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 re”
