    • Remotely monitors on-board chart and publication coverage, as well as licence permit status
    • Reduces shore-side administration
    Admiralty e-NAV
  • The back-of-bridge PC application that brings together a set of powerful voyage-planning tools to support safe and compliant navigation.

    These include an integrated ADMIRALTY digital catalogue, a chart and publication holdings management and updating service, and an enhanced viewer for ADMIRALTY digital products.

    Planning Station supports the voyage-planning process and frees up bridge crews to spend more time on other important duties.

    Quicker, more informed voyage-planning decisions
    Bridge crews can view relevant navigational information in one place, making it easier to plan voyages and view intended routes in detail.

    ADMIRALTY products that can be overlaid on AVCS and ARCS include:

    • ADMIRALTY TotalTide (ATT)
    • ADMIRALTY Digital List of Lights (ADLL)
    • ADMIRALTY Digital Radio Signals (ADRS)

    In addition, ADMIRALTY Information Overlay (AIO) can be displayed over AVCS.

    A comprehensive digital catalogue of ADMIRALTY products
    Bridge crews can access a catalogue of the most comprehensive range of SOLAS-compliant charts and publications available. This includes all the official digital and paper charts and reference publications that are available from the ADMIRALTY Nautical Products & Services portfolio.

    Your ADMIRALTY chart agent can include their own product catalogue too, enabling crew to create a single order for all the products they require.

    Easier navigational information management and ordering
    An essential part of the passage-planning process is to ensure the navigational information for an intended route is up-to-date and complete.

    With Planning Station, bridge officers can keep costs and download sizes under control by ordering only those charts and publications required for a specific voyage. With ADMIRALTY digital products and services, permits and data can be ordered and received immediately.

    Fast and efficient updates
    You can receive electronic updates for ADMIRALTY digital products by internet download, email or disc, and they can be applied quickly and accurately, with minimal human effort. In addition, it is easy to export information to the ECDIS.

    Planning Station also makes it easier to hand over incomplete passage-planning tasks between crew rotations.

    This digital updating service, available at no extra charge from the UKHO, reduces time and effort compared to paper-based products.

    Supporting inspections
    Planning Station lets bridge crews view when the ADMIRALTY digital products they carry were last updated (their status), and lets them print or export reports to support inspections.

    Extra navigational information displayed – ADMIRALTY Information Overlay (AIO)
    Helping bridge crews to identify areas of possible navigational uncertainty and risk, AVCS customers receive the unique AIO, at no extra cost. AIO displays all UKHO Temporary and Preliminary Notices to Mariners (T&P NMs) and ENC Preliminary Notices to Mariners (EP NMs) as a single layer on top of ENCs.

    Crews can view AIO using Planning Station, which is particularly valuable if the ECDIS on board does not currently display AIO.

    Updating your paper charts
    Bridge crews can seamlessly manage and update the paper charts and publications they hold by using paper chart updating applications that are authorised to work with Planning Station.

  • A web-based management tool for ADMIRALTY Nautical Products & Services, designed to reduce onshore administrative tasks, maintain cost control and help ensure carriage compliance at all times.

    Manage navigational compliance across your fleet
    Remotely monitor ADMIRALTY navigational charts and reference publications held on board, to check your ships have complete coverage for intended routes. This helps ensure your ships meet the carriage requirements of SOLAS Chapter V. You can also check when current digital products and services will expire.

    Closely manage costs of navigational products
    It is easy to order ADMIRALTY Nautical Products & Services, either by creating orders ashore or approving those received from your ships. To cut down further on administration, you can delegate approval entirely to your ADMIRALTY Chart Agent.

    Get permits when you want them
    You can access the navigational information held by each ship from a web-connected device, 24/7. And because your fleet operates 24/7, chart permits for ADMIRALTY digital products can be received by the ship almost immediately after an order is placed.

    Manage your ADMIRALTY products by geographical area
    To make life easier, you can use the geographical display in Fleet Manager to view and order charts and publications by area, position or intended route.

Admiralty Vector Chart Service (AVCS)

  • The ADMIRALTY Vector Chart Service (AVCS) is the most comprehensive, official, digital maritime chart service in the world; with over 13,000 Electronic Navigational Charts (ENCs) from hydrographic offices around the world, packaged and quality assured by the UKHO into a single value-added service

    AVCS helps your crews to navigate safely and efficiently, and helps to keep your ships compliant with flag and port state authorities.

    Capitalising on the UKHO’s expertise and position as a leading provider of nautical paper charts, AVCS also incorporates the unique ADMIRALTY Information Overlay (AIO), further helping to make passage planning simpler and safer.

    Admiralty AVCS
  • More routes, more ports
    AVCS provides the widest official coverage, allowing ships to navigate on ECDIS for the entirety of most major routes on a single chart service. Coverage includes the waters of Hong Kong, Taiwan, Thailand, Indonesia, United Arab Emirates, Vietnam and the Malacca Strait. AVCS also includes 2,950 of the biggest and busiest ports worldwide, of which we offer unique coverage for over 200.

    Carriage-compliant, 100% official ENCs
    All ships using AVCS on board receive a UKHO certificate. This certificate confirms that all ENCs in AVCS satisfy the chart carriage requirements of SOLAS Chapter V , and can be used for local inspection.

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

    Available on one DVD
    AVCS is now available on one DVD, so users should experience faster loading speeds, fewer warning messages and reduced data handling.

    Optimised chart holdings
    For maximum convenience AVCS ENCs can be ordered in predefined transit, regional or port folios (groupings of ENCs). New ENCs are automatically added to folio holdings as soon as they become available, ensuring ships always have the latest data within their chosen level of coverage.

    Alternatively, all ENCs within AVCS can be bought on an individual, chart-by-chart basis for precise coverage and voyage flexibility. Simply buy the licences to unlock the charts needed for a voyage – when and for as long (3, 6, 9 or 12 months) as they are needed.

    Easy chart selection, ordering and management
    ADMIRALTY e-Navigator Planning Station is a chart selection, ordering and management software tool. Depending on the ship communications systems, it can help bridge crews receive updates and new data at sea via the internet, so you can be sure that they are always operating on the most up to date information.

    Where chart permits allow, Planning Station also lets your crews view both ENCs and the unique ADMIRALTY Information Overlay to identify the safest and most efficient route for their voyage. They can also use it to order any additional navigational charts, reference books and guides they need to carry out their voyage.

  • S-63 is the IHO standard for the protection of ENC information. The IHO has announced that, from 1 January 2014, Edition 1.1 is the active version of the standard.

    The ADMIRALTY Vector Chart Service (AVCS) and ADMIRALTY ECDIS Service are delivered in S-63 1.1 format on CD, DVD and via the Internet.

    To determine if their ECDIS is compatible with S-63 Edition 1.1, users should first check the type-approval date of their equipment. All ECDIS type-approved after 1 January 2009 are compatible.

    Many other ECDIS can also use S-63 Edition 1.1 data providing they have the functionality to change the certificate file (Public Key) that is being used.

    The following table shows the compatibility information reported to UKHO by ECDIS manufacturers. Where possible, UKHO has created install guides in PDF and/or films to help demonstrate the procedures needed to upgrade your ECDIS to use the new AVCS S-63 1.1 DVD.
