The Livox Avia is a 905 nm LiDAR from China for light UAV mapping systems such as the YellowScan Mapper+. It is a scanner for mid-sized multicopters and delivers multiple echoes at low weight.
The Avia reaches 320 m at 80 % reflectivity and 190 m at 10 % reflectivity. The point rate rises with the echoes: 240,000 per second with one echo, 480,000 with two and 720,000 with three. Multiple echoes capture ground and vegetation at once. The field of view is 70.4 × 77.2° in the non-repetitive pattern, in which scan lines do not repeat and coverage becomes denser over time, or 70.4 × 4.5° in line scan. Precision is 2 cm (1 sigma at 20 m). A BMI088 IMU is built in, a GNSS is not. The unit weighs 498 g without cable.
The weight of the scanner alone stays below 900 g, the limit of EU class C1; the total take-off mass of the aircraft is decisive. The scanner is a laser device, and the laser class given by the manufacturer is to be observed. Point clouds of built-up areas fall under data-protection law when people or property become recognisable.
The built-in IMU suffices for motion correction and close-range mapping (SLAM); for georeferenced data in the field, an external GNSS is added, as complete systems like the Mapper+ bring. The non-repetitive pattern gives broad coverage, the line scan a more even line structure. The scanner window must be kept clean, the mount rigid and low-vibration; connectors and cables are points to check.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Ask about parts availability for this build year — the running costs hang on it.
