Purpose-built for high orbits.

Our satellites are small, radiation-tolerant, and low-cost. That combination was
considered impossible — until we launched the world’s first MicroGEO satellite.

Space-tested, space-validated.

We launched our first MicroGEO satellite in 2023 — Arcturus. It’s now executing communications missions for government and commercial customers around the world, and all of the Astranis-designed hardware on board is working perfectly on orbit.

On-board propulsion

We have already relocated Arcturus multiple times, and are fueled for many more years of continued operation.

Software-defined radio

Our proprietary SDR allows us to reallocate bandwidth and power on the fly, across 7 GHz of simultaneous bandwidth.

Radiation-tolerant electronics

Astranis-designed hardware has already weathered multiple solar storms in space, without issue.

Four upgraded satellites, launching soon.

We ship upgraded hardware (and software) every single year. For our 2024 launch of four MicroGEO Prime satellites, we added a larger main reflector, a gimbal for our electric-propulsion thruster, and added redundancy across the system, most notably to our software-defined radio.

And we’re already looking ahead to what’s next.

We’re scaling up MicroGEO production, fast. Our current facility in San Francisco can grow to output 24 satellites per year, which will mean we After Prime is Omega — a satellite more powerful, pound-for-pound, than any other system on orbit today.
