Heading Control System

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 18 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 com- pany'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. The AP4000 Heading Control System is the new generation of autopilots manufactured by Navis...

Operator station review The modular concept of the AP4000 control panel makes it possible to integrate the autopilot into any bridge console without causing any harm to the overall design. The autopilot is frame-mounted, which allows the control panel to be detached from the bridge console easily, in case Compared to the previous generation's autopilot, the level of the control panel's front surface protection has been increased from IP44 to IP67, which makes the AP4000 suitable for outdoor installations (at fy-bridge or port/starboard The reduced number of buttons ensures prompt and easy...

System overview As compared to the AP3000, the software part of the AP4000 has been upgraded significantly. Up to five network control panels have been added to functionality. The use of only one 'Sensitivity' parameter for fine-tuning system per- formance covers all known yawing, steering and counter rudder settings of the autopilots of other brands. The AP4000 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, gyro+fluxgate etc.). Several speed...

Control modes Three more control modes have been added to those present in the previous generation of the AP4000: the'CTS Pilot' control mode, which allows for steering by a pre-set COG value, the'Windvane'mode for sailing yachts, making it possible to steer by setting the relative wind angle, and the'River Pilot'mode, allowing the operator to steer the vessel by a pre-set ROT value using an external ROT tiller or the knob in the control panel. The following control modes are available: Auto Track/AutoNav In the'Auto'mode the ship heading is controlled au- In the'Track'mode the AP4000...

Control modes Dodge/FFU Override/FFU In 'Dodge'/'FFU'/'FFU Override' modes the heading can be corrected manually using the external over- ride devices (rotary knob on the AP4000 control panel, override tiller, jog lever, etc.). These modes are optional. | INFO: SET RUDDER: 15° PORT FEEDBACK: 10° PORT | STBD[> STBDM |lNFO: SET RUDDER: 15° PORT FEEDBACK: 10° PORT Windvane (for sailing yachts) The 'Windvane' mode allows for steering the sailing yacht by setting the relative wind angle.
