Advantages of Interoperability to the Prudent Navigator

William J. Thrall

Abstract:	From the signal fire to the sextant, from the chronometer to radionavigation, man has always sought better, more precise ways and means to navigate. With the implementation of the Global Positioning System (GPS) leading to a Global Navigation Satellite System (GNSS), has the need for the other navigation systems been superseded or is interoperability of radionavigation systems a more prudent approach? This paper attempts to answer that question by first exploring the navigation needs of mankind (real and imagined) and describes the navigation systems that satisfy those needs, and then discusses the pros and cons of relying on only one system, GPS/GNSS, to meet those needs.
