CA-GNSS-PRO | High-Precision GNSS Monitoring Receiver

Product Overview

The CA-GNSS-PRO is a dedicated multi-star, multi-frequency GNSS monitoring all-in-one receiver for surface displacement monitoring. With BeiDou-3 (BDS-3) support, high precision, low power and easy installation, it deploys complete monitoring stations powered by a small solar system at under 2W.

Outputs: high-precision surface displacement, acceleration & tilt
Edge computing: RTK, on-device / backend static solving, alarm triggering
Sensor integration: MEMS-triggered RTK; powers & connects RS485 sensors
Storage: built-in storage for >2 years of 15s-raw data
Smart: timed sleep, battery monitoring, remote upgrade & diagnostics
Design: all-in-one, IP68, simple installation, low power
