ISRO schedules NVS-03 launch as NavIC faces satellite setbacks
India’s space agency plans to launch its third next-generation navigation satellite on October 30, after problems affected two earlier NavIC spacecraft.
The Indian Space Research Organisation (ISRO) plans to launch its NVS-03 navigation satellite from the Satish Dhawan Space Centre in Sriharikota, India, at 11:51 p.m. on October 30, The Hindu reported. The planned flight matters to India’s NavIC navigation system after problems affected two earlier satellites; whether NVS-03 can enter service will depend on the launch and subsequent operations.
The GSLV-F18 rocket is due to place NVS-03 into geosynchronous transfer orbit. PSU Connect also identified that destination and said the rocket would depart from the space centre’s Second Launch Pad. The Hindu identified the mission as the 20th flight of India’s Geosynchronous Satellite Launch Vehicle.
What NVS-03 is designed to add to NavIC
NVS-03 is the third satellite in a new generation intended to maintain services for the Indian Regional Navigation Satellite System, known as NavIC. The regional system provides positioning, navigation and timing services in India and an area extending about 1,500 kilometres beyond the Indian landmass, according to The Hindu.
ISRO said the new satellite carries an Indian-made atomic clock alongside procured atomic clocks, The Hindu reported. It is designed to add an L1 signal to the existing L5 and S signals. ISRO described coverage over India and a region extending 1,500 kilometres around its geopolitical boundary; PSU Connect also listed the clocks and signals among the satellite’s features.
Why earlier NavIC setbacks matter
The previous satellite in the series, NVS-02, launched on January 29, 2025. ISRO could not carry out its planned orbit-raising operations because of a valve malfunction, The Hindu reported. That setback gives the October mission added significance for the intended continuity of NavIC service.
Another NavIC spacecraft, IRNSS-1F, lost its procured onboard atomic clock on March 13, 2026, according to an ISRO statement reported by The Hindu. The agency said the satellite had completed its 10-year design life three days earlier and would continue providing one-way broadcast messaging for societal applications while in orbit.
The Hindu described the October mission as ISRO’s third launch of 2026, following PSLV-C62 on January 12 and GSLV-F17 on September 4. The scheduled launch is the next step for NVS-03; its planned contribution to NavIC depends on the satellite reaching its intended orbit and functioning there.
