Abstract
Global Navigation Satellite System (GNSS) technology is growing fast in our society and new applications are being introduced at an unprecedented pace. The GNSS products provide worldwide and real-time services using precise timing information, positioning and synchronization technologies. Within years, GNSS applications are becoming more accurate and their precision opens doors to a wide range of applications. Nevertheless, these applications are susceptible to disruption in the operation of GNSS receivers when malfunctions, failures or interference occur. This paper’s objective is to make an overall analysis of GNSS failure impact on society and therefore make a review of GNSS spectrum protection strategies. In the first three sections of this analysis, we survey GNSS applications, their importance and their criticality. While questioning the criticality of GNSS applications, we evaluate their impact on main critical infrastructures and particularly the risks of critical dependencies in case of failure or interference. In the last two sections, we investigate GNSS spectrum interference in relation to its effects on crucial infrastructures. We review the principal Radio Frequency Interference (RFI) sources leading to GNSS and satellite communications (SATCOM) spectrum issues. Alongside, we study various ways to mitigate RFI. This process is essential to further develop and standardize mitigation techniques and to ensure GNSS spectrum immunity against RFI.

Summary
The goal of this paper is to investigate the importance of GNSS civilian applications in our society. The acronym GNSS (Global Navigation Satellite Systems) is nowadays a common term used to point out current and future satellite-based navigation systems. While some systems (US-built GPS and the Russian GLONASS) are fully operational, others systems are still in development (European Galileo and Chinese Compass/BeiDou). These global navigation systems are backfilled with regional navigation systems (Indian IRNSS and Japanese QZSS) and augmentation systems like US WAAS, European EGNOS, Japanese MSAS and Indian GAGAN. GNSS receivers are integrated in numerous applications and they are increasingly forming part of human habits. They provide a strong impact for countries development. GNSS applications are linked with all levels of human security in our society
