Network

One network, from orbit to your device.

WISeSat combines a constellation in low Earth orbit, its own ground stations and hardware-based post-quantum security into a single, sovereign network.

01 · Our satellites

From picosatellites to larger platforms.

We started small, proving our technology in orbit with picosatellites. Each generation, built with FOSSA Systems, brings more power and more room for secure connectivity.

02 · Ground network

Our own ground stations, in Europe.

Every pass of our satellites is tracked and commanded from stations we operate ourselves, with data delivered from Swiss mission control.
