India is going to launch IRNSS-1D, the fourth Indian regional navigation satellite on March 9.
IRNSS (Indian Regional Navigation Satellite System) is going to be India’s own Global Positioning System.
Approximately Rs. 1,400-crore has been spent on it It can do what a U.S. military system can do and much better than that at a local level.
It will help the sat-nav team of ISRO to explore more of GPS in subcontinent.
Four satellites out of the constellation of seven are said to be the minimum the scientists need to check out signals and accuracy.
S.K. Shivakumar, Director of ISRO Satellite Centre in Bengaluru, told The Hindu that IRNSS-1D would finetune the details being provided by its earlier three siblings. The next three navigation satellites, he said, would take this to the targeted precision levels and make it easy to pinpoint required positions for many users. (http://www.thehindu.com/)
They will use the PSLV launcher to put IRNSS-1D in the orbit on February 28 at the Satish Dhawan Space Centre in Sriharikota. The first IRNSS-1A was launched in July 2013.
