After an extended period of working with users to get their feedback, the UK Hydrographic Office (UKHO) has announced there will be significant changes to ADMIRALTY NavPac and Compact Data, which is part of the portfolio of ADMIRALTY Celestial Navigation and Astronomical products and services produced by our experts in Her Majesty's Nautical Almanac Office (HMNAO) team.
The new version of ADMIRALTY NavPac and Compact Data v4.1, has been released and is available to order from 28 May 2020 from the ADMIRALTY Miscellaneous Catalogue file. Users are advised to contact their ADMIRALTY Chart Agent for more details.
In response to user feedback, the new version of ADMIRALTY NavPac and Compact Data v4.1 is in a digital-only format, with extended data coverage for 2021 to 2025 and new product packaging. This represents a change from the previous paper book format of the product, to a CD containing the new v4.1 of the NavPac celestial navigation software, a digital version of ADMIRALTY NavPac and Compact Data eBook and product packaging comprising an environmentally friendly A4 size cardboard disc wallet.
The new v4.1 version is live and fully operational with immediate effect, including customer and technical support, upgrades and bug fixes from 28 May 2020 onwards.
Alongside the launch of ADMIRALTY NavPac and Compact Data v4.1, the previous versions – v3.4 and v4.0 - will be retired on 31 December 2020 in a phased sunsetting from market. Sunsetting is an intentional phasing out of a product or service designed to help users by providing a clear migration path and minimise any disruption.
What do users of NavPac and Compact Data need to do?
These changes will impact all existing users of ADMIRALTY NavPac and Compact Data.
This means that between 28 May 2020 and 31 December 2020 there will be three versions of ADMIRALTY NavPac and Compact Data live and in use:
NavPac and Compact Data DP330 v3.4 2016 – 2020
NavPac and Compact Data DP330 v4.0 2016 – 2020
NavPac and Compact Data DP330 v4.1 2021 – 2025
All current users will need to migrate to the new version of ADMIRALTY NavPac and Compact Data v4.1 by 31 December 2020. After this date, v3.4 and v4.0 go out of service and will no longer have functionality to enable users to do celestial navigation calculations for any dates from this point forwards and UKHO Customer Services and HMNAO technical support for these versions comes to an end.
From 28 May 2020 no further bug fixes or upgrades will be provided to v3.4 and 4.0, so the versions users are currently using will remain unchanged, and new users of these old versions will no longer be accepted into service.
ADMIRALTY NavPac and Compact Data users are advised to contact their Chart Agent to make arrangements to move to v4.1 in advance of the retirement date of v3.4 and v4.0 on 31 December 2020.
Tamsin Hodge, Product Manager, said:
"The new release of ADMIRALTY NavPac and Compact Data v4.1 represents an exciting development for users and navigation officers within the maritime industry. With this new digital-only version, users will have a greater range of data available to them to support celestial navigation at sea, as a verification for their on board Global Navigation Satellite System, with the same customer and technical support that they expect from all ADMIRALTY products. At the same time, we are here to help users and ADMIRALTY Chart Agents to plan for the retirement of previous versions of ADMIRALTY NavPac and Compact Data and a smooth transition to the new version."
What is ADMIRALTY NavPac and Compact Data and what is it used for?
ADMIRALTY NavPac and Compact Data provides navigators and astronomers with simple and efficient methods for calculating the position of the sun, moon, navigational planets and stars with the aid of a personal computer running Microsoft Windows 8 and 10.
It allows navigators to compute their position at sea using traditional celestial navigation techniques combined with modern technology.
ADMIRALTY NavPac and Compact Data is used world-wide by the Royal Navy and other navies around the world as well as commercial navigators who use it to provide independent and reliable verification to their on-board Global Navigation Satellite System (GNSS).
