Lxnav

What Lxnav does

LXNAV d.o.o. is a Slovenian designer and manufacturer of specialized aviation electronics, headquartered in Celje and operating since 2009 with an 11–50 person team. The company builds high-performance navigation systems, variometers, IGC-compliant flight recorders, FLARM collision-avoidance devices, and supporting software, primarily for the global sailplane/gliding community and adjacent segments including powered general aviation and marine electronics. Its technology stack combines ARM-based embedded processors, GPS, FLARM/PowerFLARM collision-avoidance protocols, ADS-B receivers, AHRS sensor fusion, and proprietary algorithms for live wind calculation, ENL engine-noise logging, and flight performance analysis. Key certifications include ISO 9001 quality management, EASA Supplemental Type Certificate (STC) approval for the ADI2 instrument, and IGC approval for the Nano-series flight recorders, which together enable installation in certified aircraft and use in official badge and competition flights.

LXNAV operates three sub-brands: LXNAV Gliding (the core soaring business), LXNAV Marine (marine electronics, including the 2026 DAME Award-winning round chartplotter), and LXNAV Ultralight (ultralight aviation), plus a software platform branded LXNAV Connect. The business model is hardware-centric: products are sold as complete units with associated firmware updates, configuration software, and recurring airspace/airport database subscriptions. Distribution is exclusively through a global authorized dealer network that handles installation, configuration, and support rather than direct-to-consumer e-commerce. Strategic OEM-level integration with Alexander Schleicher sailplanes and deep integration with FLARM Technology's collision-avoidance ecosystem form the backbone of customer stickiness. The company is founder-led by Erazem Polutnik, privately held without disclosed venture capital or private equity backing, and supplements R&D with Slovenian and EU grant programs.

• Triadis Engineering: Swiss firm developing FLARM-based traffic displays and accessories (e.g., PowerFLARM-related products). Overlaps with LXNAV's FlarmView and TrafficView line.
• LX Stodeus / Stodeus: French manufacturer of gliding variometers and IGC flight recorders. Comparable product line for IGC-approved recorders and competition variometers serving European gliding clubs.
• Borgelt Instruments: Australian designer and manufacturer of variometers and flight computers for gliders and powered aircraft. Direct peer in the soaring variometer and flight computer category.

Broad incumbents

• Avidyne: US-based avionics manufacturer producing certified and experimental IFR navigators and displays. Competes indirectly as LXNAV pursues EASA STC expansion into certified aircraft.
• Garmin: Dominant general-aviation avionics incumbent with portable and panel-mount GPS navigators that increasingly target the soaring/GA crossover. Sets the competitive ceiling on pricing and feature expectations.
