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 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.
