 Global Navigation Satellite System Technologies and Applications

Global navigation satellite systems (GNSS) are primary systems for measuring position and time. Besides classical applications as intelligent transport systems, today the GNSS technologies are used also in many other industrial and scientific applications. For example, since GNSS satellites can be considered as passive sources of radiation, GNSS signals can be used also for remote sensing applications, which consist in the processing of GNSS signals reflected back from the ground. The discipline of GNSS-Reflectrometry (GNSS-R) deals with techniques of remote sensing of land and ocean surfaces, but other applications are emerging such as winds retrieval, altimetry, soil moisture sensing, ice monitoring, water level and snow thickness measurements. GNSS-R is only an example of physical quantities measured with the support of GNSS, and other applications are fast emerging. On the other hand, the management of the GNSS asks for a continuous series of measures, on board and on ground, and fast processing to be able to monitor and control the behavior of all the systems segments. On board for example many sensors are active (temperature, radiation, attitude,..), clocks and different stages of the signal generation are measured and from ground corrected. This special session aims to promote the advancement of measurement and instrumentation used for the GNSS improvement and for the different applications based on GNSS. As such, this session aims to bring together researchers working on the various facets of GNSS technologies and applications, in all areas of instrumentation and sensing where GNSS signals play a significant role.
