ISRO Successfully Launches NVS-03 Navigation Satellite on GSLV-F18

The Indian Space Research Organisation has successfully launched the NVS-03 navigation satellite aboard GSLV-F18, with ISRO Chairman Dr. V. Narayanan saying the spacecraft was placed into the required orbit with very high precision.

The mission lifted off from the Satish Dhawan Space Centre, Sriharikota, and successfully placed NVS-03 into a Geosynchronous Transfer Orbit.

ISRO Chief Highlights Precise Orbital Injection

Speaking after the successful ISRO NVS-03 launch, Narayanan said the GSLV-F18 vehicle had injected the satellite into its targeted orbit with what he described as exceptional accuracy.

He said:

“The GSLV F18 vehicle has successfully and precisely injected the NVS03 navigation satellite into the required precise orbit.”

Narayanan cited the achieved perigee and apogee figures while highlighting the precision of the mission.

According to him, the perigee achieved was about 170.31 km, compared with a targeted 170.36 km.

He also said the mission achieved a highly accurate transfer orbit, describing the performance as among the best achieved by a launch vehicle.

20th Launch of GSLV

The mission marked the 20th flight of India’s Geosynchronous Satellite Launch Vehicle.

ISRO’s official launch records confirm that GSLV-F18/NVS-03 was the 20th GSLV mission.

Narayanan said that across its missions, the GSLV programme has carried a cumulative spacecraft mass of around 34 tonnes into orbit.

Shortest Turnaround Between GSLV Missions

The ISRO chief also highlighted the short interval between GSLV-F17 and GSLV-F18.

ISRO records show GSLV-F17/EOS-05 launched on September 4, 2026, followed by GSLV-F18/NVS-03 on October 30, making the gap 56 days.

Narayanan described this as the shortest turnaround achieved between two GSLV launches.

NVS-03 Strengthens NavIC Constellation

NVS-03 is part of India’s second-generation navigation satellite series designed to strengthen NavIC, the country’s indigenous regional navigation system.

ISRO says the satellite carries an indigenous atomic clock, along with procured atomic clocks, and supports L1 signals in addition to the existing L5 and S-band navigation signals.

The satellite is designed to serve India and an area extending approximately 1,500 km beyond the country’s geographical boundaries.

Four-Satellite Navigation Capability Restored

Narayanan said three navigation satellites were already operational and that NVS-03 would become the fourth satellite in the functioning constellation.

He said a minimum of four satellites is needed for reliable positioning, navigation and timing services, and that the latest launch would help restore that capability.

ISRO’s spacecraft status page lists IRNSS-1I and NVS-01 as operational for positioning, navigation and timing services, while NVS-02 is currently listed as not operational.

PM Modi Congratulates ISRO

Prime Minister Narendra Modi congratulated ISRO scientists and engineers after the successful mission.

He said NVS-03 would strengthen NavIC, support India’s pursuit of self-reliance in critical technologies and improve navigation services for citizens.

NavIC Gets Fresh Boost

The successful ISRO NVS-03 launch strengthens India’s independent navigation infrastructure at a time when satellite-based positioning, transport tracking, maritime navigation and strategic applications are becoming increasingly important.

The mission also adds momentum to ISRO’s GSLV programme after a rapid turnaround from its previous launch.
