Abstract:
A method and apparatus for creating a dynamic GeoFence area by determining an instant reference point using a first set of pseudorange measurements received by a GeoFence device, defining the dynamic GeoFence area referenced to the instant reference point, determining a position fix using a second set of pseudorange measurements, and comparing the position fix to the dynamic GeoFence area. In one aspect, an alert message based on the comparison results is presented to a user.
