In a method for requesting network-derived position data from a mobile geographic position aware receiver, a mobile geographic position aware receiver having a first IP address is communicatively coupled with a first port on a router. A wireless transceiver is communicatively coupled with a second port on the router. a wireless communication device is communicatively coupled with a third port on the router. A processor is communicatively coupled with the router; the processor for executing a communications access command sequence. The command sequence comprises: testing for a wireless network connectivity; contacting a source of position data if wireless network connectivity exists; and generating a data message to be sent via the wireless transceiver if the wireless network connectivity does not exist, the data message comprising an Internet Protocol (IP) address of the router, an approximate current location of the mobile geographic position aware receiver, and a request for correction data.
