<p>Scientists at the Indian Space Research Organisation (ISRO) on Sunday commenced the 27.5 hour countdown for the launch of a navigation satellite on board a GSLV rocket here on May 29.</p>.<p>The Bengaluru-headquartered space agency has drawn up plans to launch a second generation navigation satellite series which would ensure continuity of NavIC (Navigation with Indian Constellation) services.</p>.<p>The satellite would provide real-time positioning and timing services over India and a region approximately 1,500 km around the mainland.</p>.<p><strong>Also read | <a href="https://www.deccanherald.com/national/isro-chief-hails-role-of-sanskrit-in-india-becoming-knowledge-society-since-vedic-times-1221890.html" target="_blank">ISRO chief hails role of Sanskrit in India becoming knowledge society since Vedic times</a></strong></p>.<p>The countdown for the lift-off commenced at 7.12am on Sunday, ISRO sources said.</p>.<p>The 51.7 metre tall Geosynchronous Satellite Launch Vehicle, on its 15th flight, would carry the navigation satellite NVS-01 weighing 2,232 kg on Monday at 10.42 am from the second launch pad at the Satish Dhawan Space Centre (SHAR) here, about 130 km from Chennai.</p>.<p>Nearly 20 minutes after the flight, the rocket is scheduled to deploy the satellite in a geosynchronous transfer orbit (GTO) at an altitude of about 251 km, ISRO said.</p>.<p>The NVS-01 carries navigation payloads L1, L5 and S bands and in comparison to the previous one, the second-generation satellite series would also carry an indigeneously developed Rubidium atomic clock.</p>.<p>"The L1 navigation band is popular for providing position, navigation and timing, services for civilian users and for interoperability with other GNSS (global navigation satellite system) signals," ISRO said.</p>.<p>The Rubidium atomic clock, indigenously developed by Ahmedabad-based Space Applications Centre is an important technology which only a handful of countries possess, it said.</p>.<p>Some of the applications of the NavIC series include terrestrial, aerial and maritime navigation, precision agriculture, location-based services in mobile devices and marine fisheries, among many others.</p>.<p>Monday's mission is the sixth operational flight of the GSLV with indigenous cryogenic stage. The mission life of NVS-01 is expected to be better than 12 years, ISRO said.</p>
