A GNSS-based deformation monitoring sensor
The 4DBloc solution from Sixense is a GNSS-based deformation monitoring sensor designed to deliver real-time measurement of ground and structural movement with high precision and reliability. 4DBloc combines robust hardware with dedicated automated algorithms to provide millimetre-level positional data without requiring regular calibration or maintenance. This makes it an ideal solution for long-term monitoring projects where access is limited or environmental conditions are challenging.
4DBloc sensors operate as part of a connected network, with each unit communicating to a gateway station via radio and relaying data in real time over the internet. Using differential GNSS positioning against a stable reference point and advanced processing algorithms, 4DBloc delivers accurate, low-power, and fully automated monitoring of deformation in three axis. Its compact design, low energy requirements, and ability to be powered by solar panels mean the system can be deployed widely and cost-effectively across a range of environments.
4DBloc is used for monitoring critical infrastructure such as bridges, highways and railways, hydraulic and marine structures including dams, dykes and harbours), historic buildings and monuments, and mining operations. By enabling continuous, automatic tracking of movement and deformation, Sixense empowers engineers and project owners to make faster, more informed decisions about safety, maintenance, and assett lifecycle management. Backed by decades of monitoring expertise and integrated with Sixense’s broader data platforms, 4DBloc offers unmatched value, reliability, and actionable insight for projects of any scale.
