Abstract
Apparatus for determining the location of a naval vessel includes a magnetic source connected to the vessel for emitting a predetermined magnetic field. Two magnetic detection devices fixed to the seabed detect and measure at least two components of the emitted magnetic field. Location calculation means are coupled to the two magnetic detection devices for calculating the location of the vessel from the components measured by the two magnetic detection devices.
