Galileo E5 Signal Acquisition and Tracking Based On a Wide-band Customized Universal Peripheral N210 Platform

摘要

GNSS navigation has its own advantages which make researchers focus on how to effectively receive and process GNSS signals. This typically needs to utilize flexible specialized radio frequency front-ends, and we need to investigate novel software solutions. Due to the good performance of the Galileo E5 signal, the study of its acquisition, tracking and multipath mitigation has become increasingly significant. This paper has developed a customized 100 MHz wide-band GNSS front-end. Three wide-band datasets of Galileo E5 signal were collected for case study. Final acquisition and tracking results of Galileo E5a signal successfully verified this customized RF front-end usability. It offers great potential for further studying the multi-constellation GNSS compatibility and interoperability to achieve high accuracy and continuity of GNSS navigation.
