The Indian Space Research Organisation (ISRO) on Monday (29th May 2023) successfully launched a second generation (2G) navigation satellite, using a GSLV rocket with a cryogenic upper stage to do the job. NVS-01 would augment the country's regional navigation system, providing accurate and real-time navigation.
* At the end of a 27.5 hour countdown, the 51.7 metre tall, 3-stage Geosynchronous Satellite Launch Vehicle lifted off at a prefixed time of 10.42 am from the second launch pad at this spaceport, situated about 130 km from Chennai. This was GSLV's 15th flight.
* The second generation navigation satellite series dubbed as a significant launch would ensure the continuity of NavIC (Navigation with Indian Constellation) services -- an Indian regional satellite navigation system, similar to the GPS, providing accurate and real-time navigation.
* Signals from NavIC are designed to provide user position accurate to better than 20 metres and timing accuracy better than 50 nanoseconds.
* ISRO Chairman S Somanath congratulated the entire team for the "excellent outcome" of the mission.
* "NVS-01 has been placed in precise orbit by GSLV. Congratulations to the entire ISRO team for making the mission happen," he said in his post-launch address from the Mission Control Center.
* The rocket, a little short of 20 minutes after it took off, deployed the 2,232 kg satellite into the intended Geosynchronous Transfer Orbit (GTO) at an altitude of about 251 km.
* NVS-01 carried navigation payloads L1, L5 and S bands and the second generation satellite also has an indigenously developed rubidium atomic clock..
