ABSTRACT:
An apparatus (10) and method for allowing a moving user to automatically determine and store locations (11) over an extended period of time, to display the series of such locations (11), and to actively assist in returning to an earlier location. The apparatus (10) includes an antenna (16) for facilitating satellite lock, a fastening mechanism (18) for positioning the antenna (10) for best reception, and a satellite lock indicator (20) for communicating loss of satellite lock. The apparatus (10) also includes a timer (26) for measuring an interval during which the apparatus (10) is in a power-conserving sleep mode, and after which the user's current location is automatically determined. Active assistance in returning to an earlier location, either by traveling back along the path earlier traveled or by traveling along a more direct route, is accomplished by warning the user whenever the user's course deviates from the path or route.
