The ionosphere has been the most challenging source of error to mitigate within the
community of global navigation satellite system (GNSS)-based safety-critical systems. Users …

In most wired and wireless systems, carrier tracking is an essential task that allows the
receiver to precisely synchronize with the carrier of the incoming signal. Stringent carrier …

This paper investigates three different Kalman filter implementation options to estimate
signal tracking errors in a GPS receiver with particular emphasis given to the carrier phase …

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 …

In this paper we discuss several different Kalman filter methods to estimate signal
parameters in a GNSS receiver's signal tracking loop with a special emphasis given on how …

The performance of several GPS carrier tracking loops is evaluated using wideband GPS
data recorded during strong ionospheric scintillations. The aim of this study is to determine …

Abstract Global Positioning System (GPS) receiver positioning capabilities are being
challenged by increasing requirements on positioning and navigation under environments …

This paper describes a GNSS software receiver architecture and the associated benefits in
terms of algorithm flexibility and processing efficiency. For the latter, different signal …
