RIDAR-FM
Every RID drone around you on the ATAK map in seconds: who's flying, where, where the pilot is standing, and whether it's real. Remote ID is the primary focus — RIDAR-FM also detects Bluetooth and WiFi emitters with passive direction finding. RX-only, air-gapped, in a lightweight carbon-fiber body.
Why RIDAR-FM
The first warning used to be the sound of rotors overhead — and by then, the drone had already seen you. RIDAR-FM hears it the moment it keys up: identifies the airframe, pins the ^pilot on the map^, verifies the signal is ^real^, and shares it with every screen on your team. All without transmitting ^a single watt^.

The detection chain
From first broadcast

Signal awareness
Not just drones.
Everything transmitting.
RIDAR-FM also surfaces the Bluetooth and WiFi emitters around you — phones, cameras, trackers, access points — and points you toward each one with passive direction finding. It only ever listens, so you never light up.
- BLE 4/5 and WiFi beacon + NaN, captured passively
- Direction finding toward every source on the map
- More operators, sharper fix — the team triangulates together
Rapid deploy
Operational in seconds.
Connect RIDAR-FM to the EUD and detections begin populating the map within seconds. No assembly, no calibration — operational as soon as it is connected over USB-C.
One sensor, three ways
Three ways
to run RIDAR.
The same detection engine — Remote ID, spoof analysis, IFF, and team CoT — wherever you work. Pick the surface that fits the mission.
Run RIDAR on its own device — a full tactical app with its own map, live detections, spoof analysis, and track history. No ATAK and no server required.
Push every detection straight onto the ATAK map as CoT — the pilot pinned, the airspace shared to your whole team over network, mesh, or radio.
Watch the airspace from a live web dashboard — built for the TOC or command post to monitor and review detections with nothing to install.
Choose your RIDAR
Two builds.
One detection core.
Both models run the identical detection software — Remote ID, spoof analysis, on-device intel, IFF, history, and team CoT. The hardware is the difference: rugged IP67 with ADS-B, or lightweight carbon fiber.

What do I need to run RIDAR-FM?+
RIDAR-FM is a complete sensor in a lightweight carbon-fiber housing — it plugs into an Android EUD running ATAK 5.2 or newer over USB-C (Bluetooth is also supported), powered from the EUD with no internal battery. The ATAK plugin is included; once connected, detections appear on your map within seconds. Each unit is hand-built to order in the USA and ships within 30–60 days, with all antennas and a waterproof USB-C cable in the box.
Does RIDAR-FM transmit or jam anything?+
No — RIDAR-FM only listens. It never transmits, jams, or interferes with anything, which keeps it quiet, undetectable, and legal to run in places where active counter-drone gear isn't allowed.
Which drones does it detect — and which does it not?+
Almost every commercial drone — DJI, Autel, Skydio, Parrot and the rest — broadcasts a Remote ID signal, and RIDAR-FM catches it. It does not track crewed aircraft (for that, choose the rugged RIDAR with ADS-B), and it can't see FPV or hand-built drones that don't broadcast Remote ID.
How does spoof detection work?+
RIDAR-FM scores every detection for authenticity, weighing multiple characteristics of the signal and its behavior into a single confidence level. Likely spoofed, replayed, or fabricated tracks are flagged with a clear AUTHENTIC or SPOOFED verdict on the detection card, and the scoring runs entirely on-device. We don't publish the specific factors the analyzer weighs — keeping them private is what keeps the scoring robust against spoofers who would try to game it.
Does it work offline?+
Yes — completely. Everything runs on the device itself, so RIDAR-FM works with no internet, no signal, and no cloud. Give it a connection and it adds extra detail when it can — but it never depends on one.
How does my team see the detections?+
Every detection is shared to your team's maps automatically — over your network, a mesh, or a radio. One operator's RIDAR-FM becomes the whole team's picture of the sky, with no setup on each device.
Does it cover the higher frequencies too?+
RIDAR-FM covers the main band where drones, Bluetooth, and WiFi broadcast, and works together with your device to extend into the higher band too — so you get the full picture with no extra gear.

The sky, accounted for. Silently.
Every Remote ID drone — identified, ranged, verified, and on every screen your team is watching. Plug it into the EUD already in your kit and the airspace becomes a live feed. It never transmits a thing.
