Test of Vibrations Influence on the Measurement Accuracy in the Precise Digital Leveller Trimble Dini 03 and Comparison of Its Vibration Sensitivity with Leveller Ni 002

Abstract

The article presents findings from research on the effect of vibrations on the accuracy of measurement with an automatic precise digital leveller. A special research station was created to induce vibrations on a leveller and to measure vibration parameters that affect staff reading. It contains description of discovered relationship between the vibration parameters and the mean error of a single height difference measurement. The range of frequencies for which the measurement was possible was estimated. The reliability of the measured values obtained under specific vibration conditions was also analysed. The results of current research were compared with similar studies on analogue leveller Ni 002. The conclusions described in this paper can be helpful in engineering measurements under adverse conditions of ambient vibrations.

Experimental Research of the Structure Condition Using Geodetic Methods and Crackmeter

“…Modern measuring technologies enable the implementation of tasks that have not been possible until now by traditional methods while ensuring the required precision. Currently, construction objects and subsoil can be monitored using classic geodetic methods [14,15], the GNSS system and gravimetric measurements [16][17][18], unmanned aerial vehicles, and laser scanning [19][20][21], and supplemented with GIS technology [22,23]. The analytical part of the displacement determination process and the prediction of changes and planning of modernization work on the facilities can also be supported by intelligent monitoring systems based on artificial intelligence [24][25][26][27].…”

Accuracy Characteristics of the Selected Diagnostics Methods and the Adjustment of Geodetic Observations

“…Classic geodetic networks (horizontal and vertical) are the basic scheme for geodetic measurements and their use in engineering and research. Geodetic networks are used as an essential tool for obtaining information for monitoring displacements and deformations of building objects [1,7,12,20,32], in geodetic planning, and agricultural management works [13,23], in spatial and geographic information systems [18,23,33], in engineering geodesy [5,9,10,17,24] or photogrammetry and remote sensing [2,3,25,29,30]. It is essential to determine the coordinates of geodetic networks characterized by a high level of confidence and with identified mean errors considering the wide application of geodetic measurements in various fields of knowledge.…”
