Configure > AtoN message repeater (AtoN Station and Full Base Station)
To configure the AtoN message repeater, use the settings in the AtoN Message
Repeater category page.
The R60 can be set up to act as an Aids to Navigation (AtoN) repeater. In this mode the
R60 will listen to AtoN messages from specific MMSIs. When an AtoN message is
received from that particular MMSI the R60 will start repeating the same AtoN
message on the VHF-channels. Up to 30 AtoN message repeaters can be set up.
The AtoN repeater functionality has two main purposes:
-
Extend the range of AtoNs; since base stations normally has much better range
than AtoNs, primarily due to antenna height and output power.
-
Increase the report rate of AtoNs; since AtoN can be small devices with limited
available power (e.g. battery) their report rate can be limited.
The parameters on the page have the following meaning:
Group
Parameter Description

AtoN repeater number. All other settings on this page are related to the

Repeater
Check this box to enable/activate the repeater functionality for the
selected repeater number.
MMSI
The IALA MMSI number assigned to the AtoN.
Reporting
Rate
The interval in seconds between the transmitted reports for this AtoN.
Avoid settings this value too low, as it will increase the VDL load, but
use values below 360 (6 minutes) to avoid the target to be removed
from the target lists of the AIS users between transmissions.
Update
Timer
The update time in seconds. If no message is received from the AtoN
during this time period, the target will no longer be repeated.
If the value is 0, the AtoN information will continuously be sent out
with the period specified in the reporting interval, e.g. only one
reception from the AtoN is necessary to continuously repeat it.
