Abstract

PURPOSE:To accomplish the lane display for each station at any time with the use of a simple construction by dividing the frequencies of omega signals to regulate in advance the time relationship between the divided frequencies so that the lane number and phase difference between the omega signals are measured. CONSTITUTION:Omega signals a,b,c and so on of respective stations, which have different phases, are received to regulate in advance the phase difference of the received signals to preset times of the period T of the signals a,b,c and so on corresponding to the lanes of the time relationships between the stations thereby to generate the divided waves a1 to a3, b1, c1 and so on. If the time differences of those divided waves a1 to a3, b1, c1 and so on are measured, the lane number and the phase difference between the respective omega signals are displayed at any time with the use of a simple construction dispensing with a number of memory devices and discriminating devices according to the combinations of the stations so that the moving condition of a ship on a chart can be discriminated and displayed.
