Abstract :
This paper will discuss the interdependence between navigation and Precise Time and Time Interval (PTTI) systems. The modern role that navigation systems play in the field of timekeeping is shown through examples of how Omega, Loran-C, TRANSIT, and the Global Positioning System (GPS) are utilized by the PTTI community.
