ISRO's NavIC system has lost its ability to provide independent navigation services because only 3 of its 7 satellites are operational, falling short of the minimum 4 required. The government has admitted this in Parliament, though timing services and emergency messaging continue. This raises concerns about India's space-based navigation self-reliance, but the armed forces mitigate risk by using NavIC as part of a multi-constellation GNSS that includes GPS, Galileo, and Glonass.
