01 · The network
We don't rent space. We own it.
Every link, from device to ground, is protected by post-quantum encryption. Our own satellites in low Earth orbit, operated from our own ground stations in Switzerland and Spain.

Own
Our constellation
Satellites dedicated to WISeSat services in low Earth orbit.
Connect
Direct to your device
Devices talk straight to our satellites. No tower, no third-party gateway.
Operate
From Switzerland
Mission control and our own ground stations.
Secure
Hardware-based encryption
Post-quantum encryption on every link.
02 · The technology
A full-stack operator, from chip to orbit to API.
Follow your data from the device to your platform. Every hop runs on infrastructure we operate, and every link is post-quantum encrypted.
01
End device
Sends encrypted data straight to orbit. Its identity lives in a SEALSQ secure element.
02
WISeSat satellite
Receives the signal in low Earth orbit, processes and relays it to the ground.
03
Ground station
Lausanne or La Línea collects the data and commands the fleet.
04
Mission control
Operated in Switzerland. Data is authenticated and checked for integrity.
05
Your platform
Delivered by API, ready for your teams and systems.

Security layer · every hop
Post-quantum, down to the chip.
Post-quantum cryptography embedded at chip level, in every device and satellite.
AuthenticationEvery device proves its identity via
PKI.
AuthorizationOnly approved parties access the data.
EncryptionQuantum-resistant, end to end.
IntegrityTampering is detectable at every step.
03 · Ground infrastructure
85% of the planet has no mobile signal. We cover it from orbit.

05 · Roadmap
From pilot missions to a sovereign constellation.
WISeSat is scaling toward a 100-satellite quantum-secure network, built with SEALSQ.
QSAT payload
Post-quantum cryptography key exchange from low Earth orbit.
QSOC service
99.9% uptime SLA for enterprise and government customers.
100 satellites
A sovereign, quantum-secure constellation.
Built for missions where the network can't fail.
Discuss your use case
Defence & security
Sovereign tactical links
Pilot programme with the Swiss Armed Forces since 2022 for secure LEO communications.
Off-grid messaging
Messaging beyond the last tower
Field teams, rangers and crews exchange secure messages device to device, relayed through orbit.
Emergency & SOS
A direct line when networks fail
Distress alerts and crisis coordination keep flowing when terrestrial networks are down or untrusted.
Remote asset tracking
Track and monitor anything, anywhere
One secure network for every remote asset, from containers at sea to sensors in the field.
