Extract

Radio-navigation systems in which position is determined as the intercept of two range-difference hyperbolae require a minimum of three transmitters to provide a pair of base lines, which are inclined to each other at an angle as close to 90° as practicable. Calculation of position in such systems, e.g. Decca, Loran &c., is generally a relatively complex process as the hyperbolae intersect at a random and widely varying angle.
