1.3 Use and precautions
Although the VNet series (ground-based) GNSS receiver is based on
military standard design, it is anodized with an aluminum alloy, but the
precision instruments require careful use and maintenance.
WARNING: The receiver must be used and stored within
the specified environment. Please refer to the Appendix:
VNet product technical performance parameters table.
Avoid using the receiver in extreme environments.
The VNet6 Plus (ground-reinforced) GNSS receiver uses anodized
aluminum alloy for the shell, but should also be kept as dry as possible.
And in order to improve the stability of the receiver and extend the service
life, please avoid the receiver exposed to extreme environments, such as:
1. Damp
2. The temperature is higher than 75 ℃
3. The temperature is less than -40℃
4. Corrosive liquid or gas

Do not place the GNSS antenna near sources of electricity and strong
interfering signals:
1. Oil (spark plug)
2. TV and computer monitors
3. Generator
4. Electric motorcycle
5. DC - AC power conversion equipment
6. Fluorescent light
7. Power switch
When selecting the position of the GNSS reference station for continuous
operation, notice the following:
The site should be easy to place the receiving device and have a wide field
of vision. Field height above 10 degrees should not have obstacles, so as
not to absorb or block the GNSS signal, as shown in Figure 1-1:
Figure 1-1
1.Near the site should avoid the large area of water or strong interference
with the satellite signal, to reduce the impact of multi-path effect.
2.The site should be away from high-power radio transmission sources
(such as television stations, microwave stations, etc.,) it's better to keep a

distance more than 200m; away from high-voltage transmission lines, the
distance should more than 50m to avoid electromagnetic interference on
the GNSS signal.
3.To provide a stable device to fix the antenna.
4.To provide reliable and stable power supply and communication network.
5. Suitable placement and protection of GNSS reference station equipment.
6.Select the traffic developed place, easy to arrive for inspection and
