At Callen-Lenz, our high integrity software team specialises in the design, development, and verification of safety-critical flight software for crewed and uncrewed aircraft. We combine advanced engineering methods with rigorous certification standards to deliver reliable, high-performance control systems that can be trusted in mission-critical environments.
Our team works across the full lifecycle, from concept analysis and system requirements, through model-based design and auto-code generation, to software-in-loop (SIL) and hardware-in-loop (HIL) testing. This integrated approach ensures that every line of code is traceable, testable, and ready for certification under recognised aerospace standards such as DO-178C, DO-254, ARP4754, and ARP4761.
Supported by in-house simulation and verification tools, the high integrity software team develops flight control, mission management, and avionics software that underpins our next-generation aircraft systems. Their expertise enables faster development cycles without compromising on safety, ensuring our products meet the highest standards of performance, reliability and airworthiness.
Our technical capabilities ensure safety, reliability and operational excellence at every stage of development.
Concept Analysis
Our expertise in concept analysis for aircraft design and system requirements capture is a unique combination. Leveraging our array of proprietary tools and advanced analysis techniques, we excel in evaluating mission objectives, performance considerations, and aerodynamics. Our capabilities enable us to provide comprehensive support in optimising aircraft concepts, ensuring the development of robust designs that meet the highest standards of excellence.
Modelling and simulation
We specialise in developing reliable flight dynamics models to drive design, control software development, simulation, and training. Our robust modelling techniques allow us to rapidly generate mid-fidelity models, expediting control software development for rapid prototyping. Additionally, our high-fidelity models support qualifiable controller development. With streamlined aero-propulsive analysis techniques, our agility in aircraft modelling sets us apart, allowing us to deliver relevant solutions for the aerospace industry.
Flight control software development
Our model-based software development approach enables us to deliver qualifiable control software. By leveraging auto-code generation, we minimise coding errors, enhance testing procedures, and allocate more time for refining controller design. Our expertise in model-based techniques enables efficient deployment of advanced features and techniques, reducing development efforts.

Koios
Products
Our multi-disciplinary teams provide OEM avionics system design, payload integration, and support across the aerospace domain, including autopilots, flight control systems, platform management computers, and ground control stations. This capability enables us to rapidly adopt new technologies while remaining cyber secure.
Technical services
We have extensive knowledge and credible experience across crewed and uncrewed aircraft design, development, manufacture, production, delivery, test and evaluation and regulatory compliance. We offer our customers unbiased advice and support to optimise programmes, reduce risk and deliver pioneering technical solutions.
Platform development
Operational services
We have a history of delivering reliable, repeatable, international UAS operations since 2008. The rapid evolution of UAS capabilities and integrations is often best exploited as a ‘capability as a service’. To help clients achieve mission success, we offer planning, commissioning and execution of operational services in challenging environments globally.
