Mission

Unjammable links
for autonomous platforms.

Viastern was founded on a single conviction: RF is a liability. Laser is the answer.

Free space optical communication is unjammable, unlicensed, and orders of magnitude more bandwidth-dense than tactical radio. Drones, ground stations, and mobile platforms operating in contested environments need links that cannot be interfered with. Viastern is building the module that makes that possible — small enough to mount, fast enough to lock, and simple enough to integrate.

Foundation

One engineer. First principles.

The core PAT algorithm — Kalman filter, PID control, spiral search, dual-loop tracking — was designed, simulated, and ported to embedded C++ entirely from scratch. LCT-1 targets drone-to-ground links first. The roadmap extends to drone swarm mesh networks, mobile ground units, and beyond.

Roadmap
  • PAT algorithm designed & validated
  • C++ embedded library — all tests passing
  • LCT-1 hardware prototype
  • Field integration trials
  • Drone swarm mesh deployment
