The RF spectrum, fused onto one map.

Crewed aircraft on 1090 MHz, RemoteID drones, AIS vessels, APRS, Marine VHF / NOAA / CB — wrap proven demodulators and fold every track into one COP. Receive-only by design.

Passive collection, active picture

Wrap the demodulator. Own the picture.

Purpose-built for UAS ops and wildland fire — crewed aircraft, TIS-B, and RemoteID on one screen. App owns demodulator lifecycle; SSE to the map; DuckDB history.

ADS-B & RemoteID

readsb / dump978 on 1090 + 978 MHz — drones as orange-red diamonds with operator ID.

AIS vessels

rtl_ais + NMEA VDM/VDO — maritime traffic on the same scene.

APRS RF + IS

Positions, weather, objects, messages — RF via rx_fm + multimon-ng, plus APRS-IS.

Audio & IoT

Marine VHF, NOAA SAME/EAS, CB/GMRS/MURS · rtl_433 ISM sensors.

DuckDB hub

Every packet becomes a queryable layer

sdr.duckdb / aprs.duckdb — OGC Features, MVT, FeatureServer
Four ingest topologies: HackRF, Beast, SBS1, aircraft.json poll
One SDR = one tuner — run one RF module at a time per device
Receive-only by design — no transmit

Hear the spectrum. See the picture.

Plug in an SDR, add a receiver from the in-map panel — aircraft, drones, vessels, and radio traffic on the same 3D scene.
