GPS DEVICE FOR DETECTING FISH SHOAL

摘要

PPROBLEM TO BE SOLVED: To solve the problem of conventional navigation equipment, wherein the decision in the direction of advance using the depth as a criterion is forced to be based on the information from a display screen, since not only the past seabed to a position which a ship has reached at the present point is displayed, but also a stretch between indistinct points is coupled by a segment. PSOLUTION: A GPS receiver 2 is connected to a GPS antenna 1, and a position information detecting part 3 is connected to the GPS receiver 2; a position information memory 4 is connected to the position information detecting part 3, and an azimuth-ship speed computing part 5 is connected to the position information memory 4; an output of the azimuth-ship speed computing part 5 and an output from a map data output part 6 are inputted to a map depth data detecting part 7; moreover, an output of the map depth data detecting part 7 is inputted to an anticipated seabed image preparing part 8; and the output of the forecasted seabed image preparing part 8 is stored in a memory 9 for an image.
