Seren Station - Our First Ground Station

In 2022, our journey began with the inheritance of a weathered satellite dish—a relic from earlier missions that once heard the whispers of orbiting spacecraft. Though aged and limited in capability, this dish provided the crucial first foothold in ground communications. It taught us invaluable lessons in site calibration, signal optimisation, and the resilience required to run a ground station.

From this humble beginning, we centered our efforts on modernising infrastructure while honouring the legacy of those early transmissions. The old dish guided the design principles of subsequent installations, informing our choices in antenna mechanics, radio frequency shielding, and automated tracking systems.

Joining the SatNOGS Network in Q2 2026

In the first quarter of 2026, Infinity Groundstation will formally integrate with the SatNOGS open-source ground station network. This milestone extends our reach into a global, community-driven infrastructure, allowing us to schedule satellite passes, share real-time telemetry, and collaborate with operators around the world.

Participation in SatNOGS also accelerates our operational capabilities. We’ll gain access to a unified scheduling system, automated data pipelines, and crowdsourced maintenance support, all of which enhance uptime and data quality. This partnership embodies our mission to democratise space access—transforming Infinity Groundstation from a standalone asset into a node within a vibrant, decentralised network fueling innovation everywhere.

The Strategic Importance of Infinity Groundstation

Infinity Groundstation is a cornerstone of the UK’s sovereign satellite communications network, ensuring secure, uninterrupted control over mission‑critical data streams. By linking Low Earth Orbit assets directly, we eliminate reliance on foreign relay stations, reduce latency, and strengthen national security, operational resilience, and decision‑making speed.

In addition to its frontline operational role, Infinity Groundstation drives long‑term innovation and capability development. It provides defence agencies, research institutions, and strategic industry partners with direct access to live satellite telemetry, enabling advancements in remote sensing, secure Internet of Things connectivity, and space‑based intelligence.

Telemetry and Tracking Operations

Our advanced telemetry and tracking capabilities are powered by mission‑grade software, programmable radios, and rotator‑controlled antennas with full azimuth and elevation tracking. During satellite passes, the system autonomously acquires and locks onto target spacecraft, applies precise Doppler shift correction, demodulates telemetry, and, where authorised, executes secure command uplink operations. Processed data is relayed in near real‑time to defence mission control centres, government agencies, or strategic partners, ensuring rapid intelligence flow and operational responsiveness. Infinity Groundstation is a critical node in Infinity Space’s vision for a distributed, resilient, and sovereign UK space communications network. It directly supports our work in satellite development, propulsion innovation, and orbital experimentation, creating a secure, seamless link between assets in orbit and mission‑critical operations on the ground.
