In addition, the segment number of the azimuth marker 114 sent from the data conversion unit 24 (the segment number is configured such that the azimuth marker 114a facing upward is numbered 0, and the value is increased by 1 in the clockwise direction). Then, the corresponding direction marker 114 is turned on. At this time, the direction marker 114c indicating the target local position is turned on and off repeatedly every 1 second, and the direction marker 114b indicating the heading direction is continuously turned on. It is indicated so that it can be distinguished from the target locality. Further, when the heading and the target region are the same heading marker 114, only the heading is displayed (continuous lighting display).

When the user display mode is selected by the input of the keyboard 29, the declination calculator 25 calculates declination data indicating the difference between the destination region position output 23a and the heading direction output 21b, and the data is calculated. It is sent to the conversion unit 24. Therefore, the data conversion unit 24 sends the declination data calculated by the declination calculation unit 25 and the segment number of the azimuth marker 114 corresponding to this data to the display control unit 26. The display control unit 26 displays the value of the declination by the numerical segment 115d at the center of the omnidirectional display 11 and lights the azimuth marker 114d corresponding to the declination. At this time, the values displayed by the numerical segments 116 to 122 are, from the top to the bottom, the effective speed of the destination, the time required to reach the destination, the estimated arrival time, the destination identification number, and the latitude of the ship's position. And longitude.

The present invention is not limited to the above-described embodiment, and the case where the directional marker 114 is formed by 32 markers has been described. However, as another configuration, for example, 60 directional markers are formed. It is possible.

As for the display unit 10 on which the omnidirectional display 11 is displayed, the case where a liquid crystal display is used has been described, but other display units such as a CRT display unit can be used.

As a method of distinguishing the direction marker indicating the target region and the direction marker indicating the heading on the omnidirectional display 11, one direction marker is blinking and the other direction marker is continuously lit. Although the case has been described, as another configuration, for example, two orientation markers may be displayed in different colors.

Further, the case where the GPS navigation device 21 is used as the navigation device has been described, but the same can be applied to the case where another navigation device such as a Loran navigation device is used.

As described above, in the present embodiment, since the configuration in which the destination region position and the heading direction are simultaneously displayed on the omnidirectional display 11, it is possible to grasp the situation with respect to the heading during navigation. It's pretty easy.
