Overview

NJoy our newest generation of Joystick control system. System features manual control of engines and thrusters with single joystick as well as automatic position keeping.

Despite having same functionality and operation philosophy, NJoy is not a full scale dynamic positioning system. It is designed to be operated by navigator offering much more simple control comparing to DP. 

This solution is the best for small work boats and yachts, which require smart and intelligent automatic functions with combination of precise manual control but without complicated DP GUI or DP certification.

  • Can be with integrated type approved autopilot
  • No UPS
  • Auto functions based on fast and precise DP algorithms
  • Type approved Autopilot could be integrated part
  • One control panel for both: Autopilot and NJoy systems
  • Same sensors for Autopilot and NJoy systems
  • Compact
  • Remote support and fine tuning
  • No big touchscreen required
  • Simple and intuitive GUI
  • Panels could be installed under solid foil or glass


Typical applications where this system proves to be very useful:
  • Survey boats
  • Fire fighting boats
  • Coast guard boats
  • Wind farm crew transfer vessels
  • Fish farm service vessels
  • Work boats

M.Sc.E.E., Ph.D.: 

«The Product: The NAVIS AP and Joystick control system has a very user friendly appearance, its user interface is easy to learn, and the product operation and handling of the vessel is of outstanding quality. 

The Operation: The Autopilot enables operation in a number of modes of great usefulness for the daily operation of the ship.  Being harbor maneuvers, sailing in narrow channels, anchoring in areas with strong wind or current, it operates flawlessly.  Operations in JP modes are extraordinary and very convincing.

The Team: The NAVIS installation and service team is among the most efficient and the fastest handling we have experienced.  User interaction is friendly and expedient. Response time is very fast». 

System Highlights

  • Analogue interface: 16 DI, 16 DO, 16 AI, 8 AO 

  • 8 RS422 sensors + 1 dual RS port

  • 2 PCP connection points or 2 additional control panels only

  • DGPS

  • GYRO (Heading)

  • Wind sensor

  • … nothing else, no VRS required

Control modes

APH7 autopilot screen_Joystick.png

Standby mode

Ship Control is provided from the Bridge Control Console, using engine telegraph levers, thruster control levers and steering levers or wheel. The system is in operation and is ready for control acceptance.

Joystick Manual Control (Jman)

The surge/sway forces and the yaw moment are controlled manually by using the joystick/knob.

• Adjustable joystick gain (sensitivity)








Joystick Auto Position & Heading (Jpos)

Automatic keeping of the operator selected vessel heading.
• Hold the vessel heading
• Set new heading: absolute value or offset from the previous set-point
• Set rate of turn
• Adjustable heading controller gain
• Heading deviation alarm with adjustable limit

Automatic keeping of the operator selected vessel position.
• Hold the vessel position
• Set new position as offset from the previous set-point
• Set transfer speed
• Adjustable position controller gain
• Position deviation alarm with adjustable limit

Joystick Speed Control (Jspd )

Joystick Speed Control (Jspd )

Automatic keeping of the operator selected vessel speed vector.

• Hold the vessel speed
• Set new speed (digital/joystick input)
• Adjustable speed controller gain







Joystick Eco Positioning (JEco)

Automatic keeping of the operator selected area with optimal heading directed against disturbing force (wind and/or current) to minimize power consumption of propulsion.







Joystick Anchor (JAnc)

The System automatically searches and sets an optimal heading directed against disturbing force (wind and/or current) to minimize yawing by means of only stern propulsion.






 




Thrust Allocation 

At any given moment the fore-aft and athwart ships forces and rotary moment, which are necessary for ship position and heading control, are calculated.
  • Thrust Limits
  • Thrust Configuration

Auto Wind Compensation

When this function is selected, control forces and moments are generated to compensate for wind disturbance.


Alarm System

The built-in alarm generating system includes online diagnostics, message reporting and alarm acknowledgement function.

  • Alert Status System
  • (red, yellow, green)
  • Voice Alarms
  • Online Diagnostics
  • Message Reporting
