Scientists on the Indian Space Research Organisation (ISRO) on May 28 at 7.12 am commenced the 27.5 hour countdown for the launch of a navigation satellite on board a GSLV rocket in Sriharikota on May 29.
The Bengaluru-headquartered house company is all equipped to launch the second-generation navigation satellite sequence, a big launch which might make sure the continuity of NavIC (Navigation with Indian Constellation) companies — an Indian regional satellite navigation system, related to GPS, offering correct and real-time navigation in India and a area extending to 1,500 km across the mainland.
NavIC indicators are designed to present person place correct to higher than 20-metres and timing accuracy higher than 50 nanoseconds.
The 51.7 metre tall Geosynchronous Satellite Launch Vehicle, on its fifteenth flight, would carry the navigation satellite NVS-01 weighing 2,232 kg on Monday at 10.42 am from the second launch pad on the Satish Dhawan Space Centre (SHAR) right here, about 130 km from Chennai.
Nearly 20 minutes after the flight, the rocket is scheduled to deploy the satellite in a geosynchronous switch orbit (GTO) at an altitude of about 251 km, ISRO stated.
The NVS-01 carries navigation payloads L1, L5 and S bands and compared with the earlier one, the second-generation satellite would additionally carry an indigeneously developed rubidium atomic clock.
It is for the primary time that an indigeneously developed rubidium atomic clock could be utilized in May 29’s launch, the ISRO stated.
According to the house company, scientists earlier used imported rubidium atomic clocks to decide date and site. Now, the rubidium atomic clock developed by Ahmedabad-based Space Applications Centre might be on board. It is a vital expertise that solely a handful of international locations possess, it stated.
ISRO developed the Navigation with Indian Constellation (NavIC) system to meet the positioning, navigation and timing necessities of the nation, notably with regard to civil aviation and navy necessities. NavIC was earlier generally known as the Indian Regional Navigation Satellite System (IRNSS).
“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 stated.
Some of the functions of NavIC embrace terrestrial, aerial and maritime navigation, precision agriculture, location-based companies in cellular units and marine fisheries, amongst many others.
NavIC is designed with a constellation of seven satellites and a community of floor stations that function 24×7. NavIC gives two companies — Standard Position Service (SPS) for civilian customers and Restricted Service for strategic customers.
NavIC SPS indicators are interoperable with the US international navigation satellite system indicators, GPS, Glonass from Russia, Galileo (European Union) and BeiDou, China.
Monday’s mission is the sixth operational flight of the GSLV with indigenous cryogenic stage. The mission life of NVS-01 is anticipated to be higher than 12 years, ISRO stated.
