for static and voyage data. When transmitting information over the Secure Link the
vessel is identified by a special Secure ID.
The Secure link can be used to relay received commercial AIS targets to other friendly
units operating on the same encrypted data link.
1.1.2
BFT Link
The BFT type link allows the R5 to send encrypted messages on the two standard AIS
channels using binary message 8. This link can be used in situations where a third
channel is not available, as required for operation of Secure Type data link.
Entire AIS messages will be encrypted and used as payload in standard AIS binary
messages, with a user defined DAC and FI code to identify encrypted message for
other BFT units.
Can be run in a compatible mode with STANAG 4668 ed.2 Annex C
1.1.3
STEDS Link
The STEDS encryption scheme enables the R5 to send encrypted messages on the
two standard AIS channels using binary message 25. This link can be used in
situations where a third channel is not available, as required for operation of a Secure
Type data link.
Can be run in a compatible mode with STANAG 4668 ed.2 Annex D

Bogus AIS and additional installation options
The Bogus AIS functions consist of a number of operator selectable features supporting
the special requirements of some qualified customers. This includes transmitting modified
AIS data publicly, while sending correct information to friendly units.
These functions are implemented in line with STANAG 4668 ed.1
1.2.1
Bogus AIS functions
Fast change of own ship information
, in order to quickly change the static and
voyage data transmitted by the R5 SUPREME transponder, up to 5 different
“bogus id:s” can be configured.
Support for bogus dynamic data
1
, it is possible to initiate transmission of non-
correct dynamic information based upon a pre-defined starting position, course
and speed. It is also possible to use externally generated bogus data, based upon
the flexible configuration of position sources, see below

.
Support for externally generated position reports
1
,
the R5 SUPREME W-AIS
supports transmission of externally composed messages which is input to the
system as VDM sentences. This allows an external system to create e.g. virtual
position reports for exercise purposes etc. to be sent as normal AIS reports.
External transmission switch
, the transmitter in the R5 SUPREME W-AIS
transponder can quickly be switched off by installing an external control switch to
one of the discrete interface signals on the R5 SUPREME transponder. If the
switch is activated, the R5 SUPREME transponder will be completely silent and all

The use of these features is solely at the discretion of the operator.
