The study is devoted to the uses of laser scanning in the field of engineering surveying. It is currently one of the main trends of research which is developed at the Department of Engineering Surveying and Civil Engineering at the Faculty of Mining Surveying and Environmental
Robotic total stations are a group of surveying instruments that can be used to measure moving prisms. These devices can generate significant errors during kinematic surveys. This is due to the different speeds of the total station’s measurement subsystems, which results in the observations of the point location being performed in different places of the space. Total stations which are several years old may generate errors of up to a few dozen centimeters. More modern designs, with much lower delays of the mechanical and electronic subsystems, theoretically allow to significantly reduce the values of the errors. This study involved the performance of kinematic tests on the modern robotic total station Leica MS50 in order to determine the values of measurement errors, and also to define the possibility of using them for the above-mentioned applications.
Static satellite surveying techniques are commonly used for the geodetic monitoring of mining areas, especially to determine horizontal coordinates of points. Satellite surveys are currently being connected to permanently established reference stations. In many countries, two or more reference networks work independently. In Poland, there are four nationwide networks of reference stations and one regional network. All commercial networks must be tied to the national network ASG-EUPOS. This research paper has analysed the influence of tying the points used for mining area monitoring purposes to various reference networks on their adjusted coordinates. The author has attempted to process the results of these satellite surveys at the engineering level, most frequently encountered in the field of surveying. The computation has been carried out using commercial software. Static observations from four reference networks operating in Poland have been used to compute the coordinates of the test points: ASG-EUPOS. NadowskiNET. TPINetPRO and VRSNet.pl. Leica Geosystems Polska has not provided access to its static satellite observations for testing purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
