ISRO flew NVS-03 with three pyro valves open to avoid past glitch

ISRO chairman V. Narayanan said the NVS-03 navigation satellite was operated with three pyro valves kept open to ensure mission reliability and sidestep earlier technical hurdles. Speaking after Saturday's launch from Sriharikota, he said the decision was cleared after rigorous vibration and shock tests by a national committee led by former ISRO chief Kiran Kumar. The previous NVS-02 mission in 2025 had failed.
