Wuhan Zhongdi Hengda -- GNSS Receiver
(1) Product Introduction
The GP30 general-purpose GNSS receiver is a professional high-precision receiver launched by Zhongdi Hengda Technology for the surface displacement monitoring and deformation monitoring application markets. It supports multi-system and multi-frequency points including BDS, GPS, GLONASS, etc., and supports dual-frequency RTK algorithm, which can achieve high-frequency dynamic centimeter-level monitoring and also achieve high-precision static millimeter-level monitoring. The GP30 integrated receiver has high integration, high precision and high cost performance. It adopts an integrated built-in GNSS/4G/Wi-Fi antenna, built-in temperature and humidity sensor and MEMS sensor, and supports combined monitoring of acceleration, inclination and GNSS. It is a cost-effective professional millimeter-level positioning receiver.
