A loran navigation receiver for measuring and indicating values of position-coordinates (values of time difference [LOP] or values of latitude and longitude). This receiver is equipped with an indicator which can give only an indication of either one position-coordinates. The indicator has a function of indicating simultaneously, as a series of digits, lower order digits in both the value-numbers of the two position-coordinates and a function of alternatively changing-over, manually or automatically, to indicate each of the value-numbers of the two position-coordinates in its full digits. |
