Measurement Methods
Function
Used to measure the range and bearing from
the own ship's position.
Displays concentric circles having CCRP
(Consistent Common Reference Point) as the
centre at constant intervals in order to be used
as guidance for measuring the range.
Displays a straight line that specifies an
arbitrary bearing in order to measure the
bearing from own ship.
This equipment is equipped with two electronic
bearing lines (EBL1 and EBL2).
Displays a circle that specifies an arbitrary
range in order to measure the range from own
ship.
This equipment is equipped with two variable
range markers (VRM1 and VRM2).
Displays a group of straight lines at equal
intervals in order to be used for complex
measurement and guidance for route.
Displays a predictable track when own ship is
turned in order to be used as guidance for
manoeuvring.
Enables offsetting the own ship's position with
manual operation.
