The General Lighthouse Authorities (Beacons: Hyperbolic Systems) Order 1991
This Order provides for the references to a beacon in Part XI of the Merchant Shipping Act 1894 to include equipment and facilities in the United Kingdom which form part of a position fixing system known as the Loran C system so long as the United Kingdom is party to an international agreement concerning the establishment and operation of the system. The equipment and facilities would thus become subject to the superintendence and management of the General Lighthouse Authorities if the system were introduced into the United Kingdom.
