Combining Loran and GPS: The Best of Both Worlds

Paul Braisted, Ralph Eschenbach, Anil Tiwari

Abstract:	Loran and GPS are both well known navigation systems, and both have advantages and disadvantages. By combining both, the navigator can get the advantages of both and analyze the disadvantages of each. When GPS becomes fully operational, it will replace virtually all other navigation systems. Until that time (late 1988), there will be substantial lapses of coverage. It is during this time that Loran provides the backup. This combination is the first system that can provide the transoceanic vessel with real time, accurate navigation information at both ports and periodic accurate navigation information en route. This paper will review the two systems and then show how the whole is greater than the sum of the parts. In particular, data will be presented to show how the combined product can yield better navigation information than either system by itself.
