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.
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 applications include:
Each 4DBloc sensor communicates with a gateway station using a radio transmission.
The gateway station transfers the data in real-time automatically via the internet.
The millimetric position is possible utilising two parameters:
developed from 20 years of experience and in-house development
as a result of our extensive network
from installation to provision of pre-processed data in an accessible webspace
committed to the continual development of solutions more closely aligned with the practical challenges of our clients
built around data quality control and monitoring
