What Cyrrus does

Cyrrus is a UK-based specialist aviation consultancy and technology vendor operating from Cyrrus House, Concept Business Court in Thirsk, North Yorkshire (registered as Cyrrus Limited in England and Wales, alongside a related entity Cyrrus Projects Limited). The firm serves airports, wind-energy developers, ANSPs, and aerospace operators across 14 countries in Europe, the Middle East and Asia, and reports having delivered services to more than 70 airports. Its offer is organized around four service lines: Airport Development (safety, runway optimisation, capacity studies, planning, aeronautical ground lighting, ANSP tenders); Airspace (IFP design and airspace change proposals, with a claimed 100% success rate in the UK and abroad); Safeguarding (obstacle, navigation, surveillance, lighting, wind-farm and glint/glare assessments); and Technology (CNS systems engineering, project management, requirements capture, procurement, test and commissioning, training).

The firm backs these services with a patented technology stack centred on radar data processing. Granted patents cover the Radar Video Signal Enhancer (RVSE), the AERIUM software suite (which integrates primary radar, secondary radar, ADS-B, and MLAT), and SMARTENER, a wind-farm radar mitigation product that exploits the statistical property that turbine blades are rarely seen simultaneously by multiple radars, plus a Mode S Interrogator Code Conflict Indicator. These run on Cyrrus's proprietary CUSP hardware platform — a compact 3HU rack unit handling both legacy serial and IP-based radar data, with format conversion (e.g., RDIF to ASTERIX). Patents and the CUSP platform differentiate the firm from purely advisory peers and create a hardware-and-software product revenue stream alongside services.

Cyrrus is monetised through professional services (quotation-based fees for CNS consultancy, IFP design, and project management; RPI-indexed on contract anniversaries; Standard Daily Rates for out-of-scope work) and through hardware/software product sales (CUSP, AERIUM, SMARTENER and related tooling, with 30-day payment terms). Pricing is not publicly disclosed. Go-to-market is direct enterprise field sales — phone and email-led — supported by a website with downloadable brochures, a LinkedIn presence, and a YouTube channel. Demand is generated primarily through industry reputation and repeat engagement (e.g., London Luton Airport since 2011), with named enterprise customers including Dublin, London Luton, Norwich, Birmingham, Athens, Ireland West, Airbus UK (Hawarden) and the Whitelake Consortium. Certifications held include ISO 9001:2015, ISO 14001:2015 (first-time award), SSIP Health & Safety, Cyber Essentials and PQS approval, supporting eligibility for safety- and government-procured aviation work.
