Where there's a signal,
there's a way.

GNSS-Denied Autonomy.

Turning ambient cellular signals of opportunity into unjammable navigation and silent airspace sensing for UAVs in contested environments.

Explore System
01 / ZERO EMISSION
100% Passive Stealth

Zero RF signature. Undetectable to adversarial radar-warning receivers and electronic surveillance.

02 / NON-COOPERATIVE
Signals of Opportunity

Operates with minimal degradation over uncooperative networks, achieving even higher performance when network data is available via cooperation or intelligence.

03 / MOSA ALIGNED
Universal Autopilot Bus

Native MAVLink, ROS 2, PX4, ArduPilot & ATAK — zero firmware rewrite.

04 / LOW SWaP-C
Tactical Fleet Scale

Engineered for Group 1–3 UAS and loitering munitions — minimal weight, full mission endurance.

Where We Operate

Built for contested airspace

One signal architecture, four mission-ready effects.

01 / DoD Tactical UAS

Navigate through jamming

GNSS-grade autonomy that holds when GNSS signals are spoofed, jammed, or simply absent.

Explore Atsmus Air
02 / DHS & Border Security

See what emits nothing

Passive radar tracks low-altitude drones off ambient signal — zero transmission, zero exposure.

Explore PDDR
03 / Bases & Infrastructure

Protect the perimeter

Continuous low-altitude coverage around airfields and critical infrastructure — no spectrum license required.

Explore Sentinel
04 / Visual Fallback

Complements vision based navigation

Maintains reliable drift-free positioning when optical and visual sensors fail in fog, smoke, dust, darkness, or adverse weather.
