ABSTRACT:
In order to guide a plurality of landing craft between, for example, a water-borne location and a shoreline, a first VOR-type transmitter is provided at the water-borne location, and a second VOR transmitter is located on shore. In a debarking operation, vessels beginning at substantially the same water-borne location and heading toward substantially the same shore location at the same time are directed to follow respectively different first radials from the first transmitter and second radials from the second transmitter. In this manner, both reliable guidance for a plurality of vessels and collision avoidance are achieved.
