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.


Control Area Network (CAN)

Northrop Grumman Sperry Marine developed the first steering system using a Control Area Network (CAN). The CAN connects a various number of steering controllers, including the Autopilot Control and Display Unit into a network. With this, the installation is made far more simple and fast. Also, later extension of the system is very simple.


Override for Evasive Manoeuvres

Override is a means to immediately take control of the steering in the event that an evasive manoeuvre is necessary or a malfunction occurs at the autopilot. When activated, the control is transferred to the Override Non-Follow-Up Controller and the vessel is steered in manual control (non-follow up), until the Override mode is ended by the operator.

Safety and Efficiency 
Northrop Grumman Sperry Marine’s NAVIPILOT 4000 is a highly reliable ship automation system that ensures fuel savings, operational safety and efficient steering.
The innovative Autopilot is designed to learn your vessel’s steering characteristics, allowing for real-time, dynamic adjustments to make the ships steering more accurate and efficient. The continuous self-tuning adaptation is unique compared to all other autopilots in the industry.
