Deformation Monitoring

GNSS based monitoring system

The GNSS based monitoring system is widely applied in the fields of landslide geological hazard monitoring, dam deformation monitoring, mining area surface subsidence monitoring, tailings reservoir deformation monitoring, bridge deformation monitoring and high-rise building deformation monitoring and other fields with potential safety hazards.

Deformation Monitoring

GNSS based monitoring system

Deformation Monitoring drives the U6 Universal Monitoring All‑in‑One Machine, Toknav’s independently developed GNSS receiver built for geological disaster monitoring and early warning. Its compact, highly integrated form enables fast installation and minimal maintenance. Ultra‑low power design cuts battery and solar panel capacity needs, greatly reducing site construction and long‑term operation costs.

At its heart lies a Linux + Qualcomm Cortex‑A7 intelligent platform, delivering robust computing power and endless scalability. The integrated high‑precision, low‑power GNSS module supports BDS, GPS, GLONASS, Galileo and QZSS multi‑constellation positioning. 4G full‑network connectivity ensures stable, high‑compatibility 2/3/4G links for consistent data delivery.

Integrated high‑precision three‑axis accelerometer and barometer work with a refined fusion algorithm engine to eliminate false alarms and enable reliable medium‑to‑long‑term early warning. Boasting IP68 protection, wide −40℃ to +85℃ operation, and 1.8W ultra‑low power, it maintains stable performance in harsh outdoor environments.

The U6 features full cloud connectivity, automatically reporting position, network status, signal strength and satellite lock. It supports remote restart, configuration and firmware upgrade. With RS232/RS485, Bluetooth, Wi‑Fi and LoRa, plus 32GB storage, it provides a complete, high‑reliability deformation monitoring solution.

System Architecture
