Space technology and strategic autonomy: a key GS3 topic regarding independent navigation systems.

Why in news

ISRO is scheduled to launch the NVS-03 satellite to restore the NavIC system following repeated atomic clock failures and the failure to orbit NVS-02.

Background

The NVS-03 satellite launch is scheduled for October 30, 2026, at 23:51 IST from the Satish Dhawan Space Centre (SDSC-SHAR) in Sriharikota. The mission follows the development of NavIC which began after the 1999 Kargil War due to restricted U.S. GPS data access.
