Millimetre precision from orbit, for land and infrastructure.
Millimetre precision
We watch the terrain move, one millimetre at a time
With SAR interferometry and a proprietary algorithm we measure from orbit the millimetric displacements of schools, cultural heritage and critical infrastructure, installing nothing on the buildings: the historical series reconstructs settlement dynamics and lets us step in before damage becomes visible.

In brief
SAR satellite interferometry with a proprietary algorithm for millimetre level monitoring of schools, cultural heritage and critical infrastructure.
With SAR satellite interferometry and a proprietary algorithm, we measure millimetre scale movements in buildings and land: schools, cultural heritage and critical infrastructure, monitored continuously from orbit and without ground sensors.
Context
The European Space Agency's constellation of SAR satellites gathers information on the elevation and displacement of targets across the national territory. The data, processed through mathematical models of the terrain, makes it possible to track, with millimetre precision and in every direction, the movements of the ground and the buildings involved.
This monitoring makes it possible to prevent hazardous situations and to intervene promptly and cost effectively wherever necessary.
Areas of application
The system is suited to large scale surveys covering school buildings, prestige properties, cultural and archaeological heritage, and critical infrastructure. Access to the historical database makes it possible to reconstruct the dynamics of subsidence, the impact of underground works and hydrogeological risk analyses.
Benefits
- monitoring with millimetre precision in every direction
- no instrumentation installed on the building
- cost savings through timely intervention, before damage becomes visible
