SoarAqua® (ZEN OS & ORAC)

A hardware-agnostic Edge AI platform under development for coordinated aerial and underwater operations. Designed to combine aerial LiDAR, subsea multibeam and imaging sonar data into a shared, georeferenced 3D model, with accuracy assessed through validation.

  • Design objectives: STANAG 4586 interoperability, GNSS anti-spoofing safeguards and a zero-trust audit architecture; validation pending
  • Rigorous geodetic transformation engine: ETRS89/BGS2005, EVRS, UTM, and US grids (GEOID18 / NAVD88)
  • ORAC Edge AI: Neural network defect recognition for underwater pipelines, power cables, and dam walls
