<p>PROBLEM TO BE SOLVED: To provide a data transmission system, a synchronous data transmission apparatus and a synchronous data receiving apparatus capable of obtaining and synchronizing clock signals having almost the same frequency and phase between a data transmission apparatus and a data receiving apparatus which are respectively independently installed.SOLUTION: The data transmission system comprises: the synchronous data transmission apparatus including transmission side clock signal generation means for generating a transmission side reference clock signal to be a transmission side reference from a carrier wave received from a specified satellite through a transmission side antenna and data signal generation/sending means for generating and sending a data signal on the basis of the transmission side reference signal generated by the transmission side clock signal generation means; and the synchronous data receiving apparatus including receiving side clock signal generation means for generating a receiving side reference clock signal from a carrier wave received from the satellite through a receiving side antenna and data receiving/reproducing means for receiving a data signal sent from the synchronous data transmission apparatus on the basis of the receiving side reference signal generated by the receiving side clock signal and reproducing data.</p> |
