SEA to upgrade Royal Navy's ANPS
SEA will upgrade the Royal Navy's Ambient Noise Prediction System (ANPS) under a contract from the UK Ministry of Defence announced on 10 April.
The ANPS takes meteorological and oceanographic forecasts, together with oceanographic databases, and performs complex acoustic propagation calculations to produce regular forecasts of ambient noise conditions in the ocean. The results enable the naval vessels to plan operations and improve the effectiveness of their sonars, allowing them to adjust elements such as sonar frequencies and depths accordingly.
The upgrade will better equip the ANPS with the ability to manage changing noise sources in the marine environment, incorporating the latest available environmental information; and will take advantage of higher resolution meteorological models to produce ambient forecasts that will be used by vessels equipped with sonar assets throughout the UK Royal Navy.
The ANPS, used by the Royal Navy since 2003, was first developed by SEA, which worked in conjunction with the National Oceanography Centre in Southampton and in collaboration with NATO scientists to undertake research into acoustic characterisation of the seabed.
The ANPS is now part of the operational support provided to the fleet by the Joint Operational Meteorology and Oceanography Centre.
