Abstract
It is the purpose of this paper to study how much the hyperbola formed by Decca Navigator System is disturbed by an isolated island in the open sea. The equiphase lines near a circular island are calculated with use of the electromagnetic compensation theorem by Monteath. As a result, the instanteneous phase velocity and the bearing error are obtained. On the other hand, the errors of LOPs for the red and the green patterns of Kita-Kyushu Decca Navigator Chain were measured around Iki Island by a ship. It is verified theoretically and experimentally that the hyperbolic pattern is bent towards the island in the both sides of the sea regions of the island situated near the baseline. Secondly, it is found that the change of the direction of the hyperbola corresponds to the bearing error.
