Indian rocket Geosynchronous Satellite Launch Vehicle (GSLV) on Monday morning blasted off efficiently with the primary of the second technology navigation satellite tv for pc code named NVS-01 from the rocket port right here.

The three staged GSLV rocket standing 51.7 metre tall and weighing 420 ton rose up into the skies at 10.42 a.m. breaking freed from the earth’s gravitational pull.

The rocket carried India’s first of India’s second technology navigation satellites NVS-01 weighing 2, 232kg.

Interestingly, for the primary time, an indigenous rubidium atomic clock developed by Indian Space Research Organisation’s (ISRO) Space Applications Centre (SAC), Ahmedabad is being flown in NVS-01.

As the GSLV rocket ascended, its engine roar reverberated over the rocket port like a rolling thunder a lot to the fun of the individuals there.

Simply put, the NavIC an acronym for Navigation with Indian Constellation (previously with an extended winding identify Indian Regional Navigation Satellite System (IRNSS) is just like the GPS (Global Positioning System) of the US, Glonass of Russia and Galileo of Europe in addition to China’s Beidou.

A completely developed NavIC system consists of seven satellites in Geosynchronous/Inclined Geosynchronous orbits. It will present actual time positioning and timing providers over India and a area extending roughly 1, 500km across the Indian mainland.

About 19 minutes into the flight, the GSLV rocket will ship the satellite tv for pc right into a Geosynchronous Transfer Orbit (GTO) from the place it will likely be additional taken up by firing the onboard motors.

The satellite tv for pc with a mission lifetime of 12 years is powered by two photo voltaic arrays able to producing energy upto 2.4kW and a lithium-ion battery through the eclipse.

NVS sequence of satellites will maintain and increase the NavIC with enhanced options.

This sequence has payloads that function on L1, L5 and S bands thereby widening its providers.

The L1 navigation band is widespread for offering Position, Navigation and Timing (PNT) providers for civilian customers and for interoperability with different Global Navigation Satellite System (GNSS) indicators, ISRO mentioned.

“In addition to L1 band, we have a highly secured code for strategic signals in L5 and S bands, ” a senior ISRO official instructed IANS.

Currently there are eight first technology NavIC satellites in orbit. India had already launched 9 first technology NavIC satellites together with the 2 standby satellites.

The first standby satellite tv for pc was misplaced within the sky because the heatshield of the Polar Satellite Launch Vehicle (PSLV) didn’t open which necessitated the orbiting of the second standby.

The standby satellites have been used because the nation’s first navigation satellite tv for pc IRNSS-1A was not performing to the mark owing to the failure of its imported rubidium atomic clocks.

The atomic clocks are vital to provide correct positional information.

According to the ISRO official, out of the eight NavIC satellites in orbit 4 are purposeful for navigation providers and 4 others are messaging providers.

Be that as it could, ISRO had used imported atomic clocks on all of the 9 navigation satellites it had launched earlier.

It was mentioned the NavIC satellites have been performing effectively until the atomic clocks in IRNSS-1A failed.

Sources in ISRO had earlier instructed IANS among the atomic clocks in a few different satellites too weren’t functioning correctly. The clocks are used for exact time and site.

Each NavIC satellite tv for pc had three atomic clocks.

The outlay for the IRNSS/first technology NavIC methods was mentioned to be about Rs 1, 420 crore.

The eight NavIC satellites which are in orbit now are: -IRNSS-1A, IRNSS-1B, IRNSS-1C, IRNSS-1D, IRNSS-1E, IRNSS-1F, IRNSS-1G and IRNSS-1I.

The NVS-01 will develop into the ninth one if the mission is profitable.
