ADP is a bundle of all ADMIRALTY Digital products supplied on a single CD. They include the equivalent of Volumes 2 and 6 of the Radio Signals, all volumes of List of Lights and all volumes of the ADMIRALTY Tide Tables.

Compared to the paper version, the ADMIRALTY Digital List of Lights is much easier to use and access information on the 70,000, or so, lights around the world. Similarly, Volume 6 of the ADMIRALTY Radio Signals provides maritime radio communications information for pilot services, vessel traffic services and port operations round the world, whilst Volume 2 provides compliant, digital positional and timekeeping references.

Updates to these publications are provided by CD or electronically using the weekly update service operated by Novaco either by email or satellite broadcast.
