s 

The operator can choose navigation sensors to use for navigation and view their current values on the Sensors dialog 
box. To access this dialog box, put the cursor on the Position field in the information area then push the right button.  

Checkbox status shows whether a sensor is used for integrated navigation or not. If there is no value shown for a 
sensor this means that the sensor is not valid. Note that the content of these pages depends on sensors that are in use 
on the ship.  

Manual speed: If checked, user can enter value (kn) for 
speed. 

Note: This is used only if there are no other speed or 
SOG sensors chosen. 

Log: If checked, a log is used as water speed source. 

Note: If you have a dual-axis doppler log that can 
measure both water and bottom track, then installation 
parameters can be set to receive water tracking as log 
device. 

Dual log (water): If checked, a dual log is used as 
speed and course source. "(water)" is used to indicate 
that this information is from water track of dual log. 

Dual log (bottom): If chosen, a dual log is used as 
speed and course source. "(bottom)" is used to indicate 
that this information is from bottom track of dual log. 

Ref tgt: Speed according to reference target. 

Gyro 1: Heading source is a gyrocompass. "(mag)" 
means the source is magnetic heading. True heading 
source has no indication. If the source of Gyro1 is a 
gyro with synchro or stepper interface, the indication 
"(require set)" appears when you need to set a new 
initial value for the gyro. 

Rate gyro: Heading source is a Rate of Turn gyro. 
"(calc.)" means the rate of turn is calculated from gyro 
movement. 

Initial setting of gyro1 is not necessary if it outputs 
serial data. However, if it is of synchro or stepper type, 
you will need to set initial gyro value. If gyro1 requires 
initial value, then the indication "(req. set)" is displayed. 
Use the scrollwheel to enter initial value. After you 
enter a value "req. set" disappears.
