Oxford Space Systems

What Oxford Space Systems does

Oxford Space Systems (OSS), founded in 2013 at the Harwell Science and Innovation Campus in Oxfordshire, is a UK-based space hardware company that designs and manufactures deployable antennas and structures for small satellites. Its product portfolio comprises five core antenna architectures — Helical, Yagi, Wrapped Rib, Offset Reflector, and Hinged Rib — supported by a proprietary in-house Ox-Mesh-WF knitted gold-plated tungsten wire reflector surface and carbon-fibre composite components. The Wrapped Rib and Offset Reflector target LEO synthetic aperture radar (SAR) missions; Helical and Yagi serve IoT/M2M and maritime AIS/VDES use cases; Hinged Rib addresses data relay and intersatellite links. Differentiated technology includes origami-inspired rib and helical deployment mechanisms, a patented self-synchronised offset reflector design, and an integrated composite manufacturing capability via facilities in Harwell and Abingdon (the latter opened in January 2023 with a new autoclave).

OSS operates a B2B enterprise sales model, supplying bespoke mission-critical antenna hardware directly to satellite manufacturers, integrators, and government defence buyers under multi-year contract programmes. Its go-to-market is anchored by named customers including SSTL (CarbSAR), Airbus Defence and Space (Oberon), Space Norway (MicroSAR), Lacuna Space (IoT constellation, 10 deployments), Startical (air traffic management), AAC Clyde Space, Astro Digital, Open Cosmos, OHB and FFI. Pricing is determined through direct commercial negotiation on a contract-by-contract basis with no public price list. The company monetises primarily via hardware sales for individual satellite missions and modestly recurring constellation contracts, with demand generated through industry conferences, trade delegations (DIT Export Champion), earned media, prime-contractor relationships, and UK/international government procurement channels.

The business is venture capital-backed with Longwall Ventures as lead investor since inception, alongside IQ Capital, Foresight WAE Technology, NSSIF, UK Innovation and Science Seed Fund, and several angel/EIS funds; reported cumulative disclosed raises approximate £15–20M. Management states revenue tripled over the two years to January 2024, headcount grew from 50 to over 100 engineers by September 2025, and the company holds ISO 9001:2015 certification under a CEO appointed in November 2019 (Sean Sutcliffe, Cambridge-trained engineer).

Core offering

Oxford Space Systems designs, manufactures, and supplies deployable antennas and supporting structures for small satellite platforms, including Helical, Yagi, Wrapped Rib, Offset Reflector, and Hinged Rib antenna architectures. The antennas are built using proprietary in-house materials such as knitted gold-plated tungsten metal mesh (Ox-Mesh-WF) and carbon-fibre composites, leveraging origami-inspired engineering to deliver lightweight, stowage-efficient, single-shot-deployable hardware for SAR, IoT, maritime tracking, and inter-satellite link missions. Products are sold directly to satellite primes, integrators, and government defence buyers.

Product overview

Oxford Space Systems is a venture capital-backed space technology company founded in 2013, specializing in deployable antennas for space applications. The company offers a portfolio of five core antenna products: HELICAL (scalable deployable helical for IoT/M2M communications), YAGI (VHF high-gain directional for maritime tracking), WRAPPED RIB (Cassegrain reflector for SAR applications), OFFSET REFLECTOR (large scalable reflector for SAR smallsats), and HINGED RIB (for smallsat constellations and intersatellite links). The product portfolio is supported by proprietary in-house manufactured Ox-Mesh-WF metal mesh reflector surfaces produced using innovative knitting technology. The company leverages kite-making skills and origami-inspired engineering techniques to develop antennas that are lighter, less complex, more stowage efficient, and more valuable than traditional alternatives, targeting the estimated £1.5bn global market for deployable antennas.
