Passer Systems

Passer Systems is a Ukrainian-Estonian deeptech startup developing an ML-powered, camera-free navigation module for unmanned aerial vehicles. Our solution enables UAVs to maintain reliable positioning in GPS-denied environments — including situations where GPS is unavailable, unstable, jammed, or spoofed.

The product combines a compact hardware module with an ML-powered software layer. It processes inertial sensor data and flight dynamics to reduce navigation drift and improve positioning accuracy — without relying on cameras or external infrastructure. This makes the system effective in challenging environments such as defence operations, border monitoring, critical infrastructure protection, industrial inspections, indoor and underground operations, and search and rescue.
