Abstract
A global navigation satellite system (GNSS) enabled mobile device comprising an Internet protocol (IP) interface may be operable to determine a reference position based on a registered public IP address associated with the GNSS enabled mobile device and range uncertainty for the registered public IP address. The GNSS enabled mobile device may identify the registered public IP address associated with the GNSS enabled mobile device and a packet travel time to reach the registered public IP address utilizing a network trace test. The GNSS enabled mobile device may be operable to determine the range uncertainty for the identified registered public IP address and validate the registered public IP address for a reference position based on the determined range uncertainty. The GNSS enabled mobile device may be operable to acquire a latitude/longitude associated with the validated registered public IP address for the reference position.
