Abstract
A magnetic sensor arrangement for monitoring movement of a vehicle on a path includes a three-axis accelerometer (1) and a processing circuit (2) for evaluating the vector product Hp of magnetic field vectors measured by the accelerometer when the vehicle is at two successive positions on the path. The vector product is utilized to evaluate a parameter related to vehicle trajectory. The arrangement may be used to generate a firing signal in an explosive mine or for monitoring a flow of vehicles along the path.
