Abstract
Accuracy and intolerance to interference of GNSS receivers depend on the efficiency of tracking modules. To achieve better characteristics, designers should implement various issues, affecting the process of tracking in these modules: integration interval, spacing and configuration parameters of PLL and DLL. The article discusses practical issues concerning implementation of tracking modules. Using the obtained results, it is possible to improve transient characteristics of tracking modules. These issues were tested in an experimental navigation receiver. The results were obtained using the simulation software, developed by the authors, as well as Vivado simulator and experimental testing.
Using the phase of a signal as an informative parameter usually allows for the
highest efficiency of signal isolation from interference and the accuracy of estimating its parameters.
However, in some cases, in particular in conditions of intense interference and fluctuations in signal
parameters caused by the movement...

Simultaneous use of pseudorange, phase and Doppler data from multiple GNSSs for Position, Velocity and Timing (PVT) requires the alignment of the time and frequency scales of the used GNSSs, and additional calibrations, some of them related to the different signal offsets. The accuracy of the PVT solution is also depen...

Global Positioning System (GPS) signals in the L1 band are inherently vulnerable to both intentional and unintentional jamming because of their low received power levels. In this study, the performance of three different adaptive filtering algorithms is investigated against five representative jammer types in a GPS L1...
