India's NaVIC Navigation System Down to Just 3 Satellites, Facing Critical Failure

• India's regional navigation system NaVIC, costing over Rs 3,200 crore, has been reduced to only three functional satellites—IRNSS-1B, IRNSS-1L, and NVS-01—below the minimum four required for accurate positioning, navigation, and timing services.
• The system, designed for seven satellites, suffered a major setback when the last atomic clock on IRNSS-1F stopped functioning on March 10, 2026.
• Failed launches of IRNSS-1H in 2017 and NVS-02 in 2025, combined with equipment failures, have left India's indigenous navigation system in crisis, posing security concerns for armed forces.
