1. A simulcast transmission system having means for time synchronizing the transmission of data signals therefrom, comprising:

  • a control station comprising first time generating means for generating system timing signals and for transmitting the same, means for receiving the transmitted system timing signals, means for comparing the transmitted and received system timing signals to generate a time correction factor signal in response thereto, and means for distributing the time correction factor signal to a plurality of transmission stations; and

    each of said plurality of transmission stations comprising second time generating means for generating local timing signals, means responsive to local timing signals for transmitting the data signals, means for receiving the transmitted system timing signals, means for receiving the time correction factor signal, means for comparing the received system timing signals and time correction factor signal with the local timing signals to generate a time adjustment factor signal, and means responsive to the time adjustment factor signal for adjusting the timing of said second time generating means.
