Galileo E5 AltBOC Signals: Application for Single-Frequency Total Electron Content Estimations

Code Phase Multipath Mitigation by Exploiting the Frequency Diversity in Galileo E5 AltBOC

In heavy multipath scenarios such as urban canyons, the user code phase pseudorange error due to multipath fading can be as high as two meters even for the most sophisticated ranging signals such as Galileo E5 Alternate Binary-Offset-Carrier AltBOC (15,10). In this paper the author introduces methods to mitigate the code phase multipath by exploiting the frequency diversity which is inherent to...

Economic Galileo E5 Receiver

The Galileo system introduces an extremely wideband civil E5 signal for high precision navigation. The structure of the receiver for the E5 signal is complicated due to the signal complexity and the large bandwidth. It is possible to process the whole E5 signal or process separately E5a and E5b parts combining obtained results afterwards (we call here such method as piece-wise processing). The ...

An Innovative Data Demodulation Technique for Galileo AltBOC Receivers

This paper describes an innovative solution that can be used to recover the navigation data from Alternative Binary Offset Carrier (AltBOC) modulated signals, a modulation scheme foreseen for the Galileo satellite navigation system to transmit four channels in the E5 band (1164-1215 MHz). In this paper a novel data demodulation approach, called Side-Band Translator (SBT), suitable to coherent d...

Hybrid Tracking Loop Architectures for the Galileo E5 Signal

Due to their structure, Galileo E5 signals offer a number of ways to synchronise the signal and to demodulate the data. In this paper the authors describe the architectures required, and discuss the pros and cons of several of these methods, for tracking the E5 signal. It is shown that the trade-offs in tracking individual components of the E5 signal can be converted to advantages thereby impro...
