中文摘要：
应用适合于处理由相同类型接收机组成的短基线的模糊度固定方法,采用实测数据计算分析GPS与GLONASS单历元双差模糊度的固定效果。结果表明,GPS单历元双差模糊度成功固定的比例略高于GLONASS。
英文摘要：
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.
