This study presents a novel solution of DLL discrimination function for multiband global navigation satellite systems (GNSS) receivers, designed to cope with a multipath-prone environment in safety-of-life (SoL) applications. The solution is based on a combination of squared correlators (CSC) outputs, following an approach similar to that driving to the well-known, and patented, Strobe discriminator...
Due to the large amount of different new applications based on GNSS systems, the issue of interference monitoring is becoming an increasing concern in the satellite navigation community. Threats for GNSS can be classified as unintentional interference, jamming and spoofing. Among them, spoofing is more deceitful because the target receiver might not be able to detect the attack and consequently generate...
Services based on Global Navigation Satellite Systems (GNSS) are currently in use in many critical networked infrastructures and crucial applications. Within the described scenario, the importance for the GNSS community of investigating the effects of spoofing attacks, together with anti-spoofing techniques, appears essential. This paper describes the results of preliminary tests performed in lab...
A constantly increasing number of new applications are based on wireless communication system integrated with navigation/positioning platforms. The mutual benefits they can obtain from each others are intrinsically related to the interoperability level and to a properly designed coexistence. In this paper a new family of curves, called interference error envelope (IEE), is used to assess the impact...
The function of the front-end of a global navigation satellite system (GNSS) receiver can be roughly described as the provision of received signal samples at intermediate frequency (IF) to the base band section. Due to the low power of the received signal, several phenomena might threat the correct operation of the front-end, and consequently degrade the performance of the acquisition and tracking...
