ABSTRACT:
A global positioning satellite (GPS) receiver is used in an electronic lap counter which maintains a lap count and which increments the lap count upon "observing" via the GPS receiver that the user, having gone away from an initial "start" location (e.g., an end of a pool or the start line of a closed loop running track), has returned to that location. A user-supplied indication, such as the pressing of a push button, serves as an indication to the lap counter that the lap counter's then current location is to be used as the start location.
