Abstract

Based on the analysis for Galileo unique features, this article attempts to outline the specific benefits that the Combined Galileo and GPSconstellations can bring to users, including some implications that can be expected when Galileo and a modernized GPS are fully operational. The article presents the author’s personal observations and visions for Combined Galileo and GPStechniques, expecting comments from experts in the field, service providers and users.
