摘　　要：从基本的载波相位观测模型出发,得出了三频线性组合的一般形式。通过分析电离层延迟和观测噪声对三频组合的影响,给出了选择线性组合系数的长波长标准、弱电离层延迟标准、弱随机噪声标准。并依此为标准,给出了一些组合性质较好的线性组合。A general form of triple frequency Carrier Phase combination deduced from the basic GPS carrier phase observation model is present.Then,the influences caused by ionosphere errors and observation errors are analysed.There are three criteria that can be examined,the greater wavelength,the ionospheric impact,the noise.Finally,some linear combinations are given based on above criteria,and their advantages and disadvantages are also analysed.
