Section 6 Target Tracking and AIS
6-16
6.4.2.3 Vector length (Vector time)
The Vector Length of a target is proportional to its speed, and the vector time can be switched in a
range of 1 to 120 minutes.
The following figure shows an example in which the Vector Length is set to 6 min, and the tip of the
vector represents the target's position expected to reach 6 minutes later.
6.4.2.4 Setting the vector length
The Vector Length is set in min in the range from 1 min to 120 min.
1
Click on the Vector Length input box in the other ship information window.
2
Enter the Vector Length.
6.4.3 Setting collision decision criteria
Collision decision criteria are set based on CPA and TCPA.
For an outline of CPA and TCPA, refer to "6.2.3 Basic concept of collision avoidance."
Memo
Set the optimum values of collision decision conditions, with consideration for vessel type, water
area, weather and oceanographic conditions.
For the relations between those conditions and alarms, refer to "6.7 Alert Display".
