3.Surface displacement monitoring system product installation

Installation requirements:

1.There should be no tall buildings around either the base station or the measuring station.If it cannot be avoided, it should be at least 20 meters away.

2.The distance (baseline distance) between the base station and the measuring station is recommended to be less than 500 meters, and the maximum should not exceed 2KM.Try to install them at the same altitude.Excessive distance will lead to a decrease in accuracy.

3.The base station and the measuring station should be as visible as possible.If they cannot be fully visible, high walls, buildings, etc.should be avoided.

4.Prioritize ensuring that the satellite antenna is the highest point within 20 meters.

5.The installation base should be firm to avoid accuracy loss caused by wind.

6.For specific installation matters, you can also contact the company for after-sales video guidance.

Surface displacement monitoring system notes: GNSS displacement monitoring is a high-precision displacement monitoring technology implemented using positioning satellites such as Beidou and GPS.Its monitoring accuracy strongly depends on the relative relationship between the base station and the monitoring station and the electromagnetic environment.Excessive baseline distance will seriously affect the monitoring.Accuracy and even data Invalid (for example: for baseline distances exceeding 2KM or even 10KM, the possible displacement accuracy will be reduced to the 10 cm level due to the influence of the electromagnetic environment and terrain, which is invalid for displacement monitoring).Therefore, in order to ensure measurement accuracy, it is recommended The baseline distance is within 500 meters.
