Trial Maneuvering In The Relative Vector Mode - JRC JMA-932B-SA User Manual

Trial Maneuvering in the Relative Vector Mode

The result of Trial maneuvering in the Relative Vector mode is shown by a change in target vector. In Fig.5-8
(in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired target is a
dangerous one because its vector is crossing the CPA RING.
The above figure shows that the relative vector of the target has changed as shown in Fig. 5-8 as a result of
simulation (course and speed), so that the symbol color is changed into "White", a safe target.
Irrespective of the simulation results, the current CPA and TCPA values are shown in the tracked target
information just like when the true vector mode is active.
The course change of own ship is displayed as a dotted-line.
Better information is provided by using relative motion and sea stabilization.
