What FLARM Technology Ltd does

FLARM Technology Ltd is a privately held Swiss aviation technology company founded in 2004 by three pilot-engineers — Urs Rothacher, Andrea Schlapbach, and Urban Mäder — in response to mid-air collisions in European gliding. The company designs, manufactures, and licenses a GPS-based predictive collision warning system used in general aviation aircraft and unmanned aerial systems. Its core technology continuously measures an aircraft's position and heading via a built-in GPS receiver, derives a predicted flight path, and broadcasts that path via digital radio once per second; nearby FLARM-equipped devices compare trajectories and alert the pilot only when an actual conflict exists within an 18-second lookahead window. The product portfolio spans PowerFLARM devices for manned aircraft (Fusion for certified installation, Flex and Portable for transferable use, Core as an OEM module) and drone-specific products (Aurora and Atom UAV) with Remote ID compliance under ASTM F3411-19 and EN 4709-002.

The business combines one-time hardware sales through authorized dealers and Part-145/Part-M maintenance organizations with recurring software and data revenue: perpetual feature licenses (antenna diversity, IGC flight recording, noise level detection, audio output, Garmin TIS), annual obstacle database subscriptions covering regions such as the Alps, Europe, Norway, and Slovenia, and EASA Minor Change Approval documentation packages for installation in certified aircraft up to 5,700 kg MTOM. Distribution is split between a channel-led model for installed products and a direct-to-consumer webshop (shop.flarm.com) for licenses, databases, and accessories; an OEM/licensing program (Atom System-on-Chip, PowerFLARM OEM Module, libFLARM, FAMP public protocol) extends reach into third-party avionics. The company is founder-controlled, has no disclosed external funding, and reports an installed base exceeding 85,000 manned aircraft (over 50% of European GA) and 20,000+ drones across 50+ countries. The customer base is a long tail of individual pilots, flight schools, and a growing set of commercial drone operators and UTM integrators (notably Droniq), with no significant enterprise revenue concentration.

Core offering

FLARM designs, manufactures, and licenses a proprietary GPS- and radio-based collision warning system for general aviation aircraft, rotorcraft, gliders, and unmanned aerial vehicles. Its PowerFLARM hardware family (Fusion, Flex, Core, Portable) and drone products (Aurora, Atom UAV) detect nearby FLARM-, ADS-B-, and transponder-equipped aircraft, predict collision trajectories up to 18 seconds ahead, and alert pilots only when actual conflict is detected. The company also sells annual obstacle databases, optional software feature licenses, OEM modules, and the FLARM Hub configuration platform, supported by EASA Minor Change Approval packages for certified aircraft installations.

Product overview

FLARM Technology Ltd provides a comprehensive collision avoidance ecosystem for general aviation and drones. The product portfolio centers on PowerFLARM devices (Fusion, Flex, Core, Portable) for manned aircraft, offering different form factors for permanent installation or portable use. For drones, FLARM offers Atom UAV and Aurora products with Remote ID compliance. The ecosystem includes OEM modules (Atom System-on-Chip, PowerFLARM OEM) for manufacturer integration, developer tools (libFLARM, FLARM FAMP Protocol), and complementary services (obstacle databases, ADS-L electronic conspicuity). All Wi-Fi-enabled devices are managed via FLARM Hub web interface and mobile app. The company was founded in 2004 by three Swiss pilots/engineers following glider mid-air collisions.

Expansion highlights6 records

Broad incumbents

• L3Harris Technologies:
• Avidyne:
• Honeywell Aerospace: Honeywell manufactures TCAS and traffic awareness systems for commercial and business aviation. A broad incumbent in the avionics surveillance and identification space; while focused on IFR/TCAS, its traffic management products compete in adjacent regulatory frameworks to FLARM's VFR collision warning.
• Garmin: Garmin is the dominant avionics OEM, offering ADS-B and traffic awareness products (GDL 39, GTX series) integrated into broader cockpit suites. Overlaps with FLARM in traffic detection and electronic conspicuity for general aviation, but addresses a much wider portfolio and the IFR/transponder market rather than the VFR niche.

Emerging players

• Droniq: Droniq provides UTM and drone traffic management solutions in Germany, integrating FLARM transceivers into their Hook-on-Device. A core technology partner that is also an adjacent player in the broader drone detect-and-avoid ecosystem that FLARM serves.
• Sagetech Avionics: Sagetech produces transponders, ADS-B, and detect-and-avoid systems for commercial and military drones. Direct overlap with FLARM's drone product line in the BVLOS and Remote ID segments, with a focus on certifiable UAV avionics.
• Aerobits: Aerobits develops miniature ADS-B and FLARM transceivers for UAVs (notably a combined 14-gram ADS-B/FLARM device). A technology integration partner of FLARM, Aerobits increasingly overlaps with FLARM in the small-drone collision-avoidance segment.
• FreeFlight Systems: FreeFlight Systems manufactures ADS-B avionics for GA, business, and military aviation. Competes with FLARM at the hardware level for ADS-B-based traffic awareness, with greater focus on certified transponders and rule-compliant equipment.

Direct peers

• uAvionix: uAvionix produces ADS-B transceivers, Remote ID solutions, and detect-and-avoid equipment for both manned and unmanned aircraft. Directly competes with FLARM's Atom UAV and Aurora product lines in the drone segment and overlaps in low-cost ADS-B hardware for GA.
• PilotAware: PilotAware is a UK-based electronic conspicuity system for GA aircraft and a direct competitor in the European VFR collision-avoidance segment. FLARM and PilotAware have a formal interoperability partnership, but each competes for the same pilot user base.
