Abstract
Sensors mounted in detachable modules are located at selected positions along a cable, such as one used in marine seismic exploration, adapted to be towed behind a vessel in a body of water. The sensors are selectively addressable, either individually or as a group, by coded signals sent through the cable. When addressed, the sensors provide readings of the earth's magnetic field vector. The readings are used to provide an indication of the position of the sensors and thus the cable relative to the towing vessel. Cable depth readings may also be made by the sensors.
