Abstract: A system, a signal bearing medium embodying a program of machine-readable instructions, and a method employing Global Positioning System (GPS) satellites to determine the current pace, the distance traveled and speed of a person, for example a runner, are disclosed. A GPS receiver for receiving signals from GPS satellites is attached to the person. A processor processes the signals received at a plurality of points from sub-sets of GPS satellites to determine the Earth Centered Earth Fixed (ECEF) fix in the x, y, and z planes relative to the center of the earth of each point. The processor detects when the signals are received from a different sub-set of satellites and corrects for the resulting fix error. The processor calculates the relative distance of the segment between the ECEF fixes of each pair of sequentially adjacent points, and adds together the distances of the segments to determine the distance of the path traveled by the person, which is defined by the points.
