Abstract (en)
[origin: WO2004105407A1] A GPS microphone, which is adapted for incorporating a communication system, includes a speaker-microphone set (10), a radio frequency transmitter (20) communicatively networked with the communication system through radio frequency signals, and a GPS controller (30) electrically connected with the radio frequency transmitter to encode positioning data into one or more RF positioning signals in form of audio signals wherein when the GPS controller is triggered, the radio frequency transmitter is activated to transmit RF positioning signals to the communication system.
