6.15 Configure > Aids to navigation (AtoN Station and Full Base Station)
Settings for aids to navigation are found by selecting the Configure base category and
then select the Aids to Navigation sub-category.
The R60 unit is compatible to Type 3 Aids to Navigation (AtoN) as defined in Ref [6]
and Ref [10]. It can be set up to transmit AtoN data by means of VDL message number
21 as defined in Ref [2]. By doing this, the AIS users can receive information about the
AtoNs even if the AtoNs themselves are not equipped with any AIS VDL transmitter.
The AIS users will not know the difference, so this is sometimes referred to as virtual
AIS targets. As many as 30 virtual/synthetic AtoN targets can be generated by the R60.
The parameters have the following meaning:
Group
Parameter
Description
-
1-30
AtoN target definition number. All other settings on this page are
related to the selected target definition number.
General
Active
Check this box in order to enable transmission of the displayed AtoN
data.
MMSI
The IALA MMSI number assigned to the AtoN.
Name
The name of the AtoN.
Type
The AtoN type. There are 32 available types, which appear in a drop-
down list.
More information about AtoN types is found in Ref [6].
EPFS
Type of electronic position fixing device for the AtoN position. Default is
surveyed.
Timestamp
UTC second when the report was generated (0 - 59).
60 if the time stamp is not available, which is also the default value.
61 if the positioning system is in manual input mode.
62 if the Electronic Position Fixing System operates in estimated
(dead reckoning) mode.
63 if the positioning system is inoperative.
Update
Timer
The update time in seconds. If the AtoN target is not updated via
Ethernet during this time period, the target will be deactivated.
If the value is 0 then no updates are necessary. The target will
continuously be sent with a period specified in the reporting interval.
Position
Latitude
Longitude
The latitude and longitude of the AtoN position.
The coordinates format is:
degrees
N/S/E/W
minutes
.
fractions of minutes
Example: Latitude = 16N12.9823, meaning 16° North and 12.9823'
Transmit
Schedule
The R60 can use two different methods to select transmit slots for AtoNs:
 RATDMA: In this case the base station needs to have RATDMA enabled to
allow it to find appropriate transmit slots, see section 6.3.
 FATDMA: In this case the slots selected for transmission should be allocated
using Remote ownership in Data Link Management, see section 6.8.
