Frequently Asked Questions
Is NavIC more accurate than GPS in India?
Yes. NavIC uses dual-frequency L5 and S-band signals optimized for tropical ionospheric conditions, providing higher positional accuracy (< 5 meters) within India compared to standard single-frequency GPS.
Can my smartphone use both NavIC and GPS simultaneously?
Yes. Modern mobile processors (Snapdragon, MediaTek, Apple) support multi-constellation reception, combining NavIC, GPS, GLONASS, and Galileo signals.
