LiAir 220N UAV-LIDAR system is a light-weighted (2.0 kg incl. camera) and 3D surveying and mapping
instrument designed to be mounted to multi-rotor aerial platforms (DJI M300 & DJI M600). LiAir 220N
provides accuracy point cloud data for users in various industries including topographic surveying,
forestry, vegetation management, power line inspection, and many more. For additional information

2.2 System Basics
The LiAir 220N system integration is comprised of multiple technologies, including:
➢
Laser Scanner (LIDAR sensor)
➢
GNSS (Global Navigation Satellite System)
➢
IMU (Inertial Measurement Unit)
➢
System Control and Storage Unit
➢
Power Supply and Management Unit
The GNSS unit and IMU unit together form what is often referred to as
the LiAir 220N
’s POS Module.
2.3 System Principles
➢
In operation, the System Controller receives and executes operational commands that control
the collection of data by each of the LiAir 220N
’s integrated sensors and measurement
devices.
➢
The POS Module (GNSS and IMU) determines LiAir 220N
’s position and a
ttitude at any given
point in time. This time-series position and attitude data is commonly referred to as the LiAir
220N
’s trajectory or POS data.
