Description:
Recently, the Global Navigation Satellite System (GNSS) has experienced problems due to natural and deliberate artificial signal interference. The former is caused by solar activity, where solar flares weaken signals as they travel through the ionosphere, affecting the application of GNSS technology on Earth. Artificial interference, which is highly unpredictable in space and time, poses an additional serious threat to the quality of GNSS applications in positioning, navigation, and timing. Attacks on signals through intentional jamming and/or spoofing negatively impact activities where the use of GNSS is critical for positioning (land-cadaster, civil engineering, spatial planning and geology, navigation, etc.). In addition, GNSS interference poses a serious risk to the security and operation of other critical infrastructures such as telecommunications, electric power networks, banking, maritime and aviation, and protection and rescue systems where GNSS is used also for time synchronization.
Main goals:
The main goal of the project is to create a conceptual model and apply methods to identify intentional interference in the Slovenian CORS (Continuous Operating Reference Station) network SIGNAL. Users will gain insight into interference events and become familiar with procedures to protect GNSS activities. The focus will be on the critical issue of interference with GNSS signals, highlighting the importance of robust mechanisms to identify and detect jamming and/or spoofing. The project will develop methods for detecting interference and assessing positioning quality under problematic intentional interference conditions in the CORS SIGNAL.
