New Delhi: The Indian Space Research Organisation (ISRO) is scheduled to launch its navigation satellite NVS-03 aboard the GSLV-F18 rocket on October 30 from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

The mission is aimed at strengthening India’s indigenous satellite navigation system, Navigation with Indian Constellation (NavIC

The satellite is the third in ISRO’s second-generation navigation series. Weighing around 2,250 kg, NVS-03 will carry an indigenous atomic clock alongside other atomic clocks.

It will also introduce the L1 navigation signal alongside the existing L5 and S signals, potentially improving compatibility with a wider range of civilian navigation devices.

NavIC is currently operating with only three satellites providing positioning, navigation, and timing services, while at least four are required for standalone positioning.

The system’s timing service remains functional, but it cannot independently determine a user’s position at present.

The launch follows setbacks involving earlier satellites, including NVS-02, which failed to complete its planned orbit-raising manoeuvres after its January 2025 launch.

ISRO has since implemented corrective measures recommended by an expert committee.

Even if NVS-03 launches successfully, NavIC’s full recovery will take time. The satellite must reach its intended orbit and become operational, while additional missions, including NVS-04 and NVS-05, are expected to strengthen the constellation.
