APPARATUS FOR AUTOMATIC CONTROLLING RADIO FREQUENCY USING GROBAL POSITIONING SYSTEM

摘要

PURPOSE: By automatically varying the radio frequency for region the radio frequency apparatus of auto adjusting using the GPS(Global Positioning System) eliminates to troublesome of listener. CONSTITUTION: A tuner(2) receives a message the broadcast signal according to the selected frequency value. Tuner outputs the audio signal by demodulating the broadcast signal. By receiving a message coordinate data and transmitted time data by the GPS satellite the GPS receiver(10) on a real time basis measures the current position. A memory unit(16) stores the circular region planning area frequency value of each broadcast station.
