Modes of Reference Target
A Reference Target can be selected for Monitor mode, which means that Reference Target can be used for Gyro
correction and positioning of own ship. An other mode is for modifying Reference Target in Plan mode. In Plan
mode Reference Target is only displayed on ECDIS screen without using it for gyro correction or positioning of own
ship. Eventually the Monitored and Planned User Charts copy the operation of Monitored and Planned Routes.
Below is an example how to know which Reference Target is used Monitor mode and which one is in Plan mode.
Monitor mode Plan mode
A) A)
B)B)
On Upper Status bar the Ref Target field shows always the name of the Reference Target selected for Monitor mode.
If the displayed Reference Target on the ECDIS screen is the Monitored Reference Target, then the text "Ref
Target" on Upper Status bar is in black (See example "Monitor mode A"). If the displayed Reference Target on the
ECDIS screen is the Planned Reference Target, then the text "Ref Target" on Upper Status bar is in red (See
example "Plan mode A"). The name of the Planned Reference Target is only available in the window for Plan mode
of User Chart (See example "Plan mode B").
