IBIS-FL is a highly innovative technology for 2D monitoring of displacements and movements in slopes and structures.

Monitoring of terrain movements (unstable slopes, landslides, glaciers, …) is an increasingly important task for today’s geotechnical experts required to prevent or forecast natural disasters that could affect human lives.

IBIS-FL, based on SAR interferometry, can remotely measure the simultaneous displacement of thousands of points over large areas (natural reflections of the slope), without the need for any kind of access to the slope under observation. IBIS-FL provides a Displacement Time Series for each point with an accuracy of up to 0.1 mm. Thanks to the high number and the spatial density of good measurement points, IBIS-FL can also provide Displacement Maps to clearly distinguish stable and moving portions of the area under investigation.

The automatic acquisition and processing of IBIS-FL data enables the device to provide early warning alerts if movements exceed a selected threshold.

This product utilises the IBIS Surveyor Software.


  • Remote sensing: Real time remote sensing at up to 4 km with no need for equipment to be installed on the monitored area.
  • Accuracy: Measures displacements of as little as 0.1 mm @ 4km range. No other instrument can match the same accuracy.
  • 3D rendering: Real time 3D map of displacements over areas of several square kilometers. The user can easily understand and locate the displacements.
  • Always operative: Operates day & night in all weather conditions. The system can operate independently and continuously for really long survey periods.
