  • Patent number: 5552993
    Abstract: An audio information apparatus for providing position information as to the ocation of a target comprising a global positioning system receiver affixed to the target for generating a string of fifty nine ASCII characters representing the latitude and longitude spherical coordinates of the global positioning receiver affixed to the target. The ASCII characters are supplied to a microprocessor, which in response to the ASCII characters, formulates a position message indicating the current location of the global positioning system receiver. A pair of voice recorder/playback circuits, coupled to the microprocessor, have a message table which includes 27 messages or words which when assembled in a predetermined sequence form a longitude and latitude coordinate position message.

  • Patent number: 5495416
    Abstract: An audio information apparatus for providing position information as to the ocation of a target comprising a global positioning system receiver affixed to the target for generating a string of fifty ASCII characters representing the latitude and longitude spherical coordinates of the target. The fifty ASCII characters are supplied to a microprocessor which converts a predetermined number of the fifty characters to a plurality of a four bit addresses. The four bit addresses are supplied to a digital voice module which generates an analog audio voice signal in response to the four bit addresses. The analog audio voice signal which represents the location of the global positioning system receiver is supplied to a speaker. The speaker then broadcast the exact location of the global positioning system receiver. The analog audio voice signal is also supplied to a transmitter for transmission of the signal to a ground station.
