摘要
简要介绍了Galileo系统 ,然后在模糊度保持为整数的前提下 ,论述了由Galileo系统的四个频率载波进行测量的组合观测值的一般定义 ,并对有关的误差影响进行了分析 ,最后根据一定的组合标准讨论了具有特定性能的组合观测值 ,并给出了一些典型的组合 。
This paper introduces Galileo system in brief, then presents a comprehensive study of the inter-frequency combinations of 4 Galileo carrier phase observations. This paper discusses some error impacts of Galileo combination observations, expatiates the method for defining the ranges of searching combination coefficients in detail, and accordingly lists two sets of applied inter-frequency combination observations with typical characters: widelane combinations and reduced-iono combinations. As a result, some valuable inter-frequency combinations are found.
