本文考虑了高斯求和滤波方法在基于载波相位的相对GNSS定位中的应用。双差分载波相位中观测噪声的分布通过高斯分布的加权和来建模，并将Alspach和Sorenson[1]提出的高斯和滤波器进行扩展和修改而导出的高斯和滤波器应用于定位。利用真实的接收机数据进行实验，研究了定位和整数模糊度估计的性能。
In this paper, the applications of the Gaussian sum fil-tering method to the carrier phase based relative GNSS positioning are considered. The distribution of the observation noise in the double differenced carrier phases is modeled by the weighted sum of Gaussian distributions, and the Gaussian sum filter derived by extending and modifying the Gaussian sum filter proposed by Alspach and Sorenson [1] is applied to the positioning. The experiments are done by using real receiver data, and the performance of positioning as well as integer ambiguity estimation are investigated.
