Monitoring of mining areas in relation to various reference networks

Abstract

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.
