Galileo／GPS组合观测值模糊度解算方法研究

Approach to ambiguity resolution using Galileo/GPS combination observations

Galileo和GPS的多个频率可形成有良好特性的组合观测值,利用这些组合观测值可以直接解算载波相位模糊度。本文选用不同波长的Galileo/GPS多频组合观测值,按不同组合方式分步固定整周模糊度,并计算出每步模糊度解算的成功率。本文研究表明,选用合理的观测值组合方式,Galileo/GPS组合观测值模糊度解算方法能以较高的成功率固定组合观测值模糊度及基本载波模糊度。

The muhiple frequencies of Galileo and GPS can form combination observations with good characteristics. Carrier phase ambiguity can be resolved directly with these combination observations. In this paper, Galileo/GPS multi-frequency combination observations with different wavelengths are chosen to resolve ambiguities with several steps. The success-rates are computed at the same time. Studies in this paper show that the success-rates of combination observations and basic carrier waves ambiguity resolution are high enough if reasonable observations are chosen in this Galileo/GPS ambiguity resolution approach.
