The Indian Space Research Organisation (ISRO) is preparing to launch its NVS-03 navigation satellite between October 15 and 20, a mission that could help restore NavIC’s standalone positioning capability. The satellite is expected to be launched aboard the GSLV-F18 rocket from the Satish Dhawan Space Centre in Sriharikota.
India’s Navigation with Indian Constellation (NavIC) currently has three operational satellites capable of providing positioning services. The government said in a July 2026 parliamentary reply that at least four operational satellites are required for NavIC to provide standalone positioning, while its timing service remains functional.
NVS-03 is part of a series of navigation satellites being developed to replace and augment the existing NavIC constellation. ISRO’s annual report identified NVS-03 as the third satellite in a planned series of five NVS spacecraft intended to strengthen the navigation system.
The shortage of operational satellites followed the end of the mission life of IRNSS-1F and the failure of NVS-02 to reach its intended operational orbit after its January 2025 launch. NVS-01, launched in May 2023, remains among the satellites providing positioning services.
A successful NVS-03 mission followed by orbital deployment and testing would bring the number of operational positioning satellites to the minimum required for standalone NavIC positioning. The system is designed to provide positioning, navigation and timing services for applications including transport, mapping and communications.
The upcoming mission is also part of a broader effort to rebuild India’s indigenous navigation constellation. The government has confirmed that NVS-04 and NVS-05 are in advanced stages of development and are expected to further strengthen the system.
