摘要
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,给出了Galileo系统的4个频率载波与GPS L2载波的组合相位观测值的定义,并对有关误差影响加以分析,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 introducing signals in space of Galileo system and under the condition that the ambiguity is kept as integers, this paper defines the phase combination observations of the 4 Galileo and GPS L2 carriers. The relevant error impact is analyzed and the method for defining the ranges of searching combination coefficients is expatiated. Accordingly two sets of applied interfrequency combination observations with typical characters are also listed. Finally, some valuable inter-frequency combinations are given.
