Geodetic COSR GPS/GNSS Infrastructure in Bulgaria—Status and Prospects for Development
摘要
This work presents the construction, development, and status of Bulgarian GPS/GNSS CORS and networks, which are considered a part of the national geodetic infrastructure. We discuss the need for and importance of evaluating the stability of reference stations and the quality of GNSS data for solving scientific and applied tasks. We identify open scientific questions related to expanding the possibilities of applying high-rate GNSS data for advanced research studies. Recent applications of GNSS measurements and their integration with other data to research natural risk processes are briefly outline.
