Impact of GNSS receiver tuning on the estimation of scintillation index

Résumé

When crossing the ionosphere layer, GNSS signals may be impacted by scintillation, a dynamic effect which causes very fast variations of the amplitude and the phase. The GNSS receivers may lose lock, which lead to unavailability of the satellite link as well as the reduced reliability of the available information. In the present state of the art, the understanding of scintillation phenomena is still insufficient, and the available models are still not adequate for GNSS system design. Thus, many studies are carried out in order to model scintillation [1] [2] [3] and evaluate the effect on the GNSS receivers and augmentation system [4] [5]. These studies monitor the scintillation thanks to specific scintillation index. However, the estimation of these scintillation indices may be affected by the receiver itself and by the estimator. The goal of this paper is to understand how receiver or estimator tuning may impact the estimation of scintillation index. To conclude, this paper gives recommendation on how to tune GNSS receiver or estimator in order to minimize their impact.
