在介绍Galileo系统空间信号的基础上,以模糊度保持整数为前提,在前人的基础上给出了Galileo系统的四个频率载波与GPS L2载波的组合相位观测值的定义,分析了组合观测值的误差传播规律.最后根据一定的组合标准论述了具有相应特性的组合观测值,并给出一些典型的组合.

Based on the introduction of space signals in Galileo system and under the condition that the ambiguity was kept as integers, the combination of the Galileo and GPS carrier phase observations was defined. The error propagation law of the combined observations of carrier phase was given, and the method for defining the ranges of searching combination coefficients was expatiated in detail. Accordingly two sets with typical characters such as widelane combinations and reduced-iono combination were listed. As a result, some valuable inter-frequency combinations were found.
