Abstract : A ground unit capable of being carried on the back of a member of the armed forces is used in conjunction with a marker beacon. The ground unit detects and identifies the signals from the marker beacon and is also capable of indicating the direction in which the marker beacon is located. For identification purposes, a received signal at the ground unit from the beacon is checked with a known identification code signal inserted in the ground unit by the user. Upon detection of the signal the user can determine the direction to the marker beacon by scanning with a hand held antenna system. Visual and audio information is provided to the user.
