Run a private mesh,
or join the ring.

LAN Mode gives you a physically separated constellation. Cloud Mode adds the global fleet, TRing access and direct multi-cloud gateways.

Two satellites in orbit linked by a laser beam above the Earth.

The terminal we fly is the terminal we hardened on Earth

Same photonics stack, same production line as the 300 km of laser network already carrying 1.8 Tbps a day on rooftops and towers.

Where it goes

Deployments running today, on live commercial service.

Constellation backhaul

Route traffic in orbit instead of bouncing it off the ground at every hop.

Earth observation

Move high-volume imagery from orbit into processing without a teleport queue.

Sovereign and defence

A physically separated mesh that never touches shared infrastructure.

Research missions

Space-qualified for Europe’s first low-orbit 6G research laboratory.
