Engineering Capability Without Unnecessary Complexity

DEFENSE • TEST • CONSULTANCY

Simetra provides specialist engineering expertise, software and consultancy solutions to Defence and commercial organisations, helping customers establish new technical capabilities and enhance existing ones.

Our approach combines first-principles engineering with transparent, accessible software that customers can understand, validate and adapt. Rather than relying on complex proprietary toolboxes, we develop solutions using widely supported programming languages and open-source development tools wherever practical.

From Sonar and Radar to Guidance, Navigation & Control, we help customers overcome technical barriers, strengthen their engineering teams and retain control of their technology.

With Simetra, you invest in engineering expertise and lasting capability, not unnecessary software licences, complexity or dependency.

Develop high-fidelity, first-principles models across Land, Maritime, Air and Space applications. Simetra delivers transparent, adaptable simulation solutions in your preferred programming language, helping you accelerate development, understand system behaviour and build lasting engineering capability.

Engineering Without the Black Box

At Simetra, we believe engineering software should be as understandable as the principles behind it.

Our sonar modelling and simulation tools demonstrate this approach in practice, bringing together physical scenario modelling, acoustic signal generation and sonar processing in transparent, observable engineering environments.

By making system behaviour and intermediate results accessible, we enable engineers to explore, understand and validate complex systems without unnecessary dependence on proprietary software toolboxes.

Explore our sonar simulation in action and see how first-principles engineering translates into practical capability.

About Our Founder

James Davies, Director of Simetra, is an engineer specializing in modeling, simulation, algorithms, and systems engineering within the defense sector. With a PhD from the University of Liverpool focused on target tracking and weapon guidance, James has built an extensive career developing solutions for land, sea, and air programs for organizations such as BAE Systems, Leonardo, and Thales. His expertise spans radar and sonar systems, sensor fusion, GNC, and Model Based Systems Engineering (MBSE), with a core focus on transforming complex engineering problems into robust, testable solutions using MATLAB, Python, and C++.
Established to provide high-quality modeling and simulation capability, Simetra reflects James's commitment to bridging the gap between specialist technical insight and practical application. His work addresses critical challenges in digital signal processing and navigation in GPS-denied environments while fostering innovation in test and evaluation. Beyond his consultancy work, James maintains strong ties to academia, collaborating with the University of Liverpool on research regarding quantum navigation and assured positioning. His goal remains centered on using the right combination of technology and engineering insight to improve system performance and mission confidence.
