In the past, navigators have relied on the Admiralty Temporary and Preliminary Notices to Mariners (T&P NMs) to manually update their paper charts. Now, AIO is an integral element of its ECDIS-based navigation system making additional chart information available to ship’s navigators.
“With Northrop Grumman Sperry Marine’s AIO-compatible ECDIS, we enable our customers to plan and execute updated routes with increased safety and efficiency,” said Jeanne A Usher, managing director, Northrop Grumman Sperry Marine.
AIO is a free service included with the Admiralty Vector Chart Service (AVCS). The overlay contains worldwide T&P NMs to be used with ENCs. AIO is said to be the only service to include ENC Preliminary Notices to Mariners (EPNMs) – the result of the Admiralty Assurance Programme, a comprehensive review of the world’s Electronic Navigational Charts (ENCs) undertaken by the UK Hydrographic Office (UKHO) to identify and resolve significant differences between ENCs and existing paper charts.
Northrop Grumman is a global security company that provides systems, products and solutions in unmanned systems, cyber, C4ISR and logistics’ and modernisation.
