India Thursday successfully launched its third of its seven planned navigational satellites from its spaceport here. At 1.32 a.m. Thursday, the Polar Satellite Launch Vehicle (PSLV-C26) carrying the 1,425-kg Indian Regional Navigation Satellite System-1C (IRNSS-1C) lifted off. The 44.4 metres tall rocket, weighing around 320 tonnes is expected to spit out the satellite into the space around 20 minutes after the blast-off.br br The satellite, which was scheduled for launch Oct 10 but the launch put off by a week due to a glitch in the telemetry system, is part of the Indian Regional Navigation Satellite System (IRNSS) that will have a constellation of seven satellites to provide accurate positioning service for terrestrial, aerial and maritime navigation in 1,500 km area in the Indian peninsula.
