Navigation with Indian Constellation (NavIC) is India’s independent regional navigation satellite system designed to provide accurate Position, Velocity and Timing (PVT) service to users in India as well as to region extending about 1500 km beyond Indian land mass.

NavIC will provide two types of services, namely, Standard Positioning Service (SPS) and Restricted Service (RS). NavIC’s SPS provides a position accuracy of better than 20 m (2σ) and timing accuracy better than 40 ns (2σ) over the service area.
