6. MTU-AIS REPEATER FUNCTION.
The proAtoN application provides the ability to configure the MTUAIS repeater function.
Messages 21, 6, 8 and SART 1 and 14 can be repeated with a maximum of three hops.
The configuration of each message is done individually and can be selected which message types
are repeated.
All AIS messages include a “ Repeat Indicator ” indicating the number of hops made by the
message.
RI-0 are messages that have not been received directly from the source computer.
RI-1 Indicates message has been forwarded 1 time.
RI-2 Indicates message has been forwarded 2 times.
To avoid unnecessary hops and unnecessarily forwarded messages, you must choose the hop
scheme correctly based on the geography and distribution of AIS equipment.
There are 3 drop-down tabs where you can limit what type of messages will be forwarded.
The Save time will avoid forwarding two identical messages multiple times and preventing
uncontrolled message bounce.
The 21 Broadcast message can be limited in distance so as not to repeat messages that are at
an excessive distance and may not be interesting for navigators in the area where the forwarding
equipment is located.
