PSLV puts navigation satellite in orbit

India marched towards establishing its own navigation system on Friday when its Polar Satellite Launch Vehicle (PSLV-C24) put into precise orbit the country’s second navigation satellite, Indian Regional Navigation Satellite System (IRNSS-1B). The 1,432-kg IRNSS-1B will form part of a constellation of seven navigation satellites. It was the 25th success in a row for the PSLV, after it majestically lifted off from the first launch pad at Sriharikota at 5.14 p.m. After 19 minutes of flight, IRNSS-1B was put into a perfect orbit.
