Ainstein’s US-D1 radar altimeter is ideal for providing high-precision, real-time altitude readouts to industrial and tactical UAVs. Because of its unmatched effectiveness in enabling efficient, reliable, and safe Vertical Take-Off & Landing (VTOL) transitions, it has become the gold standard for drones performing VTOL.

Who the US-D1 is ideal for:

  • Recon and Surveillance Drone Manufacturers
  • Lightweight, Fixed-Wing Tactical UAS
  • Other VTOL Drone Applications

Why Use a Radar Altimeter?

  • To perform high-fidelity UAV terrain-following
  • Laser altimeters are less effective over water
  • GPS can’t account for varied terrain

Key Benefits of US-D1 for VTOL Drones:


  • Rapid, real-time data (100 Hz Refresh Rate)
  • Small size (108 x 79 x 20mm)
  • Lightweight (110g)
  • Simple and easy setup (Ardupilot and PX4 ready)
  • Ideal for autonomous takeoff and landing (0.3m – 50m operating range)

US-D1: UAV Standard Radar Altimeter

Ainstein’s UAV Standard Radar Altimeter US-D1 is a must-have mmWave Radar sensor, enabling autonomous takeoff and autonomous landings for drones, as well as terrain tracking commonly required for precision agriculture.

LR-D1: UAV Long Range Radar Altimeter

Ainstein UAV Long Range Radar Altimeter LR-D1 is a low-cost, high-performance mmWave Radar altimeter designed for advanced unmanned aerial vehicles (UAVs), manned helicopters, and other GA aircraft.

LR-D1 Pro: The latest generation of our long-range radar altimeter.

The LR-D1 Pro employs a 60 GHz antenna for centimetre-level precision at low altitudes and a 24 GHz antenna for enhanced capabilities at high altitudes. The LR-D1 Pro is ideal for larger UAVs performing VTOL, helicopters, and for missions that require precision landing and ruggedized durability.
