3DeMoN GPS

The 3DeMoN system was designed to enable the permanent monitoring of millimeter-scale movements. It is based on a network of GPS receivers installed on the object to be monitored and on a Control Center (standard or industrial PC) that oversees the operation of the whole system. The data received from all the measurement and reference stations is processed simultaneously and the relative movement between the stations is than stored in a database. This data can be accessed by authorized operators and used to generate warnings (through SMS, e-mail, …) or further analyzed to obtain information on the movement velocity, direction and acceleration.
The measurement and reference stations are physically identical, but their function is specified at the data analysis stage. Each station can work completely autonomous from power supply (using solar panels) and data transmission (using radio or cellular modems). The installation process is therefore reduced to attaching the GPS antennas and stations to the structure to be monitored. A single Control Center can be used to monitor different sites. It is indicated for continuous deformation or displacement monitoring in the geotechnical and civil engineering fields.
The 3DeMoN system is fully compatible with other SMARTEC products. The results are stored in a standard SDB database and can be integrated with measurements from other sensors (e.g. SOFO, ADAM, …). The user can therefore view and analyze all its data with a single interface.
Application domains:
• Landslide monitoring or land subsidence
• Settlement and subsidence monitoring and other geotechnical applications
• Deformation monitoring of dams, dikes, breakwaters, ...
• Monitoring of large structures like suspension- and cable-stayed bridges, piles, towers, tanks, off-shore platforms,…
• Geological movement detection
