Bingxin YI, Qing Chang, Zhang Qishan

Abstract

This paper presents a comprehensive study of the inter-frequency matchable combinations of 4 Galileo carrier phase observations and GPS L2 carrier phase observation. A comprehensive definition of the combinations of Galileo/ GPS＇s carrier phase observations is given, and errors such as system errors and observation error are analyzed. At last matchable definition and matchable necessary and sufficient conditions of the combinations of Galileo/GPS carrier phase observations are presented.
