Fast and efficient upd​​ates

All ADRS applications allow 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.

Overlays to support voyage planning​

Easy to use and clearly displayed using a growing number of back-of-bridge software, including ADMIRALTY e-Navigator Planning Station, all ADRS applications can be viewed as a single layer on top of official navigational charts. By using this functionality, bridge crews can view relevant navigational information in one place, making it easier to plan voyages and view intended routes in detail.

Easy search and print ​​options​​

Crews can find radio signal information quickly using the map interface, the ship’s position or a keyword search. This information can then be easily printed​ for use in navigational activities such as passage planning.

Compliance with SOLAS and Flag States

All ADRS applications 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.
