3、 Product installation

Installation requirements:

1. There should be no tall buildings around the reference station or measurement station, and if unavoidable, they should be kept at least 20 meters away.

2. It is recommended that the distance between the reference station and the measurement station (baseline distance) be less than 500 meters and no more than 2KM, and installation at the same altitude should be chosen as much as possible. If the distance is too large, it will lead to a decrease in accuracy.

3. The distance between the reference station and the measurement station should be visible as much as possible, and if it is not visible, high walls, buildings, and other obstructions should be avoided.

4. Prioritize ensuring that the satellite antenna is at a high point within 20 meters.

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

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

Attention: GNSS displacement monitoring is a high-precision displacement monitoring technology that utilizes positioning satellites such as Beidou and GPS. Its monitoring accuracy strongly depends on the relative relationship between the reference station and the monitoring station, as well as the electromagnetic environment. Long baseline distances can seriously affect monitoring accuracy and even render data invalid (for example, for baseline distances exceeding 2KM or even 10KM, the displacement accuracy may be reduced to the level of 10 centimeters due to the influence of electromagnetic environment and terrain, which is ineffective for displacement monitoring). Therefore, to ensure measurement accuracy, the recommended baseline distance is within 500 meters.
