Abstract :
Summary form only given. Loran-C, to be completed in 1990, is expected to provide coast-to-coast coverage over an area containing some 90% of Canada´s population, while the Global Positioning System is expected to provide worldwide navigation coverage by 1992. The fundamental signal propagation and measurement characteristics of the 100 kHz Loran-C and 1575.42 MHz GPS systems are described, together with their operating modes, accuracy, range, coverage, and reliability in the Canadian environment. Signal availability and interference in urban areas are discussed. The status of Loran-C and GPS user equipment is reviewed in terms of cost and suitability for land vehicle navigation.<>
