Abstract

The monitoring of important engineering buildings is mandatory and necessary especially in crowded urban areas. Achieving a stable and optimal monitoring network leads to a more effective time monitoring of objectives through the use of satellite methods. Satellite geodetic technology along with emerging technologies is a modern way to get data on civil buildings monitored with reasonable accuracy. Thus, the fast evolution of communication technologies allowed and developed several satellite constellations throughout the Globe at the same time, depending on the needs and economic power of owners. In the present scientific paper, we will describe an analysis of the accuracy of data obtained with the use of satellite technology for monitoring the behavior of an engineering building using Romanian Positioning System (ROMPOS) based on satellite systems such as: Global Navigation Satellite System (GNSS), Russian GLONASS and European Galileo, but also on GNSS permanent stations, obtaining real-time data in the ETRS89 European Coordinate System. The aim of this paper is to compare the use of the Global Positioning System (GPS) and GLObalnaya NAvigatsionnay Sputnikovaya Sistema- GLONASS, Chinese Navigation Satellite System – BeiDou, both individually and simultaneously to determine the control points of the monitoring network. The precision of station points determining for an engineering structure is important, and in the case of the use of satellite technology it can be influenced by multiple factors that will be presented in the paper. The accuracy of the station coordinates of the selected target is given by integrating both satellite constellations by increasing the number of satellites used, obtaining a more accurate position with greater visibility to them. It is an engineering structure, viaduct type, over 50 years old, with a length of 1.3 kilometers. The objective is in the North-West part of Galati, Romania and represents an important access road connecting Galati city to the platform of ArcelorMittal steel company requiring a regular observationeven a permanent monitoring.
