4DBloc ™ is a GNSS-based sensor that provides real-time monitoring of ground surfaces and built structures.
4DBloc ™ was developed and tested in cooperation with the French National Institute of Geographic and Forest Information (IGN) with the shared aim of creating a GNSS-based position measurement system that is robust, simple, cost-effective and accurate.
4DBloc™, the accurate, robust and economical GNSS deformation sensor
Requiring no calibration or special maintenance, 4DBloc ™ is a very simple sensor, and unlike other sensors in this family, requires no regular maintenance.
It also consumes very little energy, and can be powered by a single solar panel installed at the same time.
It is the ideal instrument for the long-term monitoring of locations where access is challenging.
4DBloc ™ data is processed by a dedicated, unique and fully automated algorithm to deliver a level of accuracy within a few millimetres, depending on circumstances and location.
4DBloc™ and its applications
4DBloc ™ applications include:
- Transport infrastructures: bridges, rails, roads, etc.
- Hydraulic infrastructures: dams, coastal defences, harbours, etc.
- Historic buildings and monuments
- Mines
Principle of operation
The 4DBloc™ solution gives you:
- A robust system with a small footprint and low power consumption
- The best GNSS-based deformation system on the market
- Unrivalled value for money
