ADMIRALTY Vector Chart Service

The world’s leading ENC service, helping crews to navigate safely and efficiently.

The ADMIRALTY Vector Chart Service (AVCS) is the most comprehensive, official, digital maritime chart service in the world; with over 18,000 Electronic Navigational Charts (ENCs) from hydrographic offices around the world, packaged and quality assured by the UKHO into a single value-added service. 

The most comprehensive global coverage available

AVCS provides the widest official coverage, allowing ships to navigate on ECDIS for the entirety of most major routes on a single chart service. This coverage includes 4,000 of the biggest and busiest ports worldwide, of which we offer unique coverage for over 150.

100% official, certification provided

All ENCs in AVCS satisfy the mandatory chart carriage requirements of SOLAS Chapter V, with certificates provided for local inspection.

All AVCS customers will also receive weekly ENC updates by internet download, email or disc. Installing the latest updates on a regular basis supports safe navigation and compliance with flag and port state requirements.

Operates on all ECDIS makes

AVCS is delivered in industry standard S-63 / S57 formats, guaranteeing compatibility with all ECDIS sold today – even in a mixed fleet.

AVCS S-63 Edition 1.1 also meets the latest mandated data protection standard from the International Hydrographic Organization (IHO), designed to reduce the risk of both data piracy and the distribution of unofficial, dangerous ENCs to the mariner.

Free unique ADMIRALTY Information Overlay feature

To help bridge crews identify areas of possible navigational uncertainty and risk at the crucial passage planning stage, all AVCS customers receive the unique ADMIRALTY Information Overlay (AIO) at no extra cost. Combining all UKHO Temporary and Preliminary Notices to Mariners (T&P NMs) for all ADMIRALTY Standard Nautical Charts, and ENC Preliminary Notice to Mariners (EP NMs), AIO is displayed as a single layer on top of an ENC.
