Follow renewal and service availability

NVS-01 launched on May 29, 2023 as the first second-generation NavIC satellite and carried an Indian-developed atomic clock. The NVS design adds a civilian L1 signal alongside L5 and S-band navigation signals. A receiver must support the relevant signal; announcing a new band does not make every older device compatible.

ISRO’s January 24, 2025 account describes NVS-02 ground tests and planned service role. The thermal-vacuum photograph shows test preparation. Such testing provides evidence within its conditions, but it cannot by itself establish that the later mission reaches its operating orbit or enters service.

NVS-02 reached its elliptical transfer orbit on January 29, 2025, but the subsequent orbit-raising operation could not be carried out. ISRO’s February 25, 2026 account separates successful launch injection from the spacecraft problem. Those outcomes can coexist because the launcher and the spacecraft perform different parts of the delivery sequence.

The investigation found that the drive signal did not reach the oxidizer-line pyro valve used for the orbit-raising engine. The committee identified connector-contact disengagement in the main and redundant paths as the most likely cause. That wording reports an investigation conclusion, not a photograph of the failed contact; the ground-test image does not expose the internal failure.

A Department of Space parliamentary answer dated July 29, 2026 reported three satellites supplying position, navigation and timing signals: IRNSS-1B, IRNSS-1I and NVS-01. It stated that the constellation could not then provide standalone positioning, while timing remained functional. This is a dated operational account, not a permanent status label or a claim that every NavIC-related function stopped.

The same account described use within multi-constellation receivers and preparations for additional satellites. Signals from other systems can contribute to a combined solution when the equipment supports them. A combined position result is not proof of an independent NavIC-only position, and a satellite described as ready for launch is not yet evidence of restored service. Current use requires current operator information.
