India Launches a Satellite to Keep Its Navigation System Running

The Indian Space Research Organisation launched the NVS-03 navigation satellite on Oct. 30, 2026, on the 20th flight of its Geosynchronous Satellite Launch Vehicle.

NVS-03 is the third satellite of India's next-generation navigation system, which ISRO says is meant to keep the service of the earlier IRNSS navigation satellites running. Its signals cover India's land mass and a region extending 1,500 km around the country's boundary.

ISRO's mission page for the flight says the rocket, designated GSLV-F18, lifted off from the Second Launch Pad at the Satish Dhawan Space Centre, Sriharikota, and placed the satellite into a geosynchronous transfer orbit. The agency calls the launch successful and the orbit the intended one.

A geosynchronous transfer orbit is a staging orbit, not a working one. It is elongated, and the satellite must raise itself out of it under its own power before it can take up station and start sending signals.

ISRO says the satellite carries an Indian-built atomic clock alongside purchased clocks, and that it adds an L1 signal to the L5 and S-band signals the system already broadcasts. The clock matters because a receiver works out its position from how long the signal took to arrive.

The vehicle's previous flight, GSLV-F17, launched the EOS-05 satellite in September 2026, per ISRO's list of recent missions.
