navipilot 4000

Ships are steered safely and efficiently with the NAVIPILOT 4000 Marine Autopilot advanced ship steering control network technology.

The innovative NAVIPILOT 4000 is capable of tuning itself to adapt automatically to the ship's load characteristics and weather conditions.

Key benefits of NAVIGAT 4000 Marine Autopilot include:

  1. Fully self-tuning, adaptive heading control
  2. Manual selection of steering strategy to suit weather conditions
  3. Rate and radius control modes
  4. Meets the requirements of all major classification societies
  5. Ease of use with logical arrangement of sealed foil keyboard

Efficient fuel consumption

The highly reliable NAVIPILOT 4000 ensures continuous self-tuning adaptation for accurate steering and efficient fuel consumption, which is unique to all other autopilots in the marine industry.

Each single rudder activity increases fuel consumption and cost. For this purpose the NAVIPILOT 4000 can adapt automatically to the current weather and sea conditions.

Track control

Track Control (also referred to as 'Tracksteering') combines an ECDIS with the Autopilot. The navigator can program a voyage plan into the ECDIS that contains one or more tracks. Track Control with a NAVIPILOT 4000 marine autopilot is type-approved (category B/C) when connected to a Northrop Grumman Sperry Marine VisionMaster FT ECDIS.

The autopilot system receives its orders from the Northrop Grumman Sperry Marine ECDIS and transmits steering commands to the steering system. The orders may be manual changes of wanted heading, turn radius or rate of turn or it may be orders originating from track control along a selected route. Together with Northrop Grumman Sperry Marine Bridge ECDIS and Conning Information Display, the Integrated Bridge Autopilot forms a complete system for automatic track control.
