The NAVIGUIDE 4000 Manual Steering System has multiple configurations to meet specific customer requirements and is fully type approved by classification society Germanischer Lloyd.
Key Benefits:
The NAVIGUIDE 4000 marine steering system has the following benefits:
- Network based steering control
- Flexible modular design: easy to expand/modify and suitable for all types of vessels
- Cost saving due to easy installation and commissioning
- High accuracy steering with multipoint calibration of rudder order and feedback signals
- Customised Steering consoles
Simple and Cost Effective
NAVIGUIDE 4000 components have a modular mechanical design that allow for simple installation, to fully meet customer requirements.
Northrop Grumman Sperry Marine offers customised console frames in different sizes and configurations. These frames are all pre-wired, configured and fully tested by Northrop Grumman Sperry Marine.
With the expertise of Northrop Grumman Sperry Marine installation, costs and commissioning time are considerably reduced.
Control Area Network
Northrop Grumman Sperry Marine was the first supplier to use Control Area Network methods. The NAVIGUIDE 4000 is connected to the Control Area Network (CAN) and power supply. The wiring of this system is less error-prone compared to other conventional systems. The NAVIGUIDE 4000 can connect a various number of steering controllers, including the autopilot NAVIPILOT 4000, into a network. The installation is simple and fast and extensions are easily to add.
Advanced Steering System
The NAVIGUIDE 4000 advanced marine steering system consists of modular system architecture and fulfils individual customer requirements. It can be used for all vessels with single and dual rudders and on vessels. Dynamic positioning and joystick systems can be integrated seamlessly. The system can even be modified or extended by simply adding components to the CAN bus.

Configurations
NAVIGUIDE 4000
Based on the control area network, the Ship Steering Control Network forms the backbone of the Control System, which is one of the first to implement the U.S. National Marine Electronics Association (NMEA) 2000 Data Communications standard.
NAVIGUIDE 4000 Follow-up (FU)/Non-Follow up (NFU)
Follow-Up and Non Follow-Up configurations are available for the NAVIGUIDE 4000. The different steering gear control system configurations are described as follows:
Non-Follow-up: (NFU)
NFU Steering control is the cost-effective and safest means of steering control, but not very comfortable. The rudder moves as long as the NFU-Tiller is operated and stops, when the tiller is released or the rudder limits are reached.
Follow-up (FU): (autopilot & manual)
The rudder follows the preset angle (rudder command) of the FU Handwheel and stops when this is reached. FU steering is a control of the rudder angle. It requires a Steering Control Unit (FU-amplifier) and a feedback unit in addition to the Handwheel. FU steering is more comfortable/user-friendly than NFU.
Dual Follow-up
Dual Follow-up provides separated controls to each steering gear by means of two SCUs, each controlled by a separate potentiometer of the FU-Handwheel. A single failure only causes a loss of control of one steering gear. Dual FU is mandatory with certain classification societies or notations.
It is mandatory by IMO/SOLAS to have two electric steering gears that are completely independent, also with regards to the power supply. Usually, there are two separate steering gears, each with its own steering pump, solenoid valves etc.
Rudder Angle Indicator
NAVIGUIDE 4000
The Rudder Angle Indication system is separate to the steering system and is for indication only. It is an IMO requirement to have this system independently from the steering control system. Rudder angle indication is required for each steering position and at the emergency steering position in the steering gear room.
The different regulatory bodies vary on the requirements on the Rudder Angle Indicators (RAI). DNV requires a second, independent rudder angle indication system on the bridge. Panama Canal regulation requires large instruments (192x192mm minimum) on the bridge wings, visible for the pulling train operators and the IMO/MED (ISO 20673) requires the accuracy of the system to be above 1 degree.
Rudder Angle Indicators for Every Need
Northrop Grumman Sperry Marine rudder angle indicator systems are characterised by a diversity of different indicators, to fulfil the individual customer needs and regulations. The Rudder Angle Indicators are in different sizes, scales, type of installations and protection grades. In addition three-face rudder angle indicators with a 270° panoramic indication are offered.
Rudder Angle Calibrator
To meet IMO regulations for accuracy, Northrop Grumman Sperry Marine developed the Rudder Angle Calibrator (RAC). This is the central unit of the RAI system that provides NMEA outputs with the rudder angle, for Voyage Data Recorder and/or ECDIS/Conning Display.
A total of 6 indicators can be connected to each RAC, including the feedback unit and each can be calibrated separately. Where there are more than 6 indicators, an additional Rudder Angle Calibrator is required.
