ISRO’s NVS-03 launch: What makes India’s NavIC different from GPS?

• ISRO launches NVS-03 on a GSLV-F18 rocket from Sriharikota at 11.51pm IST on Friday.
NavIC has only three working satellites, one short of the four needed to fix a position on its own.
The satellite carries an Indian-built rubidium atomic clock and adds an L1 signal that phones can use.
Its predecessor, NVS-02, failed to reach its working orbit in January 2025.
