Q.  Loran-C is a line of sight navigational system.

a. True
b. False


ANSWER: See Answer
 
Loran is a hyperbolic navigational system that came into usage right before the outbreak of world war II. The Loran-C uses ground waves at low frequencies, thereby securing an operating range of over 1000miles, independent of line of sight.
