Statement 2 is incorrect. NavIC provides coverage over India and a region extending up to 1500 km beyond its borders, not 5500 sq. km.
Statement 3 is incorrect. NavIC is a regional navigation system, providing coverage only over India and its vicinity. It is not designed to provide full global coverage. Global navigation systems like GPS, GLONASS, Galileo, and BeiDou have constellations of satellites orbiting the entire Earth.
