Abstract : An audio information apparatus for providing position information as to the location 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.
