The Indian Space Research Organisation (ISRO) is developing
a constellation of seven satellites to give a boost to the country's
security apparatus, a top scientist said here Sunday.
ISRO chief G. Madhavan Nair said the Indian Regional Navigational
Satellite System (IRNSS) was being developed "considering
security related issues".
Speaking at the Indian Institute of Technology-Delhi, Nair
said: "The proposed system would consist of a constellation
of seven satellites and a ground support segment. Three of
the satellites will be placed in the geostationary orbit and
four near the geostationary orbit.
"Such an arrangement would mean all seven satellites
would have continuous radio visibility with the Indian control
stations. The satellite payloads will consist of atomic clocks
and electronic equipment to generate the navigational signals,"
he said.
"The system is intended to provide an absolute position
accuracy of more than 20 meters throughout India and within
a region extending approximately 2,000 km around it,"
Nair explained.
The system will help in tracking infiltration activities
across the border and security personnel maintain better surveillance
over tough terrains, mountains or deep inside the sea.
The ISRO chief did not say when the system is expected to
be operational.
