A Compact Strong-scatter Scintillation Model

This document describes numerical solutions to the 4-order moment equation for scintillation under strong scatter conditions. It is well known that scintillation depends on the parameters that describe the structure size distribution, and the Fresnel radius. However, in an unconstrained fixed power-law environment, the theory can be formulated in terms of a single parameter. In effect, differen...

GNSS Multifrequency receivers in urban environment: Theoretical analysis

In this paper, a theoretical approach for the analysis of synchronization performances in GNSS receivers adapted to reduce errors, especially caused by multipath fading, in a urban environment is proposed. In particular, two kinds of bi-frequency receivers based on data fusion methods are analyzed. The performances have been evaluated by comparison of simulated results in a real case and theore...

Study of GNSS Loss of Lock Characteristics under Ionosphere Scintillation with GNSS Data at Weipa (Australia) During Solar Maximum Phase

One of the adverse impacts of scintillation on GNSS signals is the loss of lock status, which can lead to GNSS geometry and visibility reductions that compromise the accuracy and integrity of navigation performance. In this paper the loss of lock based on ionosphere scintillation in this solar maximum phase has been well investigated with respect to both temporal and spatial behaviors, based on...
