Outputs dummy azimuth data corresponding to the dummy azimuth signal SDdj. The CPU 77 sends the dummy azimuth data to the LAN / I / F circuit 59 shown in FIG. Output to

Thus, the control unit 45 shown in FIG.
U52 converts the input dummy azimuth data into bus B

That is, when the integrated operation unit 74 is used, the dummy gyro data (dummy direction data), the dummy sound wave log data (dummy ground speed data), the dummy electromagnetic log data (dummy water speed data), and the dummy gyro data shown in FIG. Dummy wind direction /
Backup by wind speed detection data (dummy wind direction / wind speed data) is possible.

Furthermore, in the navigation support apparatus according to the above-described embodiment, an example has been described in which backup is performed by using dummy data when a navigation information measurement apparatus (such as the GPS receiver 33) fails. Dummy data may be used instead of the actually measured value. In this case, since the measuring device (the GPS receiver 33 and the like) is not required at the time of the inspection of the device, the inspection can be easily performed.
