SIXENSE’s CYCLOPS Automatic Total Station is a proven solution for continuous automated 3D monitoring of surface and sub-surface structures:


  • It provides remote 3D movement measurement with sub-millimetric accuracy
  • It also enables theodolites to be grouped within a globally unstable environment to deliver guaranteed nominal accuracy


CYCLOPS is the world’s leading automated topographic measurement method in terms of projects completed and result quality.



CYCLOPS, automated topography

Our CYCLOPS automatic total station system has the ability to control the latest robotic/automatic  total stations to remotely monitor movements in three dimensions and/or perpendicular to a surface with sub-millimetric accuracy.

SIXENSE’s solutions include the option to group theodolites together in order to cover larger surface areas and guarantee delivery of the required level of accuracy.

Our experience, and constant quest for data quality, allows us to achieve superior levels of reliability, precision, repeatability and accuracy As a result we are often called upon to remediate third-party facilities.

CYCLOPS and its applications

Any project or structure affected by absolute deformation (3-dimensional monitoring) or relative deformation (distance monitoring, differential settlement, inclination, etc.):

  • Structural and/or site deformation or movement: buildings, bridges, dams, landslips, mines, etc.
  • Tunnel convergence
  • Surface deformation of roads, pavements, rail track, etc.

Principle of operation

schéma de fonctionnement du CYCLOPS de SIXENSE

The CYCLOPS solution gives you:

  • A solution for a multitude of different situations and applications: a standalone or networked system, with or without prism, fixed or mobile, and installed within the zone of influence, but referenced outside of it
  • Sub-millimetric accuracy
  • A system capable of alignment with the phases of complex inspection programmes

CYCLOPS systems are often deployed as part of SIXENSE’s Rail Serenity monitoring solution.
