What is PNT?


Positioning, Navigation, and Timing (PNT) allows users to accurately determine their location, as well as guide them from one location to another, based on a defined time standard. PNT is provided by the following technologies:
·         Space Based (e.g., GPS, GLONASS),
·         Terrestrial (e.g., VOR, DME) and,
·         Autonomous (e.g., inertial navigation systems, clocks).
