Oxford Space Systems (OSS) was founded in 2013 and is headquartered in Harwell, Oxfordshire, United Kingdom. OSS aims to become the global leader in deployable antennas for space, delivering lightweight, cost-effective, and stowage-efficient solutions for satellite-based services. The company focuses on enabling next-generation spaceborne services, such as Earth observation, to address global challenges like weather monitoring, soil erosion, and illegal land use. OSS specializes in deployable antennas and structures for spacecraft, particularly for small satellites. It prioritizes innovative antenna designs and structures to enhance satellite performance, stowage efficiency, and cost-effectiveness.

OSS develops advanced deployable antennas and structures using proprietary materials and innovative design techniques, such as origami-inspired engineering. Key technologies include:

• Wrapped Rib Antenna: A 3m-diameter Cassegrain reflector antenna with a metal mesh surface, designed for high-frequency, high-resolution Synthetic Aperture Radar (SAR) missions. It stows compactly, making it ideal for small satellites.
• High-Strain Composite Materials: OSS has industrialized in-house knitting and composite processes, ensuring quality control and rapid iteration.
• Metal Mesh Reflector Surfaces: These enable high RF performance with minimal mass and complexity.

OSS and SSTL, supported by the UK Space Agency’s National Space Technology Programme, developed a deployable SAR antenna payload for small satellite missions. This collaboration resulted in the Wrapped Rib antenna integrated with SSTL’s CarbSAR platform. OSS collaborates with QuadSAT to use drone-based RF testing for large antennas.
