It is just standard international weather code. The Russians use some of their Auxiliary vessels to act as weather ships. They can obviously deny it
if they want and simply cease transmitting. They normally do this when they go on exercise periods. Currently there is a Black Sea Fleet Tug on
exercise with the Italian Navy in the Mediterranean and it has ceased international weather during the exercise. Prior to the exercise it was sending
weather every six hours.
This is the standard international weather code. See following guide.
For example here is the weather from the Amur Class Floating Workshop PM-56 as it headed for Tartus, Syria on the 25th October. Depending on the
conditions I can normally pick it up here in the UK.
RCV DE RIR98 458 18 25 2200 458 = SML FOR RJE73 RJH45 =
25181 99346 10346 41598 63404 10230 40100 58013 70222 86420 22212 00190 20000 88000 25014 = + RIR98 K
If you go back to the link above you will be able to read the international weather and sea state codes. The interesting part is that the latitude and
longitude, course and speed are contained in the message.
Stripped out it reads 99346 10346 22212
This equates to 34.6N 34.6E Heading North East at 6-10 Knots
The auxiliary vessels are just sending regular international weather. If they require to go secure then they either fully encode Morse messages or
they set up a High Frequency data link by establishing the frequencies first by Morse Code.
See following guide.
If they want to go secure communications they follow the following format.
After establishing Morse call ups they send the frequencies to each other in the clear and then send encrypted data either in voice or teleprinter. Of
course they can also do this via a Morse message using their secure codes. Obviously unless you know the key then the messages are unreadable.
Currently the Russians are in the process of sending Task Forces to the Gulf of Aden/Horn of Africa for anti-piracy patrols.
The large Black Sea Fleet Tanker Ivan Bubnov has been sending International Weather on its passage from the Black Sea. As of midday it was hove to at
the following. It will probably transit the Suez Canal with the rest of the Black Sea Task Force?

This equates to
