ISRO Successfully Launches Next-Gen Satellite, Key To India’s Satnav System

New Delhi:

Indian space agency ISRO today successfully launched a navigation satellite, NVS-01, on board an expendable rocket, GSLV-F12, from Sriharikota in Andhra Pradesh. Nearly 20 minutes after the flight, the rocket deployed the satellite in a geosynchronous transfer orbit (GTO) at an altitude of about 251 km, ISRO said. The navigation satellite has been successfully placed in orbit.

“We now have the ability to launch even bigger payloads,” ISRO said.

The Bengaluru-headquartered agency is launching the second-generation navigation satellite series, a significant launch which would ensure the continuity of NavIC (Navigation with Indian Constellation) services — an Indian regional satellite navigation system, similar to GPS, providing accurate and real-time navigation in India and a region extending to 1,500 km around the mainland.

NavIC signals are designed to provide user position accuracy of better than 20 metres and timing accuracy of better than 50 nanoseconds.

ISRO developed the Navigation with Indian Constellation (NavIC) system to meet the positioning, navigation and timing requirements of the country, particularly with regard to civil aviation and military requirements. NavIC was earlier known as the Indian Regional Navigation Satellite System.

Some of the applications of NavIC include terrestrial, aerial and maritime navigation, precision agriculture, location-based services in mobile devices and marine fisheries, among many others.

NavIC is designed with a constellation of seven satellites and a network of ground stations that operate 24×7. NavIC offers two services — Standard Position Service (SPS) for civilian users and Restricted Service for strategic users.

NavIC SPS signals are interoperable with the US global navigation satellite system signals, GPS, Glonass from Russia, Galileo (European Union) and BeiDou, China.

Monday’s mission is the sixth operational flight of the GSLV with an indigenous cryogenic stage. The mission life of NVS-01 is expected to be better than 12 years, ISRO said.
