Two radar altimeter series — 24 GHz and 60 GHz — covering every UAV altitude sensing need from close-range millimeter precision to long-range 3,300 ft detection.
AxEnd offers two complementary FMCW radar altimeter series to meet the full spectrum of UAV altitude-sensing requirements. The 24 GHz AXDXM24A1 Series delivers long-range detection up to 3,300 ft with wide-beam coverage, ideal for high-altitude and terrain-following missions. The 60 GHz AXDXM60A1 Series achieves millimeter-level (±0.4 in) accuracy in an ultra-compact, ultra-light, ultra-low-power package — purpose-built for close-range precision altimetry.
Both series feature native MAVLink / DroneCAN support, AI-empowered target clustering, rugged IP67 all-weather enclosures, and effortless integration with popular flight controllers.
Both altimeter series share a common technology platform — FMCW radar core with AI-powered processing, ruggedized for all-weather operation, and engineered for seamless integration with industry-standard flight controllers.
Both series use Frequency Modulated Continuous Wave (FMCW) technology for direct terrain-referenced altitude measurement — immune to GPS drift, barometer lag, and sonic interference. The result: real-time, drift-free altitude data you can trust.
AI algorithms intelligently filter noise and suppress interference from multipath reflections, vegetation, and ground clutter. The altimeter adapts to changing environments in real time — delivering clean, reliable altitude data in complex terrain without manual calibration.
Native MAVLink / DroneCAN support with TTL UART and CAN interfaces. Both series integrate directly with PX4 and APM flight controllers, enabling plug-and-play deployment with minimal configuration.
Both altimeter series are fully sealed to IP67 and operate reliably in rain, fog, dust, smoke, and extreme temperatures — day or night, in any climate. No performance degradation from light conditions, precipitation, or airborne particulates.
Four range-configurable models, wide ±24° beam coverage, and triple-protocol support — the 24 GHz series is purpose-built for long-range UAV missions where range flexibility and broad terrain coverage matter most.
±0.4″ (±10 mm) accuracy, 30 g weight, 0.2 W power — the 60 GHz series redefines what a precision altimeter can be, delivering millimeter-level performance in a package smaller than a business card.
GPS gives you a height above a mathematical model. Barometers guess from air pressure. Our FMCW radar measures how far the drone actually is from the ground — directly, accurately, and in any weather.
Our radar measures height above the actual terrain (AGL). GPS gives ellipsoidal height, barometer infers from pressure — both are indirect approximations.
±0.8 in (20 mm) accuracy. GPS degrades under tree cover and in urban canyons; barometers drift with temperature and pressure. Our radar is consistently precise.
Works in GPS-denied environments — inside warehouses, under bridges, in dense forests. Fully autonomous, no external infrastructure required.
IP67-rated. Unaffected by rain, dust, fog, smoke, or darkness. From −40 °F to +158 °F, the reading stays reliable in any condition.
No calibration needed. Barometers drift with weather fronts; our radar holds the same reading whether it’s sitting on the ground or mid-flight.
10–45 Hz refresh, native MAVLink / DroneCAN / ARLink, direct UART & CAN. As light as 99 g and as low as 1.5 W — an easy upgrade for any UAV.
Complete parameter comparison across the five available models. The 24 GHz series offers four range options with wide-beam coverage; the 60 GHz series delivers unmatched precision in a fraction of the size and power.
