Dominate the spectrum.
Own the mission.
Four Signal Labs builds an ultra-modular attachment for radio transceivers that fuses DoD-borne BLISS — Blind Interference Signal Suppression — with a compact receiver analyzer. Autonomous, robotic, and cyber hardware that self-orients against jamming and spoofing.
Wideband spectrum sensing pinpoints inbound guidance, remote control, Wi-Fi, and ambient RF in real time.
Onboard receiver analyzer computes signal-to-noise ratio and characterizes emitters at the edge.
Platforms self-orient and self-vector using signal-strength physics for maximal link quality.
BLISS suppresses adversary jamming and spoofing before it corrupts navigation or C2.
One module. Every platform.
From unmanned logistics to dismounted infantry, the FSL module clips into existing radio hardware and delivers signal awareness where it is decisive.
AIR & AUTONOMYDrone logistics under GNSS denial
Rotary and fixed-wing UAS retain positioning and control link fidelity when GPS is jammed, spoofed, or degraded — resolving true bearing from RF physics, not vulnerable satellite feeds.
GROUND FORCESWarfighter comms integrity
Dismounted teams stay networked. The receiver analyzer flags interference the operator cannot hear and BLISS protects the link from adversary EW payloads.
A receiver analyzer with a warfighter's edge.
Our unique bending of physics allows the FSL-01 to determine the specific strength-to-noise ratio of inbound guidance, remote control, Wi-Fi, and ambient RF — then self-orient the host platform for maximal transmission and receipt.
