The ALRS is split across six volumes, some divided into several parts for ease of handling. Each volume contains detailed information on the radio stations, services, procedures and regulations relevant to its topic. The volumes are as follows:
Volume 1 (NP281) - Maritime Radio Stations (Parts 1 & 2)
Volume 2 (NP282) - Radio Aids to Navigation, Differential GPS (DGPS), Legal Time, Radio Time Signals and Electronic Position Fixing System (Parts 1 & 2)
Volume 3 (NP283) - Maritime Safety Information Services (Parts 1 & 2)
Volume 4 (NP284) - Meteorological Observation Stations
Volume 5 (NP285) - Global Maritime Distress and Safety System (GMDSS)
Volume 6 (NP286) - Pilot Services, Vessel Traffic Services and Port Operations (Parts 1 - 8)
The ALRS is also available as a digital publication within the Admiralty Digital Radio Signals (ADRS) range. The ADRS offers greater efficiency, faster updating and more flexible information access than the paper version. The ADRS is sold as three separate applications:
ADRS 1, 3, 4, 5 - Information to assist bridge crews in routine radio communications, receiving and providing weather reports and safety information, pollution and quarantine reporting, as well as seeking Telemedical Assistance Services (TMAS). This application also provides detailed procedures in the event of distress or SAR incident.
ADRS 2 - Positional and timekeeping references to aid the calculation of positions and times worldwide. Coverage includes worldwide listings of radar beacons, VHF radio-direction-finding stations, known AIS Aids to Navigation (AtoN), Radio beacons transmitting DGPS corrections, International radio time signal broadcast details and International standard and daylight saving times and dates.
ADRS 6 - Essential information for 3,800 service locations worldwide, including detailed pilot, Vessel Traffic Service (VTS) and port information with their respective contact details and procedures.
The ADRS allows users to find radio signal information quickly using the map interface, the shipâs position or a keyword search. The information can then be easily printed for use in navigational activities such as passage planning. The ADRS also allows users to download weekly electronic updates by Internet or disc. These can be applied accurately with minimum manual intervention; significantly reducing time spent making manual updates and minimising the risk of human error on board.
The ALRS and the ADRS are widely accepted as meeting SOLAS carriage requirements and are approved for use by the Flag States of over 80% of ships trading internationally; meaning ongoing safety and compliance for your ships, cargo and crew.
