Filed: 1979-02-02
Abstract: PURPOSE:To ensure the accurate measurement for the geographical location of the reception point by receiving the color TV broadcast waves sent from the transmission points of the several known positions and then giving the comparison to the phases of the demodulated waves. CONSTITUTION:Receivers 1 and 2 receive the color TV broadcast waves of the same contents transmitted from different points. And the control is given to variable phase unit 3, and the output of phase detector 4 is turned to 0. Thus the difference of the signal transmission can be calculated between receivers 1 and 2. Accordingly, if the geographical locations of the transmission points are known along with the time difference of the radiated electric waves, the difference of the transmission time can be known. Thus the distance difference can be calculated from the reception point to each transmission point. Furthermore, the broadcast waves of more than three stations are used, thus ensuring accurate decision for the geographical location of the reception point.
