Vector Display At Posn1 - JRC JAN-701B Instruction Manual

3.27.2 Vector Display at POSN1

The COG vector (vector of the vessel's motion over the ground), HDG vector (vector of the vessel's
motion through the water) can be displayed for your ship's symbol.
The COG and HDG vectors can be displayed at lengths proportional to the ship's current speed in
minutes. For example, if the vector length is set as 10 minutes, the tip of the vector is the expected
position in 10 minutes assuming that the ship sails at the current speed.
