Abstract
PURPOSE:To achieve a higher reliability, by comparing detection positions of a Loran receiver and an autonomous navigator to select between the both from a relationship between the resulting difference and a reference value. CONSTITUTION:A Loran receiver 4 is connected to a microcomputer MC2 and outputs a position data Pc detected and conditions signal Cc indicating ability/ disability of detection to the MC2. A position data Pm for initialization is provided to an autonomous navigator 8 from the MC2 while a position data Pn calculated with the device 8 is inputted into the MC2. When disability of detection is identified by the signal Cc, the data Pn of the device 8 is shown on a display 3. When the detection of the receiver 4 is judged to be possible, a difference DELTAP is computed between the data Pc and Pn. When the difference is below a specified reference value, the data Pc is displayed while the data Pn is displayed when it is below the value. This achieves a higher reliability of a system.
