GNSS Receiver
BGK-2850 GNSS receiver is an integrated, high-precision surface displacement measurement system based on the Global Navigation Satellite System (GNSS). Its main function is to monitor the three-dimensional displacement changes of the measured object through real-time calculation of GNSS data.
BGK-2850 GNSS receiver is an integrated, high-precision surface displacement measurement system based on the Global Navigation Satellite System (GNSS). Its main function is to monitor the three-dimensional displacement changes of the measured object through real-time calculation of GNSS data. The system is applicable for displacement and deformation monitoring of large structures such as dams, tailings storage facilities, landslides, bridges, and ground subsidence in mine goafs.
This device supports multiple systems and frequencies including BDS, GPS/QZSS, Galileo, and GLONASS. It integrates dual-frequency RTK algorithms internally, providing stable centimeter-level high-precision positioning services. It supports WIFI, wired network, and 4G remote transmission. The device offers flexible power supply options, including AC mains power and solar power, making it suitable for most field environments where 220 V AC power is not available.
