India’s effort to strengthen its independent satellite navigation system gained momentum on Friday night as the Indian Space Research Organisation (ISRO) launched the next-generation navigation satellite NVS-03 aboard the GSLV-F18 rocket.
The launch took place at 11:51 p.m. from the Second Launch Pad at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, marking another step in India’s effort to reduce dependence on foreign navigation systems and ensure continuity of its indigenous Navigation with Indian Constellation (NavIC) services.
“GSLV-F18 carrying NVS-03 lifts off from Satish Dhawan Space Centre, SHAR, Sriharikota,” ISRO said in a post 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 carried the 2,232 kg NVS-03 satellite, targeting deployment into a Geosynchronous Transfer Orbit (GTO).
Following deployment, the satellite is expected to perform a series of orbit-raising manoeuvres to reach its final geosynchronous orbital slot at 32.5 degrees East.
NVS-03 adds new signal to India’s navigation capabilities
NVS-03 is the third satellite in the second-generation NVS series, designed to augment the existing NavIC constellation and ensure the continuity of India’s regional navigation services.
The satellite carries an indigenous atomic clock alongside procured atomic clocks, an important component in determining precise positioning and timing information.
A key enhancement is the addition of the L1 navigation signal to the existing L5 and S signals. The inclusion of L1 is intended to expand NavIC’s capabilities and improve its usefulness for civilian navigation applications.
“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,” ISRO said.
The expanded signal capability is expected to strengthen NavIC’s role in providing positioning, navigation and timing services across India and the surrounding region.
NavIC is India’s independent regional satellite navigation system, developed to provide accurate Position, Velocity and Timing (PVT) services across the Indian landmass and an area extending approximately 1,500 km beyond it.
Unlike global navigation systems such as the US-operated GPS, NavIC is designed to provide India with an independent regional navigation capability.
Five second-generation satellites planned to strengthen NavIC
NavIC provides two categories of services, the Standard Positioning Service (SPS) and the Restricted Service (RS).
While SPS is intended for civilian users, RS is an encrypted service designed for authorised users.
The system has applications in transportation, maritime navigation, disaster management, precision timing and location-based services.
ISRO has envisaged five second-generation navigation satellites to augment the existing NavIC constellation. The new-generation satellites are designed to incorporate enhanced features and support the uninterrupted availability of navigation services.
The launch of NVS-03 comes as India seeks to strengthen the resilience of its satellite navigation infrastructure, which has applications ranging from everyday civilian navigation to strategic and security-related operations.
The satellite’s successful deployment and subsequent orbital manoeuvres will be crucial to its integration into the NavIC constellation.
