  • Patent number: 5727057
    Abstract: A method and system implementation for combining and accessing telephony numbering and geographical position so direct access to information, services and goods may be invoked through the use of various telephone networks. The existing telephone networks throughout North America and the world use standardized numbering plans for connecting to, or switching any subtended device to any other device within the network. The U.S. government has orbited a series of communication satellites which provide a signaling method for determining precise geographical location throughout the world. This system is called the Global Positioning System (GPS) and provides several levels of service. Each GPS satellite continually transmits a navigation location signal which may be received on the ground, sea, or in the air and when combined with signals from other GPS satellites used to pinpoint navigational position in two or three dimensions.
