TLDR
In this article, a characterization of the behavior of phase tracking loops in the presence of severe equatorial ionospheric scintillation is given, and a differentially detected bit error model is proposed to predict cycle slipping rates.Abstract:
A characterization is given for the behavior of Global Positioning System phase tracking loops in the presence of severe equatorial ionospheric scintillation. The purpose of this work is to develop a simple, general, and realistic scintillation effects model that can be used to improve the scintillation performance of phase tracking loops. The new characterization of scintillation effects proposed herein employs a differentially detected bit error model to predict cycle slipping rates that approximately agree with data-driven simulation tests.read more

Simulating Ionosphere-Induced Scintillation for Testing GPS Receiver Phase Tracking Loops
TL;DR: Hardware-in-the-loop tests show how the model can be used to test the scintillation robustness of any compatible GPS receiver and the model validated, by comparison with phase-screen-generated and empirical scintillation data in realistic tracking loop tests.

Data-Driven Testbed for Evaluating GPS Carrier Tracking Loops in Ionospheric Scintillation
TL;DR: Testbed results indicate that cycle slips are primarily caused by the abrupt, near half-cycle phase changes that occur during the deep power fades of severe equatorial scintillation.
