NavIC and indigenous satellite technology: a key GS3 topic on space technology and strategic autonomy.
Why in news
ISRO successfully launched the 2250 kg NVS-03 satellite using the GSLV-F18 to restore NavIC services after previous satellite failures.
Background
The NVS-03 satellite weighs 2250 kg and was launched from the Satish Dhawan Space Centre using the GSLV-F18 vehicle. It carries an indigenous atomic clock and provides L1 signals alongside existing L5/S signals for a 12-year mission life.
