Oxford Space Systems, a leading innovator in deployable antennas for space, was successful with the on-orbit deployment of an S-band isoflux helical antenna for Astro Digital, a provider of satellite systems. The isoflux pattern enables wide and consistent coverage on the ground, enhancing satellite communication capabilities. This deployment builds on a strong collaboration between Oxford Space Systems and Astro Digital, supporting multiple satellites with advanced antenna solutions.
The S-band antenna was designed and manufactured by Oxford Space Systems to meet Astro Digital’s mission requirements. Its compact stowage and robust deployment mechanism ensure efficient use of spacecraft volume and mass, while delivering high-performance S-band communications for data transmission and ground coverage.

Sean Sutcliffe, CEO of Oxford Space Systems, commented, “The successful deployment and performance verification at high power of our S-band isoflux helical antenna for Astro Digital is a clear demonstration of our engineering expertise and commitment to mission success. We are proud to continue supporting Astro Digital with agile and reliable deployable antenna solutions.
Chris Biddy, CEO of Astro Digital, added, “We value our partnership with Oxford Space Systems and are pleased with the successful deployment of this S-band antenna. Their innovative approach to deployable antennas continues to support our mission needs and enables us to deliver reliable communications for our customers.”

Following deployment, the antenna underwent a transmit test, which confirmed its operational performance in orbit.
This deployment reinforces Oxford Space Systems’ position as a trusted partner in the global space industry, delivering high-performance deployable antennas for commercial and government missions.
