Dashboard

Local-relative map (no tiles). Sensors plot from their GPS lat/lon (oracle-rf-gps feed); each open event with a KrakenSDR DoA bearing draws a ray from its sensor, and two crossing bearings mark a rough fix.

What the spectrum scanner is looking for and what RF emitter family each peak likely belongs to. Every row in the Drone Events / Recent Peaks panels is clickable for a per-peak hint built from this same table.

Band map

Range	Use	Typical BW	Notes
902-928 MHz	LRS control (TBS Crossfire, ELRS 900, DragonLink)	<200 kHz, FHSS	Sub-GHz, no video, long range
2402, 2426, 2480 MHz	BLE advertising (Remote ID per ASTM F3411)	~1 MHz	Decode ODID frame for serial/operator
2400-2483 MHz	Wi-Fi 2.4, DJI OcuSync 2.4 (uplink), ZigBee, BT	20/40 MHz Wi-Fi · 10/20 MHz OcuSync	Crowded; OUI+SSID packet metadata can fingerprint Wi-Fi drones
5150-5350 MHz	Wi-Fi 5 UNII-1 / UNII-2A	20/40/80 MHz	Indoor / low-power
5470-5725 MHz	Wi-Fi 5 UNII-2C (DFS)	20/40/80 MHz	Radar-coexist; rare for drones
5725-5850 MHz	UNII-3, FPV analog, DJI OcuSync 5.8 downlink	4-10 MHz FPV · 10/20 MHz OcuSync	The single most useful band for drone detection
5850-5950 MHz	FPV Raceband R7/R8 (extended)	4-10 MHz	Hobbyist racing

Wi-Fi OUI / SSID fingerprinting

Evidence	Meaning	Reliability
Remote ID	Decoded identity/location/operator payload	Definitive when present
OUI + SSID/probe/beacon match	Passive Wi-Fi fingerprint for known drone/controller families	Strong supporting ID, especially with RF/RID/visual corroboration
SSID-only string	Drone-looking network name without MAC vendor agreement	Lower confidence; review before treating as positive

Likely make & model

Signature	Likely vendor / family	Common models
5725-5850 MHz, BW 10-25 MHz, no Wi-Fi grid, paired 2.4 GHz peak hopping	DJI OcuSync (O2 / O3 / O3+)	Mavic 2 / 3 (all variants), Mini 2 / 3 Pro / 4 Pro, Air 2 / 2S / 3, M30, M300 RTK
2400 MHz half-duplex, BW 10-20 MHz, low occupancy (<70%)	DJI OcuSync uplink (RC→aircraft)	Same DJI lineup — the controller side of the link
5658-5917 MHz on Raceband / Boscam-A grid, BW 4-10 MHz	FPV analog video TX	Eachine TX805, TBS Unify Pro, Foxeer Reaper, AKK, RushFPV, ImmersionRC
On a Wi-Fi 2.4 / 5 channel grid, BW 20/40/80 MHz, no hopping	Wi-Fi drones (any brand)	Parrot Anafi / Bebop, DJI Tello / Spark, Autel EVO Nano / Lite, Skydio 2+ control link, Hubsan, Holy Stone toys
2402 / 2426 / 2480 MHz, BW ~1 MHz	ASTM F3411 Remote ID (BLE)	Any FAA Part 89 compliant aircraft > 250 g
902-928 MHz, BW <200 kHz, fast FHSS	Long-range FPV control	TBS Crossfire, ExpressLRS 900, DragonLink, EzUHF

Confidence taxonomy

• high — bandwidth, channel grid, and (where applicable) hopping behaviour all match a documented signature.
• med — channel + verdict family match; bandwidth tolerant.
• low — only the band matches; many possible emitters.

How to confirm

• Look for a paired peak on the matching band (OcuSync hops between 2.4 + 5.8 GHz; an aircraft will show in both).
• Check the Remote ID panel (BLE / Wi-Fi NaN beacons) for serial / operator location — definitive when present.
• Cross-reference with the Airspace map for ADS-B / DJI cloud telemetry on the same target.
• Track age & consecutive-scan count distinguish a hopping aircraft from a stationary access point.
