NAVIS NavAP Heading Control System

Introduction Navis Engineering, established in 1992, is a recognized expert in ship automation systems and one of the few world experts in dynamic positioning technology. After more than 25 years of scrupulous research and development, we have cultivated a profound understanding of every customer’s needs, as well as of market trends in shipbuilding. Our company’s mission is to keep our systems as simple and user-friendly as possible, and, at the same time, to preserve the high level of quality and reliability. Navis Engineering manufactures the new generation of autopilots – NavAP Heading...

System overview The NavAP is fully adaptive. The use of only one ‘Sensitivity’ parameter for fine-tuning system performance covers all known yawing, steering and counter rudder settings of the autopilots of other brands. The NavAP has built-in ‘Heading Monitor System’(HMS) functionality, which makes it possible to receive and monitor the data coming from two heading data sources continuously (gyro+gyro, gyro+magnetic compass, atellite gyro etc.). Several speed sources can also be used during operation (GPS, waterspeed log or bottom tracking log). The NavAP fully self-adjusting ‘Auto Tune’...

Operation modes Auto The NavAP automatically keeps the set heading on high and low speeds. The low-speed heading mode can be used by means of 1 or 2 thrusters connected to the NavAP. Track The NavAP controls vessel motion on straight legs between track points set from chart system. FU Follow-up manual control of the steering systems using the rotary knob on the control panel or via an external FU lever/wheel. CTS Pilot The NavAP automatically keeps the set course (COG). River Pilot Manual Rate of Turn (ROT) control using the rotary knob on the control panel or via an external ROT tiller....
