Abstract Fast and reliable ambiguity resolution (AR) is the key for high accuracy global navigation satellite system (GNSS) positioning. Due to the different characteristics of GPS and GLONASS in carrier phase frequencies, satellite geometry distribution and observation accuracy, the AR performance of GPS and GLONASS are not identical. This paper presents a GPS/GONASS single epoch AR method for short baseline and the receivers of the same type. Three short baselines are collected using GPS/GLONASS receivers of the same type. The results show that the ambiguity success fixing percentage of GPS is higher than that of GLONASS.
