<p>PURPOSE:To securely evade a collision against another ship by calculating information on the ship from the detection signal of a radar, etc., predicting the future movement of the ship on the basis of marine chart information, etc., and displaying the dangerous range of a collision against this ship. CONSTITUTION:The opposite-ship information on the position, speed, and course of the opposite ship is calculated 2 on the basis of the detection signal obtained by a ship peripheral state searching device 1 such as a radar and a sonar. Then, marine chart information 8 on a waterway, a sunken rock, etc., and the marine traffic rule 7 are inputted together with the opposite ship information and the future movement of the opposite ship is estimated 3. Then, the dangerous range of a collision is calculated 4 from the future movement and the condition of this ship and the arithmetic result is displayed graphically 5. Consequently, safe navigation is possible.</p> |
