A survey of techniques and algorithms in deformation monitoring applications and the use of the Locata technology for such applications

24/7 deformation monitoring of manmade structures is a challenging research issue due to high labour cost or dependency on favourable geometry (in the case of GPS/GNSS). Locata, working on similar principles to carrier phase-based GPS, is a possible technology for use in deformation monitoring applications by providing millimetre level precision and centimetre level accuracy. This paper reviews current techniques and algorithms used in “slow” structural deformation monitoring applications and the potential use of Locata technology within a Locata Deformation Monitoring Software (LDMS). A simulated deformation experiment has been conducted for the verification and validation of LDMS.
