Investigating the practicability of periodically collected tusaga-active measurement in deformation monitoring

Controlling of engineering structures and determining horizontal and vertical crustal movements are of great importance today. The deformation analyses of structure control and determining crustal movements have constantly been one of the basic subjects of geodesy. Shape, dimension and displacement of the objects are determined and interpreted through these analyses.TUSAGA-Active named as Ağ-RTK in Turkey provides real-time precise coordinates for the users all around Turkey. This study investigates the practicability of real-time TUSAGA-Active data collected periodically in deformation monitoring. The aim of this study is to analyze the usefulness of TUSAGA-Active measurements in deformation monitoring collected periodically in a certain point through TUSAGA-Active method being one of the accepted methods in numerous fields and so make relatively more realistic interpretations. For this purpose, 10-epoch TUSAGA-Active measurements were made every three months periodically in a certain point in Gumushane University campus with GNSS receivers using TUSAGA-Active data. The measurements were adjusted and statical and kinematical deformation analyses were carried out. Then the results were compared and it was observed that they were compatible.This method is more practical and economical than the others. Only one person and a GNSS receiver are needed in order to make deformation measurements and analyses. Measurements take a very short time. In addition, a large number of data can be collected in the application area in a very short time. However, the accuracy of the method is at the centimeter (cm) level.Key Words: TUSAGA-Active, Network-RTK, Deformation, Adjustment, Statical Analysis, Kinematical Analysis
