Targets

Note : the Target Center Window allows you to quickly sort the table using CPA or TCPA attributes.

IMPORTANT

It is a particularly powerful function for ensuring safety but, of course, considers that the two ships are traveling at constant speeds and headings.

CPA Warning

You can activate the Target CPA Warning under the "Option: Radar..." dialog box.

Security circle

You can draw around the boat position a security circle. As soon as a target is considered as a danger for the boat when the CPA distance is smaller than the security circle radius then its Icon changes (Red triangle) showing that it is closer to your boat.

To define the security circle :

1.Select [Option: GPS/Track... ] from the [Utilities] menu

2.First select a target in the list on which you want to apply settings.

3.Then select MISC tab to apply settings.

1.check "Display" to show it on chart.

2.enter a value in Size input text to define a circle distance.

Option: Monitoring Zone...

Users can create as many monitoring zone areas as they want. At first you must draw on the chart all areas you want to define as monitoring zones. Then save them in a specific PTF, this is important because you will have to call it for configuring Monitoring zone options.

Note that This option is only used for ARPA and AIS information incoming from system unit connected to MaxSea.

To set up Monitoring zone ...choose [Option: Monitoring zone ...] from [Targets] menu and a dialog box appears on screen and allows you to enter parameters according to your choice, this dialog box consists in three parts:

1 - Zone definition part

Press the Browse button.

Search and choose the PTF file which contains monitoring zone areas drawing.

2 - Events part

Choose a type of events :

1.Check Enter zone box , this allows alarm and the software will warn you each time a target mobile enters in a zone .

2.Check Escape zone box, this allows alarm and the software will warn you each time a target mobile leaves a zone.

3.Check Abnormal movement box, this allows alarm and the software will warn you each time target mobile, which was stopped in a zone, restarts moving. A target is considered as stopped when its SOG is under a limit value (SOG0). It restarts moving when its SOG is over a limit value (SOG1) or distance from stop point is greater than a limit value. Press the Advanced button for configuring "Abnormal movement parameters".

3 - Actions part

This part consists in how to choose the warning alarm type such as playing a sound and/or launching a program.

When an event occurs, you can:

1.Choose to play a sound by checking the Play sound box. Then click on the Browse button for searching and selecting an audio file ("wav" extension file format ).

2.Choose to launch a personal program by checking Run executable file box. Then click on the Browse button for searching and selecting your program ("bat" or "exe" extensions file format for example).

Notes:

1 - It is recommended to save the file in a specific folder on your PC, for after finding it easily.

2 - You can modify in real time your monitoring zones PTF file and it is simultaneously taking into account.

Click OK to validate. Your Monitoring zone is configured but not activated.

See next topic "Enable Monitoring Zone" for how to activate this function.

Enable Monitoring Zone

This function enables to activate configuring Monitoring zones which are defined in a chosen PTF file.

1.Choose [Enable Monitoring Zone] from the [Targets] menu for activating .

2.Click again on it to disable the Monitoring zone function.

3.A warning will appear if No zone to monitor is defined in the specified PTF file.

Targets Advanced Options

This dialog allows to control precisely recording observation of targets according to a situation.

By default each target average are determined and do not need to be modified. This feature allows to control your Mobile database optimization.

Some times, if you need to reduce the average interval of recorded frequency because there is too many targets in your

navigation zone area or if you would navigate for a long time in this zone area etc...

From MaxSea catalog:

1.Click Plus symbol nearest [Targets],

2.Click a chosen layer to pull down its menu

3.Click "Advanced Options..." to display the appropriate dialog.

This dialog enables for example modifying:

1.Average Track/Trail recording interval.

2.Average tracked mobile count.

3.Average track duration.

4.Average target received count.

5.Average trail duration.

A warning appears for wrong values and the changes are not applied.

Notes:

(1) - all the duration values are defined in second (time units) and the others are integer values. (2) - each default values are depending on a mobile type.

ARPA Targets

ARPA overview

When a target is selected on the radar, it is automatically displayed on the chart.

MaxSea will display the icons for all the targets tracked by the connected radar.

AIS Targets

AIS overview

- This function is included in MaxSea depending on your own software version. Before using it, the hardware installation has to be done.

MaxSea provides the capability to connect to an AIS and may provide remote presentation of reported AIS targets.

In combination with MaxSea, the AIS technology gives you an improved surveillance system and information about nearby ship traffic.

The three main components in the Transponder are :

•GPS-receiver,

•VHF-transceiver,

•Computer.

The GPS-receiver provides accurate position and navigation data, the computer packs this information together and broadcasts the data on a digital data link via the VHF-transceiver. All vessels within VHF range equipped with an AIS transponder can receive this message, unpack it, and plot the position, vessel name (references), speed over ground, course over ground of the other vessels..
