Correlation and Tracking Performance of BOC Signal and Approach to Galileo Receiver Design

Galileo system,organized by Europe,is a new generation satellite navigation system which is completely designed for civil purpose.Civil aviation will be one of the application areas that the Galileo system is dedicated to.The Galileo navigation system uses a distinct modulation manner which called BOC(Binary offset carrier) to modulate navigation signal.In order to design a sophisticated Galileo receiver acquisition and tracking channel,a careful study on the auto-correlation performance of BOC signal is required.This article characterizes in brief the Galileo navigation signal and frequency plan,simulates the correlation performance and acquisition and tracking algorithm in terms of BOC signal.Several key issues of receiver design are also discussed.
