Trust is engineered.
Reliable systems begin with careful decisions, clear thinking and attention to the details.
Software architectures evaluated against specific engineering
requirements and measurable evidence.

Fallon Apus Orbital Systems is a British software and systems engineering company founded by Paul A. Fallon.
The company investigates difficult engineering problems across autonomous systems, engineering assurance, operational resilience and space systems.
Rather than defining itself around a single technology, Fallon Apus develops and evaluates software architectures against specific engineering requirements and measurable evidence.
Paul’s own route here was not a straight line: a Pioneer Soldier in the British Army who passed D and P Company and served two operational tours, a Butlin’s Red Coat, a qualified chef who flew and cooked for A-list guests, then a Humanities degree through the Open University and coding studies in Westminster, London.
ArcScript remains a proprietary research programme within this broader engineering mission.

Reliable systems begin with careful decisions, clear thinking and attention to the details.
We describe work by its actual status: research, prototype or validated result.
A future-focused mindset means staying curious, questioning assumptions and exploring beyond the familiar.
We are interested in conversations with engineering organisations working on autonomy, assurance, resilience and complex software systems.
