Gslv: Isro’s GSLV-F12 successfully places navigation satellite NVS-01 | India News – Times of India

CHENNAI: The Indian Space Research Organisation (Isro) on Monday successfully placed NVS-01, the first of the second-generation satellite series, into geosynchronous transfer orbit.
A Geosynchronous Satellite Launch Vehicle (GSLV) in its 15th flight placed the satellite, which will ensure the continuity of navigational (NavIC) services and also provide new service in L1 band.
On Monday at 10.42am, GSLV-F12 lifted off from the second launch pad at Satish Dhawan Space Centre, Sriharikota High Altitude Range.
Around 19 minutes after the lift off, the rocket successfully placed the 2232kg weighing satellite at 251km altitude.
ISRO chairman S Somnath said that the GSLV placed the satellite in the precise orbit. “After the issue in the cryogenic stage in the GSLV-F10 launch, corrections and modifications were made. NVS-01 is the first in the series of five satellites,” he said.
He also said with GSLV “there were issues in the past but I am sure that the full configuration we all dreamt to make it operational is on the way. The next GSLV launch will be with climate and weather observation satellite Insat-3DS and also in another launch it is bound to take India-Nasa synthetic aperture radar. “
The 51.7m tall GSLV, with a lift off mass of 420 tonnes, is on its 9th flight with indigenous cryogenic stage and 6th operational flight with the indigenous cryogenic stage.
Isro officials said NVS-01 satellite is built around the standard I-2K bus and compatible with GSLV. The satellite carries navigation payloads operating in L1, L5 and S bands. The satellite is powered by two solar arrays, capable of generating power up to 2.4kW and a lithium-ion battery supporting payload and bus load during eclipse. The mission life of NVS-01 is expected to be better than 12 years.
The Indian Regional Navigation Satellite System (IRNSS), operational name NavIC, provides accurate real-time positioning and timing services over India and a region extending approximately 1500km around the Indian mainland. The fully deployed NavIC constellation consists of seven satellites in Geosynchronous/inclined geosynchronous orbits.
Officials said compared to the first generation satellite series, the second-generation satellite series includes L1 navigation band and encompasses indigenously developed rubidium atomic clock. The rubidium atomic frequency standard (RAFS), the atomic clock which is the heart of the satellite, acts as a stable frequency reference for the navigation payload.
The L1 navigation band is popular for providing PNT (position, navigation and timing) services for civilian users and for interoperability with other Global Navigation Satellite System or GNSS signals.
The space-qualified rubidium atomic clock, indigenously developed by Space Applications Centre, Ahmedabad is an important technology which only a handful of countries possess, Isro officials said.
The key applications of Navic include terrestrial, aerial and maritime navigation, precision agriculture, geodetic surveying, emergency services, fleet management, location-based services in mobile devices, orbit determination for satellites, marine fisheries, timing services for financial institutions, power grids, and other government agencies, internet-of-things (IoT) based applications and strategic applications.
