Abstract
A navigation system for a marine vessel is provided. The navigation system includes a locating system configured to locate a global position of a center of rotation of the marine vessel and a transducer configured to sense water depth measurements. The transducer is positioned a longitudinal distance and a lateral distance from the center of rotation. The navigation system further includes a controller configured to receive the water depth measurements and to determine an adjusted transducer position relative to the center of rotation based on the longitudinal distance, the lateral distance, and at least one of pitch or roll movements of the marine vessel. The controller is further configured to correct the water depth measurements based on the pitch or roll movements of the marine vessel and to determine a chart error correction value based on the adjusted transducer position and the corrected water depth measurements.
