Tracking | Argus Radar Operator Manual
ID code Displayed as a number from 1 to 40 for radar target tracks and from 1 to 200
for AIS tracks. For the radar tracked targets it is assigned by the system incre-
mentally, the last one plus 1 (if under 40), even if lower numbers are free. For
the AIS targets it is the lowest number available at the first reception. In both
cases the number remains with the target until it is cancelled. For AIS targets
there is also the possibility to display the Ship Names or the Call Sign next to
the ID Code (more details further ahead in this paragraph).
Vector
The direction indicates the target movements whilst the length indicates the
expected displacement of the target within an interval time (Vector Time).
If the target movement is slow, the vector length is a dot. It can be displayed
true or relative according to the vector presentation.
Past
Position The position where the targets have been in the past, plotted for every 30
seconds or every minute, or every 2 minutes… according to the choice in the
relevant field.
True vectors are selected by pressing the True/Relative Vector button (“True/Relative vector”
on page 101). The status is readable on the button after it has been pressed. This allows true
movement of targets, and is used to evaluate the actual traffic situation. Initially, after acquisi-
tion of a radar tracked target, the system will not have enough data to provide a reliable vec-
tor and only the initial state symbol will be displayed. After approximately 1 minute, the vector
will be drawn with the approximate speed and course, and after three minutes the symbol
will change and become steady, and the accurate vector will be visualised.
The true vector presentation is automatically disabled if the speed source is in failure or if
manual speed is selected.
Switching off the radar target symbols, all the above mentioned symbols related to radar tar-
get presentation will be removed from the screen, but the tracking will keep on computing.
The same for the AIS symbols.
Looking at the Graphic Symbols menu in previous page, the button down on the right
(“Display AIS Numbers”) is visualised only if the AIS is connected and switched on. Pressing it,
it is possible to select to have only the ID codes or also the Ship Name or the Call Sign (of the
selected AIS tracks) visible. Pressing the button, a list with the above choices will be displayed.

Note: Call sign and AIS names are displayed only for selected AIS targets. If the data is still not
available for an AIS, the MMSI is shown instead.
Route presentation and waypoint data
The system is able to display routes according to the sentences WPL and RTE. The below
example shows a route displayed in the PPI:
