A GPS microphone, which is adapted for incorporating a communication system, includes a speaker-microphone set, a radio frequency transmitter communicatively networked with the communication system through radio frequency signals, and a GPS controller electrically connected with the radio frequency transmitter to encode a positioning data into a RF positioning signal in form of audio signal wherein when the GPS controller is triggered, the radio frequency transmitter is activated to transmit RF positioning signal to the communication system.
