Abstract
A system for providing position-related information to a mobile user includes a central site server and mobile unit that has circuitry for allowing a user selection and for receiving position signals that may emanate from, for example, GPS satellites. The mobile unit further includes circuitry for establishing a wireless bidirectional communications link with the central site server via a terrestrial network such as a cellular telephone network, and sending position information and selection signals to the central site server. The central site server includes circuitry for receiving the present position information and selection signals selected by the user. Responsive thereto, the central site server retrieves corresponding response information, which is sent to the mobile unit via the bidirectional communications link. In one embodiment, communications between the mobile unit and the central site server are encrypted.
