The cJoy system
The Kongsberg Joystick system (cJoy OT) is a computerised steering control system
with manual, semi automatic and optional full automatic control capability.
This system integrates control of the vessel's propulsion systems in a single joystick
and has added features for automatic heading control and selection of vessel rotation
point. It also has, as options, automatic position control (station keeping) and steering
along a selected course (autopilot).
Vessel movement is manually controlled using the joystick. Tilting the joystick causes
the vessel to move in the fore/aft and port/starboard directions whilst rotating the joystick
causes the vessel to change heading.
When automatic heading control is selected, the vessel's heading is controlled
automatically based on measurements from a gyrocompass, while the vessel's position
is controlled manually from the joystick.
When automatic position control (station keeping) is selected, the vessel's position is
maintained at the current location based on measurements from a wind sensor, vertical
reference sensor and position-reference system.
Deviations from the desired heading or position are automatically detected and
appropriate adjustments are made by the system.
Basic forces and motions
A seagoing vessel is subjected to forces from wind, waves and current, as well as from
forces and moments generated by the vessel's propulsion system.
