Navigation aid method, device and program
First Claim
1. A navigation aid device, comprising:
- a calculation time setting module for setting two or more calculation points of time for calculating trial information;
a ship-concerned information acquisition module for acquiring ship-concerned information including a position of a ship concerned at every predetermined ship-concerned information acquisition time;
a ship-concerned trial information calculating module for calculating ship-concerned trial information including future positions of the ship concerned at the respective two or more calculation points of time based on the most-recently acquired ship-concerned information;
a display module for simultaneously displaying on a screen the future positions of the ship concerned so as to correspond to respective positions on the screen;
a target-object information acquisition module for acquiring target-object information including a position of a target object other than the ship concerned at every predetermined target-object information acquisition time; and
a target-object trial information calculating module for calculating target-object trial information including future positions of the target object at the respective two or more calculation points of time based on most-recently acquired target-object information;
wherein the display control module causes the display module to simultaneously display the future positions of the target object at the respective two or more calculation points of time, the future positions of the target object being displayed so as to correspond to respective positions on the screen.

19. A non-transitory computer-readable medium on which is stored a navigation aid program which, when executed by a computer, causes a computer to perform a process comprising:
-
inputting two or more calculation points of time for calculating trial information; inputting ship-concerned information including at least one of a position, a speed, and a bearing of a ship concerned at every predetermined ship-concerned information acquisition time; calculating ship-concerned trial information including future positions of the ship concerned at the respective two or more calculation points of time based on the most-recently acquired ship-concerned information; and inputting target-object information including at least one of a position, a moving speed, and a moving direction of a target object other than the ship concerned at every predetermined target-object information acquisition time; calculating target-object trial information including future positions of the target object at the respective two or more calculation points of time based on the most-recently acquired target-object information; simultaneously displaying on a screen the future positions of the ship concerned and the target object so as to correspond to respective positions on the screen; acquiring target-object information including a position of a target object other than the ship concerned at every predetermined target-object information acquisition time; and calculating target-object trial information including future positions of the target object at the respective two or more calculation points of time based on most-recently acquired target-object information; wherein the future positions of the target object at the respective two or more calculation points of time are simultaneously displayed on the screen, the future positions or the target object being displayed so as to correspond to respective positions on the screen.
