Admiralty List of Radio Signals
The Admiralty List of Radio Signals series provides comprehensive information on all aspects of Maritime Radio Communications. The data is organised into six volumes, some divided into several parts for ease of handling. Each of the six volumes is presented in a user-friendly format with full colour photographs and diagrams.
The contents range from a complete listing of stations handling Maritime Public Correspondence to a full range of products and services essential for compliance with the GMDSS (Global Maritime Distress and Safety System). The volumes also feature radio stations broadcasting weather services and forecasts and a detailed explanation of the complexities of Global Satellite Position Fixing Systems. ALRS publications are presented in a user-friendly format and are updated through Section VI of the weekly editions of Admiralty Notices to Mariners. New Editions are published annually containing all changes to information held.

Admiralty List of Lights and Fog Signals
This series of books provides extensive information on all lighthouses, lightships, lit floating marks (over 8m in height), fog signals and other lights of navigational significance.
Each publication also gives the characteristics of lights and fog signals, together with the equivalent foreign language light descriptions. Tables can be used to calculate the geographical and luminous ranges of lights. Details for all lights listed include the international number, location and/or name, geographical co-ordinates, characteristics and intensity, elevation in metres, range in sea miles and description of structure.
We publish new editions of the Admiralty List of Lights and Fog Signals on a rolling cycle of revision. We also list important changes to lights in the weekly Admiralty Notices to Mariners.
