IBIS-S
An innovative solution for static and dynamic structure monitoring

Orbit Geological Consultancy (OGC) introduces IBIS-S, an innovative radar for  remotely  monitoring  structure  movements  and  deformations,  based  on microwave interferometer

Structure displacement and measurement collapse hazards.
Structural modal shape Cultural heritage preservation analysis
Monitoring  of  structure  movements  and  vibrations  (bridges, buildings,  monuments,  towers  etc.)  Is an increasingly important task for today’s construction engineers

IBIS-S introduces  a  totally  new  solution  in  this  field  of  application, with  many  advantages  over  traditional  instruments  for  both static and dynamic monitoring.Testing of new structures, maintenance and preservation monitoring of existing ones, monitoring of structures subject toNatural hazards  (e.g.  landslides,  subsidence)  or  those  caused artificially  (e.g.  tunnel  construction,  large  civil  engineering projects) will all greatly benefit from the use of IBIS-S.

IBIS-S  can perform continuous, real time mapping of  all  displacements  of  the  entire  monitored structure  with  sub-millimeter  accuracy  and  at  a distance of up to 1 km. All these displacements can be  monitored  and  mapped  simultaneously,  as opposed to traditional point-by-point techniques.The same instrument can be used to monitor both slow  displacements  (“static  regime”)  and  structure

The IBIS-S radar beam enables simultaneous
vibration  modes  (“dynamic  regime”),  another unique  feature  of  IBIS-S  radar  interferometric mapping of displacements of different points technology.

across the entire structure
A  hole  bridge,  a  monument  or  a  tower  can  be remotely  monitored  using  a  single  IBIS-S  system. Slow displacements and deformations due to terrain subsidence, aging and structural problems, included stress, as well as structure vibrations (up to 100 Hz) can all be  remotely  monitored,  with  no  need  to place sensors or cables on the structure.

Advantages over traditional techniques:
Remote sensing at a distance of up to 1 km.

Static monitoring
Displacement accuracy up to 1/100 mm. Real-time  one-dimensional  simultaneous mapping of all displacement detected on thestructure.
Fast installation and operation.
The  same  instrument  can  be  used for  static and dynamic monitoring.
Structure vibration sampling up to 100 Hz.
Operates  day-night,  in  all  weather conditions.
