation

September 04, 2007 14:16 IST

India plans to build a constellation of seven geostationary satellites at a cost of Rs 1,600 crore to meet the navigational system requirements in cars, trains and aircraft.

"Design (of the satellites) is more or less complete. We are in the process of building the first proto model," Secretary in the Department of Space G Madhavan [Images] Nair said.

"First launch will take place around 2010. We should be able to complete all the satellites by 2012," Nair, also the Chairman of Indian Space Research Organisation, told reporters on the sidelines of an international space meet.

These seven geo-stationary satellites will cater to the navigational system requirements in cars, trains and aircraft, he said.

"It can provide accurate timing signals all over the place," and also find applications in surveying as well locating things in times of disaster.

"If you want to have a global coverage, we have to have a constellation of nearly 24 satellites which has to be going around all over the world... 20,000 km above the earth; whereas we have evolved a unique concept by which if you put in geostationary orbit, it will be continuously visible from our region. We need only a minimum number of satellites. Seven satellites will do this job," he said.

The Bangalore-headquartered ISRO is in the process of establishing the Indian Regional Navigation System based on these seven proposed satellites over India.

"For the constellation, we are going to spend around Rs 1,600 crore," Nair said.
