End device
Your sensor, tracker or handset transmits directly to the satellite. Keys stay in a SEALSQ secure element.
Hardware root of trustTechnology
Secure by design, from chip to orbit.
WISeSat combines its own satellites, its own ground network and post-quantum security from SEALSQ into one end-to-end system. Here is how it works.
Sun-synchronousOrbit type
550–560 kmAltitude
≈ 97.4°Inclination
≈ 95 minOrbital period
Post-quantumEncryption
One message, five hops, no third party.
Follow a message from the device to your platform. Every link is protected by post-quantum encryption.
WISeSat satellite
Receives the message in low Earth orbit, processes it and relays it to the ground.
Sun-synchronous orbitGround station
Lausanne or La Línea collects the data and sends commands back to the fleet.
2 stations in EuropeMission control
Our Swiss operations center authenticates each message and checks its integrity.
Operated in SwitzerlandYour platform
Data reaches your systems through a secure API, ready to use.

Post-quantum security, layer by layer.
Hardware root of trust
Keys live in a SEALSQ secure element, out of reach of software attacks.
Post-quantum cryptography
Algorithms designed to resist attacks from future quantum computers.
Identity and PKI
Every device, satellite and station has a verifiable digital identity.
Continuous integrity
Any tampering along the path is detected and flagged.
