ISRO launches NVS-03 satellite aboard GSLV-F18 to boost NavIC

ISRO launched the NVS-03 navigation satellite aboard the GSLV-F18 rocket from Sriharikota at 11:51 pm on Friday. The 2,232 kg satellite is the third in the second-generation NVS series and will augment the indigenous NavIC system. NVS-03 carries an indigenous atomic clock and adds an L1 signal to the existing L5 and S signals.

ISRO launches next-gen satellite to boost India's indigenous GPS system

New Delhi, Oct 31

The Indian Space Research Organisation on Friday launched India's next-generation navigation satellite, NVS-03, aboard the Geosynchronous Satellite Launch Vehicle, GSLV-F18 rocket.

The launch took place at 11:51 pm at Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. "GSLV-F18 carrying NVS-03 lifts off from Satish Dhawan Space Centre, SHAR, Sriharikota," India's space agency ISRO said on X.

"Liftoff of GSLV-F18 carrying NVS-03 at 11:51 PM IST from Second Launch Pad, SHAR! ISRO's rescue mission for NavIC is now underway," it added.

The 50-metre-tall, three-stage GSLV-F18 rocket lifted off with the 2,232 kg NVS-03 satellite, aiming to deploy it into a Geosynchronous Transfer Orbit (GTO).

Once deployed, the satellite will perform orbit-raising manoeuvres to reach its final geosynchronous slot at 32.5 degrees East.

NVS-03 is the third satellite of the second-generation NVS series, intended to augment the Navigation with Indian Constellation (NavIC) system, an indigenous GPS of sorts, and support the continuity of navigation services.

NVS-03 is designed to augment the NavIC constellation and ensure continuity of navigation services. The satellite carries an indigenous atomic clock along with procured atomic clocks. It also incorporates the L1 navigation signal in addition to the existing L5 and S signals, enhancing the system's navigation capabilities.

"It also includes L1 signal in addition to existing L5/S signals with Coverage over India land mass and a region extending 1500 km around Indian geopolitical boundary," said ISRO.

NavIC is India's independent regional navigation satellite system, developed to provide accurate Position, Velocity and Timing (PVT) services to users across India and the region extending approximately 1,500 km beyond the Indian landmass.

According to ISRO, NavIC provides two types of services, the Standard Positioning Service (SPS) and the Restricted Service (RS). While SPS is intended for civilian users, RS is an encrypted service for authorised users.

ISRO has envisaged five second-generation navigation satellites to augment the existing NavIC constellation with enhanced features and ensure continuity of services.

What the report makes clear: ISRO has launched NVS-03, the third satellite in its second-generation series, to strengthen the indigenous NavIC navigation system.

Still open: The report does not yet say when NVS-03 will reach its final orbital slot or when the full five-satellite constellation will be complete.

Another way to look at it: An indigenous navigation system reduces dependence on foreign networks, though its full benefit depends on devices being built to use NavIC signals.

How important do you think an indigenous navigation system is for India?
