Safety Tips
1. The laser used in this device is a Class 1 laser product, so there is no need for
personal protective equipment. It has been certified for eye safety by CB and
complies with the IEC60825-1:2014 standard.
2. To ensure the safety of the operator and the device, please read this manual
carefully before use and ensure that you have received qualified operational
training. (Not to be used by individuals under 18 years of age)
3. Do not use the device if there is noticeable noise, alarm sounds, or damage.
Contact the manufacturer's technical personnel for repairs in a timely
manner. Forced use may cause permanent damage to the device.
4. Follow the operating instructions, suggestions, warnings, or precautions
provided by the manufacturer in this manual, among others.
5. This device operates at a voltage of 12~24V, 1A@24VDC. Do not use power
supply equipment outside this voltage range to prevent danger and
permanent damage to the device.
6. Keep the power, USB, network cable, and other connectors clean and dry. Do

not insert objects other than the corresponding plugs.
7. Do not disassemble the device or replace parts not provided by the
manufacturer without authorization, as this may cause danger and damage
to the device. If disassembly is required, please contact the manufacturer and
proceed under the guidance of the manufacturer's technical personnel.
8. This device is a precision instrument. Handle it with care, unload it from the
platform, and transport it in a dedicated transport case.
9. The device should be stored in a cool and dry place. Clean it after use and
make sure to disconnect the power during cleaning.
10. The operating temperature of this device is -20~50. Measurements may be
inaccurate, data may be lost, or the device may be damaged if operated
below or above this temperature range.
11. Before using the device, ensure that the operating environment is free from
electromagnetic interference. Please refer to the user manual for specific
standards.
12. There are specific guidelines for the use and storage of batteries. Please refer
to the lithium battery use/storage guidelines.
13. This device is a precision electronic instrument. Do not dispose of it carelessly.
When the device is scrapped, do not throw it directly into the trash. You can
send it back to the manufacturer for disposal, or you can handle it yourself in

2 Product Introduction
The LiAir 220 adopts an integrated design scheme, integrating a 40-line circular
scanning LiDAR, an inertial navigation system, and a built-in 2600W
high-resolution mapping camera. Paired with GreenValley's self-developed
software such as LiPlan/LiGeoReference, it can provide integrated solutions for
emergency mapping, forestry resource surveys, power inspections, and other
fields.
1. A dynamic differential GNSS receiver used to measure the spatial position of
the reference point of the LiDAR signal emission.
2. An attitude measurement device, i.e., an inertial navigation device, used to
measure the attitude parameters of the main optical axis of the scanning
device.
3. A laser rangefinder is used to measure the distance from the reference point
of the LiDAR signal emission to the ground laser foot point, which is the core
part of the entire integrated system, i.e., the laser scanning head.

4. A storage control system is used for data storage, device control, receiving
signals sent from the ground to the airborne end, and controlling device
parameter adjustment, data collection, and download functions.
5. A power system is used to supply power to the entire device.
Working Principle of the Product:
1. The system controls the device to collect data by receiving and executing
commands sent by the hardware switch or the LiPlan flight assistant.
2. All the collected raw data is stored in the TF card. After data collection is
completed, it is copied to the local computer for data processing.
3. The LiGeoreference software is used to fuse the position and angle
information in the LiDAR system coordinate system with the POS data to
obtain accurate geographic coordinates.
