California-based Muon Space has unveiled its most capable satellite to date. The MuSat XL is a 500 kg-class satellite designed for the most demanding low Earth orbit (LEO) missions. Muon has also announced the first customer for the XL Platform. Hubble Network is a Seattle-based space-tech developer building the world’s first satellite-powered Bluetooth network.

The XL Platform delivers an expanded capability tier to the flight-proven Halo stack – delivering more power, agility, and integration flexibility while preserving the speed, scalability and cost-effectiveness needed for constellation deployment.

The XL Platform is optimised for Earth observation (EO) and telecommunications missions supporting commercial and national security customers that require multi-payload operations, extreme data throughput, high-performance intersatellite networking, and attitude control and pointing.

In 2024, Hubble became the first company to establish a Bluetooth connection directly to a satellite, fuelling global IoT growth. Using MuSat XL, it will deploy a next-generation BLE payload featuring a phased-array antenna and a receiver 20 times more powerful than its CubeSat predecessor, enabling BLE detection at 30 times lower power and direct connectivity for ultra-low-cost, energy-efficient devices worldwide. MuSat XL’s large payload accommodation, multi-kW power system, and cutting-edge networking and communications capabilities are key enablers for advanced services like Hubble’s.

“Muon’s platform gives us the scale and power to build a true Bluetooth layer around the Earth,” said Alex Haro, Co-Founder and CEO of Hubble Network.

The first two MuSat XL satellites will provide a 12-hour global revisit time, with a scalable design for faster coverage. Hubble’s BLE Network supports critical applications in logistics, infrastructure, defence, and consumer technology.

“XL is more than a bigger bus – it’s a true enabler for customers pushing the boundaries of what’s possible in orbit, like Hubble,” said Jonny Dyer, CEO of Muon Space. “Their transformative BLE technology represents the future of space-based services and we are ecstatic to enable their mission with the XL Platform and our Halo stack.”
