Audio information apparatus for providing position information

An audio information system for determining a present location, said audio information system comprising:

• a global position system receiver for providing electrical signals representative of a plurality of ASCII data characters, said plurality of ASCII data characters including latitude and longitude spherical coordinates indicative of the present location of said global position system receiver and a first checksum;
• an optical coupler coupled to said global position system receiver for receiving said electrical signals and converting said electrical signals to a serial digital format:
• a microprocessor coupled to said optical coupler for receiving said electrical signals converted to said serial digital format by said optical coupler, converting a predetermined number of said electrical signals received thereby to a plurality of binary addresses representative of said latitude and longitude spherical coordinates, calculating a second checksum and generating a play signal;
• said microprocessor comparing said first checksum with said second checksum, said microprocessor setting a do not transfer flag whenever said first checksum is not equal to said second checksum;
• a NAND gate having a first input for receiving a logic one, a second input coupled to said microprocessor for receiving said play signal and an output;
• said NAND gate inverting said play signal to provide an inverted play signal;
• a digital voice module coupled to said microprocessor and the output of said NAND gate for receiving said inverted play signal, said digital voice module receiving said plurality of binary addresses from said microprocessor whenever said microprocessor does not set said do not transfer flag, said digital voice module, responsive to said plurality of binary addresses and said inverted play signal, generating an analog audio voice signal representing said latitude and longitude spherical coordinates;
• a two position switch having an input connected to said digital voice module, a first output and a second output;
• a transmitter coupled to the first output of said switch for receiving said analog audio voice signal through said switch from said digital voice module, said transmitter having an antenna, said transmitter responsive to said analog audio voice signal providing a plurality of position messages at a predetermined frequency, said position messages including said latitude and longitude spherical coordinates;
• said antenna transmitting said plurality of position messages at said predetermined frequency to provide an indication of the present location of said global position system receiver;
• and
• a speaker connected to the second output of said switch for receiving said analog audio voice signal through said switch from said digital voice module, said speaker means, responsive to said analog audio voice signal broadcasting position information, said position information including said latitude and longitude spherical coordinates indicative of the present location of said global position system receiver.
