SYSTEMS AND METHODS FOR COMPUTING AND DISPLAYING NAVIGATION INDICATORS BASED ON HISTORIC AND REAL-TIME VESSEL DATA

System and methods for computing true wind and true current are described. True wind estimation occurs through automatic calibration of data obtained from data acquisition devices (102, 114, 116, 118, 120).

More Information
Summary:System and methods for computing true wind and true current are described. True wind estimation occurs through automatic calibration of data obtained from data acquisition devices (102, 114, 116, 118, 120). Real-time boat performance information is generated through automatic target speed computation. Maneuvers are found in data obtained from the data acquisition devices (102, 114, 116, 118, 120) and, if properly calibrated, wind just prior to a maneuver should be the same as measured wind just after the maneuver. If the measured wind values are not equal, the sum of the wind difference over all maneuvers is minimized.
