Turning signals into intelligence

Two sister companies, one shared expertise: from applied research to intelligent systems deployed in the field.

Multiphysics MEMS sensingSignal processingIntelligent systemsEmbedded systems

Our model

A direct continuum from field to idea.

IAV Engineering explores, designs and validates solutions at the intersection of applied physics, electronics and software.

IAV Technologies turns this R&D into products, services and platforms built for sustained operation in the most demanding environments.

IAV Technologies SARL

Systems that scan, capture and intercept (…) then identify and understand.

Selected applications and projects

ARFANG-S2R®
High-infrasonic monitoring

Territorial infrasonic surveillance

Detect, recognise and locate infrasonic events.

A permanent array of four to eight sensors analyses infrasound coherence and direction of arrival, then classifies and locates avalanches, explosions, aircraft and other long-range events in near real time.

  • Goniometry
  • 4—8 sensors
  • AI classification
  • Cloud

Ad augusta, per angusta (‘Towards the heights by narrow paths’) — A pioneering culture

Independent by choice.
Exacting by nature.

A spin-off from EPFL's Electromagnetics and Acoustics Laboratory, IAV has cultivated a rare practice since 1997: staying close to the problem, working in symbiosis with partners and taking every system to its limits and through to proof.
