1. A detection device, said device comprising:

  • a receiver, the receiver determining intensity of a homing-signal transmitted from a vehicle and received at the device; and

    a controller-circuit in communication with the receiver, an inertial-measurement-unit configured to determine a distance the device is moved, and an electronic-compass configured to determine a heading in which the device is moving;

    the controller-circuit determining a first-range between a first-position of the device and the vehicle based on a first-intensity of the homing-signal;

    whereinthe first-intensity varies less than a variation-threshold;

    whereinthe controller-circuit determines whether the device has moved to a second-position based on a first-distance and a first-heading; and

    whereinthe controller-circuit determines a second-range between the second-position and the vehicle based on a second-intensity of the homing-signal.
