• ISRO launched the GSLV-F18 rocket with NVS-03 from the Satish Dhawan Space Centre, Sriharikota, at 23:51 hrs IST on October 30, 2026.
• ISRO Chairman V Narayanan confirmed the satellite was placed in its correct elliptical orbit, calling it a step towards the "One Nation One Time" vision.
• NVS-03 is the third satellite of NavIC's second-generation series and the twelfth satellite in India's regional navigation constellation.
• NavIC is India's indigenous alternative to the US GPS, providing positioning services across India and up to 1,500 km beyond its borders.
• The system offers two services: the Standard Positioning Service for civilian users and the Restricted Service for authorised users.
• The new-generation satellite carries an additional L1 navigation signal, which improves compatibility with consumer devices.
• NVS-03 carries an indigenous atomic clock alongside imported clocks, reducing dependence on foreign suppliers for precise timing.
• Atomic-clock failures on several earlier navigation satellites had weakened the constellation, which was the reason for the replacement launch.
• The Kargil conflict of 1999 exposed India's lack of assured access to foreign GPS data and led to the creation of NavIC, earlier called IRNSS.
• GSLV Mk II is a three-stage, roughly 50-metre rocket with a cryogenic upper stage for geosynchronous transfer orbits, once nicknamed the "naughty boy" for past failures.
• Prime Minister Narendra Modi congratulated ISRO scientists, saying the satellite would add new capabilities to NavIC for all citizens.
• The upcoming NVS-04 and NVS-05 launches are expected to strengthen the constellation further.
