摘　　要： 针对短基线详细研究GPS/GLONASS组合定位函数模型,引入一种简单易行的模糊度求解方法以正确固定GLONASS模糊度,最后笔者自编软件实现基于相位差分的GPS/GLONASS高精度组合定位,并采用实际数据验证其正确性和有效性。结果表明:GPS/GLONASS组合系统优于单系统,采用相位观测值可获得高精度定位结果。 The paper detailedly investigated the functional model of GPS/GLONASS for short baselines.Then a simple and practiced method for GLONASS ambiguity resolution was introduced.Finally,the GPS/GLONASS integration positioning program was realized with MATLAB language and its efficiency was validated with real data.The result shows that GPS/GLONASS integration system is superior to single system and can achieve the high accuracy of positioning with carrier-phase measurement.
