Title:
AUTONOMOUS NAVIGATION GUIDANCE DEVICE
Document Type and Number:
Japanese Patent JPH0363523
Kind Code:
A
Abstract:
PURPOSE:To enable course deflection which has no overshoot by providing a data processor, an operation indication device, a navigation data input device, a current ship position measuring instrument, a gyrocompass, a ship speed detection log, and an automatic steering device. CONSTITUTION:Waterway data are inputted as an enumeration of course deflection points in longitude and latitude from a data input device 3 to a data processor 1 and ship position data are inputted momentarily from the position measuring instrument 4 such as a satellite navigation device or radio navigation device, so that the distance (d) to a next course deflection point is calculated according to those data. On the other hand, course data and ship speed data are inputted from the gyrocompass 5 and log 6 respectively and control parameters are inputted from the automatic steering device 7, so that a new course distance D is calculated according to those data. Consequently, the large/small relation between the distances (d) and D is monitored continuously and when d <=D, a course deflection start warning and a new course are outputted to the operation indication device. This new course is sent to the automatic steering device 7 to perform course deflection.
