GNSS sensor

1.Introduction to GNSS sensor product

GNSS sensor is a compact autonomous sensor that incorporates a GNSS receiver to provide accurate displacement measurements to monitor changes in objects in extreme climates.GNSS sensor is a millimeter-level displacement monitoring product implemented using differential RTK technology.It can be widely used in engineering fields such as dam safety monitoring, bridge health detection, landslide warning, etc.This product has high precision, high stability and real-time data transmission capabilities, and can accurately monitor the tiny displacement changes of target objects in various complex environments.The GNSS displacement station is simple to operate and convenient to install, and can be remotely monitored and analyzed, providing strong guarantees for engineering safety.In addition, its powerful data processing capabilities and compatibility make this product easily integrated into various monitoring systems, realizing data sharing and convergence, and providing comprehensive and efficient solutions for engineering safety monitoring.

3.Installation of GNSS sensor products

Installation requirements:

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

2.The distance between the reference station and the measurement station (baseline distance) is recommended to be less than 500 meters, with a maximum of no more than 2KM, and try to choose to install it at the same altitude.If the distance is too large, the longitude will drop.

3.Try to be visible between the reference station and the measurement station.If it is not fully visible, avoid obstruction of high walls, buildings, etc.

4.The antenna should be ensured that the maximum point within 20 meters.

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

6.The height of the digital transmission antenna and lora antenna should not be higher than the measurement antenna, and should be kept away from the measurement antenna as much as possible.To ensure the accuracy of subsequent measurement, you can also contact the company's after-sales video guidance for specific installation matters.
