Abstract
This paper contains the signal receiving algorithm for Galileo E5 AltBOC signal and the development of Galileo E5 signal receiving software. The software runs the process from signal acquisition to extracting measurement data to get navigation solution. It uses logged IF data file as an input. In signal acquisition stage, 1ms and delayed 1ms data are used for reducing correlation ross from secondary code and navigation bit conversion. Signal tracking stage is made of two stages which are coarse tracking and fine tracking. It is for taking advantage of AltBOC characteristic and resolving ambiguity problem due to BOC modulation. The functions of software are verified by signal processing using logged IF data from commercial GNSS simulator.
