SOME PRACTICAL ISSUES OF THE TRACKING PROCESS IN GNSS RECEIVERS

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.
