Ainstein Announces Full Stack PX4 Support For UAV Standard Radar Altimeter US-D1

The world’s lightest, smallest UAV radar altimeter is getting a lot of attention! Ainstein has just announced full PX4 flight stack support with its UAV radar altimeter – US-D1.  

This capability allows PX4 developers to fully benefit from Ainstein’s highly accurate and reliable above-the-ground altitude measurement and access the same technology that has been proven by leading agriculture drone manufactures. Ainstein’s UAV radar altimeter has also been recognized by FAA’s Integration Pilot Program.

Curious what all the buzz is about? Here is a quick snapshot of the highlights for Ainstein’s US-D1 radar altimeter:

  • Highly accurate and smooth above-the-ground altitude reading, especially over water, grass, brush, and other challenging environments.
  • Same high performance in low-light or no light conditions, such as rain, fog, darkness, and more.
  • Customer-proven for accurate terrain tracking commonly required for precision agriculture.
  • A must-have for BVLOS drone operation, ensuring safe or even autonomous takeoff and autonomous landing.
  • Increased Processing:  Increases in processing power have resulted in even more reliable altitude readouts, greatly reducing noisy or false detections.
  • Ruggedized Enclosure: Drones crash, propellers break, but the US-D1 should not!  Worried about your expensive UAV electronics getting coated in mist from agricultural spraying? Or covered in dust during takeoffs and landings? Worry no more, US-D1 is rated IP-67!
  • Redundancy Capabilities: Ainstein’s technology allows for running multiple US-D1 altimeters on a drone for sensor redundancy configuration, or sensor multiplexing for enhanced detection, all without having to worry about cross-radar interference.  

US-D1 Specifications Highlights:

  • Operating Range: 0.5 ~ 50 meters
  • Altitude Accuracy: 0.5 centimeters
  • Weight: 100 grams
  • Power Consumption: 2 watts with 5 volt supply

Steps for Integration with PX4:

  1. Connect US-D1 to any available Serial Port(UART), eg TELEM3, or GPS2
  2. Configure the Serial Port you’ve selected
  3. Add this Parameter to your Config File: “drivers/distance_sensor/ulanding”
  4. Enjoy the flight!
