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.
Claims11
Apparatus for determining the location of a naval vessel, comprising:
- magnetic source means adapted to be connected to said vessel, for emitting an alternating magnetic field which has a predetermined orientation with respect to the vessel,;
- two magnetometers, adapted to be fixed to a sea bed below the water through which said vessel navigates, for detecting and measuring at least two components of the emitted alternating magnetic field;
- and
- location calculation means, coupled to said two magnetometers, for calculating the location of said vessel from the measured components of the emitted alternating magnetic field.
