In most wired and wireless systems, carrier tracking is an essential task that allows the
receiver to precisely synchronize with the carrier of the incoming signal. Stringent carrier …

It is known that satellite radiolocalization was born in the military environment and was
originally conceived for defense purposes. Nevertheless, the commercial explosion (dated …

This paper presents a generalized theoretical framework for carrier tracking of global
navigation satellite systems signals by constructing a state space representation for the …

Characteristics of signal tracking Kalman filter (KF) approaches for a Global Navigation
Satellite System (GNSS) receiver are presented. In particular the direct-state KF is designed …

This paper presents the performance analysis and the optimizations of the generalized
phase locked loop (PLL) and the generalized frequency locked loop (FLL). Using the …

Fundamental results in the literature showed that a class of Kalman filters (KF) converges to
a digital phase lock loop (DPLL) structure. Results were proved for second-and third-order …

Strong ionospheric electron content gradients may lead to fast and unpredictable
fluctuations in the phase and amplitude of the signals from Global Navigation Satellite …

Abstract The former Galileo Commercial Service (CS) will provide a High Accuracy Service
(HAS) and a Commercial Authentication Service (CAS). The first will disseminate free …

High-precision GNSS positioning plays a crucial role in intelligent transportation systems,
and leveraging artificial intelligence can enable the development of reliable context-aware …

Global Navigation Satellite Systems (GNSS)-based position service is widely applied in
cities, but the precision varies significantly in different obstruction scenes. Scene recognition …
