To safely integrate drones into airspace shared with manned aviation is a demanding challenge for the industry. Leveraging the new FLARM Atom platform, Atom UAV is a comprehensive, fully-featured FLARM system in a tiny package, providing detect & avoid with more than 50,000 manned aircraft. Atom UAV combines a FLARM radio transceiver, an ADS-B receiver, and a Wi‑Fi transmitter for direct-broadcast Remote ID, compliant with ASTM F3411-19. Atom UAV complies with the relevant FCC and EN/ETSI standards.

Atom UAV is available in two versions: OEM and Standalone. The OEM version is free of any enclosure and can be directly integrated into own designs: M3 mounting holes in a 30.5 mm grid and the board-to-board connector allow for stacking with other modules or on a carrier board. The standalone version has an enclosure and uses the JST-GH connector used by many UAV flight controller platforms. Both versions stream traffic information in either the MAVLink or JSON protocol formats.

Atom UAV implements the ASTM F3411-19 standard for remote ID, based on direct-broadcast Wi‑Fi. An additional Remote ID implementation based on FTD-129 is available.

Traffic information is output via Wi-Fi or serial port in a unified stream, merging ADS-B and FLARM traffic and dynamically selecting the source of higher quality. Multiple streaming formats are available: JSON, MAVLink, and GDL90.

On MAVLink-based systems, Atom UAV delivers HEARTBEAT and VEHICLE_ADSB messages. It further implements the configuration interface via the PARAM_REQUEST_xxx mechanism. Systems supporting the GPS_RAW_INT and SYSTEM_TIME messages can override the built-in GNSS receiver and inject their own navigation solution.
