1. About this volume

Drone RemoteID detection is one of the two capabilities nothing else in tjscientist’s lineup covers (the other is hidden-camera detection, Vol 7). This volume is the engineer-grade reference for it: what RemoteID actually is, the broadcast standard underneath it, how the nyanBOX picks it up, and — critically — the honest boundaries of what a small handheld can and can’t see.

RemoteID is sometimes oversold as “drone radar”. It is not. It’s a cooperative-broadcast detection system: it sees drones that choose to comply by broadcasting their ID. This volume is careful about that line throughout.


2. What RemoteID is — the regulatory backdrop

Remote Identification (RemoteID) is a regulatory requirement that most drones broadcast identifying information while flying — informally, “a digital license plate for drones.”

2.1 The rules

JurisdictionRuleStatus
United StatesFAA 14 CFR Part 89 — Remote Identification of Unmanned AircraftIn force; compliance required for most drones operated in US airspace
European UnionEASA — Direct Remote Identification under EU 2019/945 + 2019/947In force; required for most classes
Other jurisdictionsVarious — many following the FAA/EASA patternPatchwork; expanding

2.2 What a compliant drone broadcasts

A RemoteID-compliant drone, while airborne, periodically broadcasts:

  • Drone ID — a unique identifier (serial number or session ID)
  • Drone position — latitude, longitude, altitude
  • Drone velocity — speed + direction
  • Operator/control-station position — where the pilot is (this is the privacy-sensitive part)
  • Emergency status — if the drone is in an emergency state
  • Timestamp

2.3 Two ways to comply

MethodWhat it isDetectable by nyanBOX?
Standard RemoteIDThe drone broadcasts directly from the aircraftYes — this is what the nyanBOX detects
Broadcast ModuleA separate add-on module broadcasts on behalf of a non-RID-native droneYes — same broadcast transports
(Network RemoteID — proposed/varies)Reporting via internet rather than RF broadcastNo — there’s no RF to detect

The nyanBOX detects the RF broadcast forms. It cannot detect a drone that complies purely via a network/internet method (where one exists), and it cannot detect a drone that isn’t broadcasting at all (non-compliant, or RemoteID disabled — see § 7).


3. ASTM F3411 — the broadcast standard

The technical standard underneath RemoteID is ASTM F3411 (“Standard Specification for Remote ID and Tracking”). The FAA’s Part 89 and EASA’s requirements both reference it. F3411 defines:

  • The message format — the structure of the broadcast data (§ 5)
  • The broadcast transports — Wi-Fi and Bluetooth methods (§ 4)
  • The broadcast rate — typically ~1 Hz (once per second) minimum while airborne
  • The data fields — exactly what’s in each message type
   RemoteID — the layer cake

   └─────────────────────────────────────────┘

   The nyanBOX operates at the bottom layer — it listens
   to the RF transports and decodes the F3411 message
   format. It doesn't "know about" the law; it knows
   about the packets.

The key engineering fact: RemoteID rides on ordinary Wi-Fi and Bluetooth transports. It’s not a new radio. That’s exactly why an ESP32 (which has Wi-Fi + BT) can detect it — and exactly why a generic Wi-Fi scanner sees the frames but doesn’t decode them as RemoteID unless it’s specifically built to (the nyanBOX is).


4. The four broadcast transports

ASTM F3411 defines (broadly) four ways the broadcast can be carried. All four are 2.4 GHz (and 5 GHz for some Wi-Fi modes, but the common case is 2.4 GHz):

TransportCarrierHow it worksnyanBOX detects?
Wi-Fi Beacon802.11 beacon framesRemoteID data is embedded in vendor-specific information elements in beacon framesYes — ESP32 monitor mode
Wi-Fi NANWi-Fi Neighbor Awareness NetworkingRemoteID data in NAN service-discovery framesYes — ESP32 monitor mode (NAN is 2.4 GHz)

   Wi-Fi beacon:    └─ ch1 ─────┴─ ch6 ─────┴─ ch11 (+ others)
   Wi-Fi NAN:       mostly ch6 (2437) — the NAN "social channel"

   A drone might use ANY of these. A complete RemoteID
   watch needs to monitor Wi-Fi beacons across channels
   AND BT advertising across ch37/38/39 — concurrently.
   That's why the ESP32's dual Wi-Fi+BT radio matters.

4.1 Why the ESP32-WROOM-32U is the right radio for this

RemoteID detection needs Wi-Fi monitor mode AND Bluetooth advertising scan, ideally concurrent. The ESP32 (original, in the nyanBOX) has:

  • Wi-Fi 2.4 GHz with monitor mode → catches Wi-Fi Beacon + NAN RemoteID
  • Bluetooth 5.0 (BLE + Classic) → catches BT4 Legacy + (partially) BT5 Long Range RemoteID

It is, almost by accident, a near-ideal RemoteID-detection radio. The firmware time-slices Wi-Fi and BT (the single ESP32 radio can’t truly do both at the same instant), but the slice is fast enough to catch the ~1 Hz RemoteID broadcast rate.


5. The RemoteID message set

ASTM F3411 defines several message types. The ones that matter for detection:

Message typeContentsWhy it matters
Basic IDThe drone’s unique ID (serial or session ID) + UA typeIdentifies which drone
Location/VectorDrone lat/lon/alt, speed, heading, vertical rateWhere the drone is + where it’s going
AuthenticationCryptographic auth data (optional)Verifies the broadcast is genuine
Self-IDFree-text description / operation intentOperator-supplied context
SystemOperator/control-station lat/lon, area of operationWhere the pilot is — privacy-sensitive
Operator IDOperator registration IDWho the operator is (registered)
   A RemoteID broadcast — what you actually receive

   ├─ Operator ID ───────────────────────────────────┤
   │ Operator ID: FA3ABC123XYZ  (example)            │
   └─────────────────────────────────────────────────┘

   The nyanBOX OLED can't show all of this at once —
   it shows the highlights (ID, drone position, operator
   bearing) and lets you scroll. The full message set is
   in RAM; pull it over USB-serial (Vol 9) for the
   complete record.

5.1 The operator-position field is the consequential one

Most of RemoteID is “there’s a drone over there.” The System message’s operator position is different — it tells you where the human pilot is standing. For situational awareness / counter-surveillance, that’s the high-value field: if a drone is watching a site, RemoteID can tell you where the person controlling it is.

This is also the privacy-debated part of RemoteID — the rule deliberately exposes the operator’s location, and that’s controversial. The nyanBOX just decodes what’s broadcast; the ethics of acting on operator position is Vol 11 § 5 and § 9 below.

6.2 What the nyanBOX adds over a generic scanner

A generic Wi-Fi/BT scanner sees the frames. The nyanBOX:

  1. Knows the RemoteID frame signatures — the specific IEs, service UUIDs, AD structures
  2. Decodes the F3411 message format — turns raw bytes into “drone ID, position, operator location”
  3. Presents it as a drone watch — a purpose-built UI, not a raw frame dump

That decode-and-present layer is the entire value. It’s not new radio hardware; it’s the firmware knowing what RemoteID looks like.

6.3 RSSI as a proximity cue

The nyanBOX shows RSSI per detected drone. RSSI isn’t range (multipath, antenna orientation, drone TX power all corrupt it) — but RSSI trend is useful: a drone whose RSSI is rising is getting closer. Combined with the triple-NRF24 triangulation principle (Vol 3 § 8 — though RemoteID detection uses the ESP32 radio, not the NRF24s), you get a rough “warmer/colder” sense.

7. What is and isn’t detectable

This is the honest-boundaries section. RemoteID detection is real and useful, but it is cooperative-broadcast detection, and the limits matter.

7.1 What the nyanBOX WILL detect

DetectableWhy
RemoteID-compliant drones broadcasting nearbyThey’re broadcasting on Wi-Fi/BT exactly to be detected
Drones with a Broadcast Module add-onSame transports
The drone’s ID, position, velocityIt’s in the broadcast
The operator/pilot positionIt’s in the System message
Multiple drones at onceThe firmware lists all it hears

7.2 What the nyanBOX will NOT detect

Not detectableWhy
Non-compliant dronesIf a drone isn’t broadcasting RemoteID at all, there’s no RF to hear. Older drones, DIY drones, deliberately-non-compliant drones — invisible.
Drones with RemoteID disabled / spoofedRemoteID is enforced by regulation, not by physics. A drone that’s been modified to not broadcast (illegal, but possible) is invisible.
Network-RemoteID-only dronesIf a jurisdiction allows internet-based reporting instead of RF broadcast, there’s no RF.
Drones beyond RF rangeRemoteID broadcasts are low-power; a drone high up or far away may be below detection threshold. You detect cooperative and close, not regional surveillance.
Whether the broadcast is truthfulPosition fields can be spoofed by a determined adversary. The Authentication message helps, but it’s optional and not always present.

7.3 The BT5 Long Range partial-detection caveat

The original ESP32 (in the nyanBOX) has Bluetooth 5.0, but its support for BT5 extended advertising on the coded PHY (the “Long Range” mode) is limited compared to newer silicon (ESP32-C3/S3/C6). RemoteID broadcasts that use BT5 Long Range coded PHY may be partially or not detected by the nyanBOX. Wi-Fi Beacon, Wi-Fi NAN, and BT4 Legacy RemoteID are solidly detectable; BT5 Long Range is the soft spot. Verify the firmware’s actual BT5 coverage on the unit.

7.4 The honest summary

   What RemoteID detection IS and ISN'T
   ══════════════════════════════════════

   IS:   "Is there a compliant drone broadcasting near me
          right now, and if so, what's its ID and where's
          the operator?"

   ISN'T: "Is there ANY drone anywhere near me?"
          (non-compliant drones are invisible)

   ISN'T: "Drone radar / regional airspace surveillance"
          (it's near-field, cooperative-broadcast only)

   ISN'T: "Provably truthful drone tracking"
          (position fields can be spoofed)

   It's a genuinely useful situational-awareness tool
   within those boundaries. Sold as more than that, it's
   overhyped. The nyanBOX deep dive states the boundary
   plainly so the capability is used for what it is.

8. The RemoteID-watch workflow

8.1 Stationary watch

1. Position the nyanBOX (antenna clear, ideally elevated)
2. Enter Drone RemoteID mode
3. The firmware time-slices Wi-Fi + BT, watching for
   RemoteID broadcasts
4. Detected drones appear in a list — ID, RSSI, position
5. Select a drone → detail view: full position, velocity,
   operator location, operator ID
6. Watch RSSI trend to sense approach/departure
7. (For a record: pull the RAM log over USB-serial —
   the EEPROM can't store a long watch; Vol 9 § 4)

Battery: ~13.5 hours on the 2500 mAh cell (Vol 2 § 5.4) — a genuine all-day stationary watch.

8.2 Mobile sweep

Walk a site with RemoteID mode running — useful for “is anything watching this area” sweeps. RSSI trend as you move gives a rough bearing toward any detected drone.

8.3 Cross-referencing detections

A detected drone’s ID can be cross-referenced:

  • Serial-number IDs → in some jurisdictions, against a registration database (the FAA’s, where accessible)
  • Operator ID → against operator-registration records
  • Position history → logged over time, shows the drone’s flight path

The nyanBOX gives you the detection; the cross-referencing is host-side work with the data you pulled off the device.

8.4 What the workflow is good for

Use caseFit
”Is a drone surveilling this site?”Good — for compliant drones
Privacy / counter-surveillance auditGood — within the cooperative-detection limit
Situational awareness at an event/siteGood
Airspace enforcement / regulatoryPartial — you see compliant drones, not violators
Comprehensive drone defenseNo — non-compliant drones are the threat, and those are invisible

RemoteID broadcasts are intentionally public — the entire regulatory point is that anyone can receive them. Detecting and decoding RemoteID is legal; it’s a designed-in capability. The nyanBOX’s RemoteID tool is passive RX — no transmission, no legal RF concern.

9.2 The ethical line is what you DO with it

The data includes the operator’s location. That’s a real person standing somewhere. Detecting that a drone’s pilot is at a given location is legal; what’s done next is an ethics question:

UsePosture
Situational awareness — “there’s a drone, operator’s that way”Fine
Privacy audit — “is this venue being surveilled”Fine
Logging for a security reportFine, with appropriate data handling
Confronting / approaching the operatorCaution — that’s a human-interaction decision, not a technical one; de-escalation, not vigilantism
Harassing / interfering with a lawful operatorNot OK — and interfering with the drone itself (jamming) is illegal (Vol 11 § 3)

9.3 The nyanBOX-specific note

The nyanBOX’s education framing presents RemoteID detection as a passive awareness tool — and that’s the right framing. It’s a “know what’s in your airspace” capability, not a “hunt the pilot” capability. Vol 11 § 5 carries the full posture.
