Organically monitors the radiated acoustic emissions of warships and submarines, aiding the localisation of noise sources.

Installed across the Royal Navy Fleet, this standalone system comprises transducer arrays, data acquisition and data distribution sub-systems and PC-based operator workstations. Alternatively, we can offer the transducers with network-based telemetry and embed the software application within existing sonar or combat system. The transducers comprise arrays of hull internally mounted accelerometers and external hydrophones, which can be populated throughout the platform or localised in particular compartments to provide real-time radiated noise estimates and to aid the localisation of noise sources. The software provides a modular acoustic analysis toolkit and an equipment database which allows the operators to customise the system to suit the platform configuration.

Current Developments

Rugged, high density, high dynamic range, low noise, low power data acquisition units, configurable for multiple sensor types, combined with dual redundant high speed network distribution of sensor and health data are about to go into service.

Active Intercept sonar

High-performance wideband processors that can be provided as complete hardware and/or software solutions using single arrays or multi-site architectures covering low to very high frequencies. We offer fully digital solutions, allowing easy integration within an integrated sonar suite by a third party.

Sonar Design & Integration

Developing, installing and testing components and algorithms across different sonar types and platforms. This includes upgrades and novel processing for submarine conformal arrays, development of inboard hardware to interface to legacy arrays, novel processing and error analysis for towed arrays, performance assessments of hull arrays, and solutions for unmanned vessels.

Research, Development & Trials

Highly capable sonar modelling and simulation capability, ideal for supporting algorithm development and system performance modelling using simulated or recorded data.

Complementary technologies for high-resilience position, frequency and timing systems for maritime platforms.

Navfix

Our naval GPS and distribution solution provides accurate location and timing through Standard Positioning Service (SPS) and encrypted Precise Positioning Service (PPS) to support robust navigational warfare capabilities. Navfix is currently in service on most Royal Navy submarines and surface ships (minesweeper and above).

Precise Time & Frequency Equipment (PTFE)

In the temporary absence of GPS satellite-received time, the PTFE will maintain precise time to an accuracy of less than 50µsec after 90 days (Caesium) or less than 250µsec after 45 days (Rubidium). Our Rubidium-based PTFE is currently in service with the Royal Navy as Outfit FSF and is fitted to some twenty-five operational ships, including Type 45 Destroyers. Our integrated Military GPS and PTFS (MGP) Systems including Navfix and a new variant of PTFE are being fitted to Type 26 and Type 31 platforms.

In-house System Engineering Experts

Developing and integrating equipment within an existing system or platform infrastructure, either to provide new functionality or overcome equipment obsolescence. This service includes the provision of a solution in a timely, effective manner, no matter where the customer is in the world.

In-Service Support

Including platform installation and setting to work, service and repair, contractor logistics support (CLS), post-design services, documentation, as well as environmental and safety management. This service is coupled with specialist facilities that allow our in-house technical experts to support sonar trials, static or underway calibration and sonar recording for data analysis.
