Radio signal structure

These structures are used for localization (radionavigation), communication at sea (radiocommunication) and reception of information relating to navigation (navigation warnings) or meteorology (bulletins, notices, weather maps, etc.).

They give the characteristics of radio aids to navigation all over the world.

As part of the November 2021 streamlining, it was decided to reduce the coverage of 6 of the 10 existing radio signal structures to that of nautical charts. This concerns works 921 and 922 (maritime radio stations), 931 and 932 (port radiocommunications), 961 and 962 (maritime safety information). After reduction of the coverage, the works 921 and 922 are merged into a single work the "92", the 930 (non-port reporting systems) retains its current coverage (Western Europe, Channel, Western Mediterranean and overseas) is merged with 931 and 932 into a single structure, "93", structures 961 and 962 are also merged into a single structure, "96". Book 91 (maritime radionavigation) retains worldwide coverage for the part devoted to satellite positioning systems and terrestrial infrastructure radionavigation systems, but the chapters describing beacons (Racon, Ramarks, AIS) are also reduced to map coverage area. Book 924 (GMDSS) retains worldwide coverage. Book 99, which is a compilation of other radiosignal books, is deleted.
