Abstract

Abstract A Global Positioning System (GPS) communications includes a GPS receiver for generating position information, a processor coupled to the GPS receiver by a bus, and a communications multi-interface coupled to both the GPS receiver and to the processor by the bus. The processor presents the position information to the communications multi-interface capable of interfacing with a wide variety of communications systems. Described applications include guided weapons systems, interrogatable tag systems, collision avoidance systems, remote locator/responder systems, beacon location systems, search and rescue transceiver systems, location reporting pager systems, and cellular telephone location systems.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 144 words
A Global Positioning System (GPS) communications multi-interface capable of interfacing with a plurality of communications systems, the GPS communications multi-interface comprising: a GPS receiver for generating position information: a processor coupled to the GPS receiver by a bus; and a communications multi-interface coupled to both the GPS receiver and to the processor by the bus, wherein the processor presents the position information to the communications multi-interface and wherein the communications multi-interface comprises: a status/configuration determiner having a status/configuration input/output; a two-tone modem interface having a receive, transmit audio input/output; a serial digital interface having a serial digital input/output; a multi-tone modem interface having a multi-tone input/output; a bus parallel interface having a bus parallel input/output; and a common controller coupling each of the status/configuration determiner, the two-tone modem interface, the serial digital interface, the multi-tone interface, and the bus parallel interface to the bus.
Claim 2
Dependent Claim 144 words
A Global Positioning System (GPS) communications multi-interface capable of interfacing with a plurality of communications systems, the GPS communications multi-interface comprising: a GPS receiver for generating position information: a processor coupled to the GPS receiver by a bus; and a communications multi-interface coupled to both the GPS receiver and to the processor by the bus, wherein the processor presents the position information to the communications multi-interface and wherein the communications multi-interface comprises: a status/configuration determiner having a status/configuration input/output; a two-tone modem interface having a receive, transmit audio input/output; a serial digital interface having a serial digital input/output; a multi-tone modem interface having a multi-tone input/output; a bus parallel interface having a bus parallel input/output; and a common controller coupling each of the status/configuration determiner, the two-tone modem interface, the serial digital interface, the multi-tone interface, and the bus parallel interface to the bus.
