Allen Control Systems Announces FAFOS Long-Range Optical Drone Identification Solution
On October 29th, Allen Control Systems (ACS), a provider of autonomous precision robotics, officially introduced its Friend and Foe Operating System (FAFOS) for unmanned platforms. FAFOS is the first cryptographically secure, radio-silent identification friend-or-foe (IFF) solution specifically designed for the evolving landscape of drone warfare. This innovative system enables instantaneous, secure optical identification for drones and other platforms, eliminating dependence on vulnerable radio frequency (RF) signals in contested electromagnetic environments.
Utilizing modulated near-infrared (NIR) or short-wave infrared (SWIR) optical signals, FAFOS achieves authenticated identification in less than 200 milliseconds at distances of up to two kilometers. The operating process involves emitting a distinct optical pulse towards the target drone, which is equipped with onboard photodiodes. Upon receiving the signal, the drone verifies the cryptographic signature and responds with a secure optical flash, thereby confirming its identity through standard public-key cryptography. Additionally, FAFOS can securely transmit commands for friendly drones to land or return using the same optical communication channel.
Unlike traditional IFF systems that rely on RF signaling, often susceptible to jamming, spoofing, and detection within modern operational environments, FAFOS remains invisible to adversaries, resistant to interference, and functional in GPS- or communications-denied settings. Its low size, weight, and power consumption facilitate seamless integration across air, ground, and maritime platforms, making FAFOS a cost-effective, scalable solution for both military and commercial drone deconfliction requirements.
“As the military and commercial sectors face an influx of unmanned systems from both state and non-state actors, the need for reliable identification solutions has never been greater,” stated Mike Wior, co-founder and CEO of ACS. “Rapid and secure identification capabilities in signal-contested environments are critical to mitigating risks associated with IFF failures. FAFOS provides machine-speed authentication, preventing incidents such as friendly fire, unnecessary interceptor deployment, or unintended losses.”
ACS is dedicated to advancing the next generation of autonomous systems to address the complexities of contemporary warfare. The company’s flagship product, Bullfrog, is an autonomous precision weapon station that enhances the targeting accuracy of both legacy and modern firearms across diverse operational contexts. As drone threats become increasingly sophisticated, ACS remains committed to developing advanced technologies that address urgent needs for U.S. and allied forces.
