Orbion Space Technology

Orbion Space Technology is a tier-one supplier specialising in electric propulsion systems for the small satellite market. The company focuses on the industrialisation of Hall-effect thruster technology, transitioning these complex plasma engines from bespoke scientific instruments to mass-produced hardware. By providing high-thrust-to-power ratios, their systems allow operators to perform orbital raising, station-keeping, and collision avoidance manoeuvres for spacecraft weighing between 50kg and 500kg. The organisation primarily serves commercial satellite constellation operators and government agencies, including the United States Space Force. Their flagship product is the Aurora propulsion system, a complete integrated solution including the thruster head, power processing unit, and propellant management system. They have secured numerous contracts to supply propulsion for Earth observation and secure communications platforms, positioning themselves as a critical link in the domestic space industrial base. Prospective buyers should confirm the specific integration requirements for their bus architecture, as electric propulsion demands significant peak power and thermal management. Partners should verify current production lead times for large-scale constellation orders and ensure compliance with International Traffic in Arms Regulations (ITAR) given the dual-use nature of the technology. Assessment of flight heritage on specific orbital regimes is recommended to validate long-term cathode reliability.
