Introduction to Single and Multi-Target Tracking
The CyScan system can track either a single target or multiple targets:
Single-Target Tracking
During Single-Target Tracking, only one target is used.
Single-Target Tracking is quick and easy to use, but has the following limitations:
•
Tracking stability is affected if the target reflection is temporarily lost,
as there is no redundancy.
•
If the true target reflection is obscured by vessel operations,
there is a possibility that the sensor track could jump to another reflection.
•
Relative vessel heading cannot be calculated.
Multi-Target Tracking
In Multi-Target Mode, CyScan uses two or more targets. Guidance Marine recommends
using a minimum of three targets. Multi-target tracking has the following advantages
compared to single-target tracking:
•
Improved tracking stability.
•
Increased immunity to false reflections.
•
Redundancy allows tracking to continue even if a target is temporarily lost.
Redundancy is only provided when 3 or more targets are selected.
•
The vessel’s heading in relation to the Multi-Target Group can be calculated.
Note:
Multi-Target tracking assumes that all the reflectors are attached to the same rigid
body (e.g. rig). if the selected targets are not all mounted on the same structure it will
violate the rigid body assumption and tracking will be lost
To Start Tracking
For Single-Target Mode
1. Ensure that the dashboard is
In Command
mode.
2. Locate a reflection on the BEV, or in the Reflections tab located in the
Tracking Menu
.
3. Click on the required target reflection symbol. It changes to the selected state (diamond
shape with red dash around the outside and number “1” superimposed).
4. Click on the
Apply
button to confirm and begin tracking.
For Multi-Target Mode
1. Ensure that the dashboard is
In Command
.
2. Locate a reflection on the BEV, or in the Reflections tab located in the
Tracking Menu
.
3. Select a minimum of two target reflection symbols (see Selecting Targets for Multi-
Target Tracking on page 33). An ordinal number will be superimposed on each as they are
clicked. Reflections can be deselected by clicking on them again.
4. Click on the
Apply
button to confirm and begin tracking.
To Stop Tracking
Whilst tracking is in progress, a Stop button is embedded in the Tracking button on the
Side Bar.
1. Click on the
Stop
button.
2. Click on the
Apply
button to confirm.
