GPS as Aid to 2 Megahertz Hyperbolic Radionavigation Systems

Gregory R. Jenkins

Abstract:	Existing 2 MHZ hyperbolic radio-positioning systems have a common problem. When operations are interrupted an independent position fix, external to the system, is required for reestablishing coarse range information from the transmitting stations. More specifically, it is the whole number lane count which needs continuous identification during such operations. (The term "lane count" will be defined subsequently.) GPS can fulfill this special position fix requirement. The required type of GPS support depends upon the aided system, its mode of operation and its carrier frequencies. There are currently at least five such systems in use but only two, Raydist and Hyper-Fix, will be addressed in this paper.
