System principles ......................11 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.
Page 10
Kongsberg cJoy OT The term “forces” in the following sections includes both forces and yawing moments, unless otherwise stated. The vessel's responses to these forces are measured by a gyrocompass, vertical reference sensor and position-reference system. Position-reference system readings are corrected for pitch and roll using readings from the vertical reference sensor.
This information is received from the vertical reference sensor. System principles A simplified block diagram of the cJoy OT system is shown in Figure 3, and described in the sections that follow. Figure 3 cJoy OT system block diagram...
Kongsberg cJoy OT The Kalman Filter The Kalman Filter estimates the vessel's heading, position and velocity in each of the three degrees of freedom - surge, sway and yaw. It also incorporates algorithms for estimating the effect of sea current and waves.
System overview • In the absence of position measurements, the model provides a “dead-reckoning” mode. This means that the system is able to perform positioning for some time without position updates from a position-reference system. In the Kalman Filter, the Mathematical Vessel Model's reliability and the noise level of the position measurement are the basis for deciding how much to trust each measurement.
Kongsberg cJoy OT Thruster allocation The force demand in the surge and sway axes (the force setpoint), and in the yaw axis (the turning moment setpoint), is distributed to the various thrusters and propellers by the Thruster Allocation function. These setpoints are distributed in such a way as to obtain the force and turning moment...

Operating procedures Enabling thrusters When a thruster can be enabled for joystick control, it is shown as Running Ready on the Thruster view (see Thruster view on page 36) and on the Thruster Enable input dialog (see Thruster Setup on page 47). There are generally two criteria for a thruster status: Ready...
Kongsberg cJoy OT For the azimuth thrusters, you can choose between various thruster allocation modes. The currently-selected thruster allocation mode is shown in the field of Thruster Alloc the General Setup input dialog. Depending on the operational mode, illegal thruster allocation modes are unavailable in the General Setup input dialog.
Operating procedures This minimum RPM is a limit which defines the lowest RPM that the thruster propeller will be allowed to rotate in either of these two modes. For example, if the minimum RPM is set to 60% then the range for the thruster propeller RPM will be set to 60 to 100%, i.e. the thruster propeller will not be allowed to rotate at less than 60% of its maximum RPM.
Kongsberg cJoy OT Gyrocompasses At least one gyrocompass should be enabled at all times to provide heading information to the system for automatic control of heading. Rejection of heading measurements Normally, all available gyrocompasses will be running and enabled for use.
Operating procedures Disabling a gyrocompass To disable a gyrocompass, proceed as follows: Display the Sensor Enable input dialog. Move the focus to the field for the gyrocompass and change the option to Enable If the optional Autopilot mode is available and if required, repeat step 2 for the other gyrocompass.
Kongsberg cJoy OT Normally, input from the wind sensor will be enabled. The system then receives and compares the signal from the sensor and uses it to calculate the wind force acting on the vessel. The raw measurements of wind speed and direction are filtered internally (using a Kalman filter with both low and high frequency parts), to estimate the most reasonable speed and direction values to be used by the system.
Operating procedures To avoid this, the system performs the following test: • A wind speed measurement is rejected by the system if the wind speed is above a predefined limit (for example 15 m/s) and increases by more than a predefined value (for example 10 m/s).
Kongsberg cJoy OT Displayed VRS information You can examine the status and measured values for the vertical reference sensor on the Sensor view (see Sensor view on page 38). Enabling the VRS To enable the VRS, proceed as follows: Display the Sensor Enable input dialog.
Operating procedures In high speed operations (e.g. in the optional Autopilot mode) all enabled speed sensors will normally be in use (unless a sensor has failed) when speed measurements are used by the system. It is recommended to also enable manual speed input since the manual value will be updated based on the in use sensors.
Kongsberg cJoy OT • If a high speed operation is selected the field changes to green. Manual SPD Close the Sensor Enable input dialog. Disabling a manual speed value To disable a manual speed value, proceed as follows: Display the Sensor Enable input dialog for speed sensors.

Operating procedures • A prediction test detects sudden jumps or large systematic deviations in the measured position. The limit for the prediction test is a function of the estimated position in the Vessel Model and the actual measurement accuracy. If the results of the variance and prediction tests suggest that the position measurements from the reference system are not accurate, then the measurements are not used.
Kongsberg cJoy OT Reference high variance You should disable the position-reference system if the event of high variance is recurring. No corrective actions are necessary if the problem is intermittent only. Prediction test The prediction test detects sudden jumps in the measured position, and immediately rejects those that lie outside the limits as illustrated in Figure 18.
