A system that tracks the current and historical locations of a GPS locator device carried by a person provides widely available access to data referencing these locations, so that a parent can easily and frequently monitor the location of a child. Monitoring of a child's location may be conducted via a Web site, which provides graphical maps of location data, or via calling into a call center. The present invention also provides a means for a parent to trigger the automatic transmission of the device's location, via a Web site or call placed to a call center agent or a VRU. The present invention also provides a process of auto-notification of a device's movement that exceeds a pre-specified threshold. The present invention also includes a capability to function as a proximity alert device.
