A FEASIBILITY STUDY OF A VLF RADIO COMPASS FOR ARCTIC NAVIGATION

Dimitri Petrov, Jacques Lamontagne and Jacques Laganiere

Abstract: Because of the erratic behaviour of magnetic compasses in the Arctic and long settling times of gyrocompasses in the vicinity of the north pole, the feasibility of a very low frequency (VLF) radiocompass in these regions has been studied. The operation of this instrument is explained by defining in spherical trigonometry the loci of points which subtend a constant angle with respect to two fixed references. Results of VLF radio direction finding in the Arctic are discussed. It is shown that vehicle heading can be determined with an accuracy better than 2”.
