ISRO Chairman V Narayanan revealed that India’s NVS-03 navigation satellite was operated with three pyro valves already open to avoid technical problems experienced during the failed NVS-02 mission in 2025. The decision followed extensive vibration and shock testing by a committee headed by former ISRO chief Kiran Kumar. Launched aboard the GSLV-F18 rocket on October 30, NVS-03 successfully entered its designated orbit, restoring India's NavIC navigation system to its minimum operational configuration of four satellites. ISRO plans to launch NVS-04 within five months and NVS-05 within ten months to strengthen the network. (PC: PTI)
