The Indian Space Research Organisation (ISRO) successfully launched its Geosynchronous Satellite Launch Vehicle GSLV-F18 on the night of October 30, 2026, placing the next-generation navigation satellite NVS-03 into its intended orbit.
The mission marks a significant step in restoring and strengthening India’s indigenous satellite navigation system, NavIC (Navigation with Indian Constellation).
The 50-metre-tall GSLV-F18 lifted off precisely at 11:51 pm IST from the Second Launch Pad at the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh.
After a flight of about 18 minutes, during which all three stages including the complex cryogenic upper stage—performed as expected, the rocket injected the approximately 2,250 kg NVS-03 satellite into a Geosynchronous Transfer Orbit (GTO).
ISRO confirmed the mission’s success shortly after injection.
Mission Success!
GSLV-F18 has successfully placed NVS-03 in the intended orbit.
Congratulations!
ISRO Chairman Dr. V. Narayanan congratulated the teams, stating that the vehicle had “successfully and precisely injected the NVS-03 satellite weighing 2250 kg in the intended elliptical orbit.”
He noted that the systems performed as predicted and described the accuracy as among the best for any launch vehicle. The satellite was injected into an orbit of roughly 170 km perigee by about 37,000–38,000 km apogee.
NVS-03 is the third satellite in ISRO’s second-generation navigation series. It is designed to ensure continuity of services for the Indian Regional Navigation Satellite System (IRNSS/NavIC).
The satellite carries an indigenous atomic clock (alongside procured ones) and transmits signals in the L1, L5, and S bands.
Coverage extends over the Indian landmass and a region about 1,500 km beyond India’s geopolitical boundary. Once it reaches its final geosynchronous slot (targeted near 32.5° East) using its onboard propulsion, it will help restore the NavIC constellation to a minimum operational configuration of four satellites needed for basic positioning, navigation, and timing (PNT) services.
The launch comes after earlier challenges, including atomic clock failures on previous satellites and issues with NVS-02 reaching its operational orbit. With NVS-03, NavIC—India’s independent regional alternative to systems like GPS—gains renewed strength for civilian uses (vehicle, train, and maritime tracking, disaster management; precision agriculture) as well as strategic applications.
The mission also achieved one of the shortest turnaround times between successive GSLV flights (about 56 days).
Prime Minister Narendra Modi and other leaders congratulated the ISRO team, highlighting the contribution to self-reliance in critical space technologies.
NVS-03 has a planned mission life of around 12 years. ISRO will now oversee the satellite’s orbit-raising manoeuvres and commissioning in the coming days.
