1. A GPS communication apparatus for transmitting a positioning data to a communication system, comprising a GPS microphone which comprises:
- a speaker-microphone set which comprises a microphone, a speaker, and a PTT (Push-To-Talk) circuitry arranged in such a manner that when said PTT circuitry is triggered to activate said microphone in a transmit mode, said microphone is capable of receiving and encoding a voice message into an audio signal;
a radio frequency transmitter communicatively networking with said communication system through radio frequency signals, and a GPS controller electrically connected with said radio frequency transmitter to encode positioning data into one or more RF positioning signals in form of audio signals, wherein when said GPS controller is triggered, said radio frequency transmitter is activated for transmitting said RF positioning signal to said communication system, wherein said GPS controller is activated when said PTT circuitry is triggered in such a manner that said audio signal from said speaker-microphone set and said RF positioning signals from said GPS controller are combined to form an information signal for transmitting to said communication system.
