摘要
在保持组合模糊度整周特性的前提下,探讨了不同卫星间的相位观测值组合问题,包括系统内和系统间卫星的相位观测值组合。重点研究了GPS与Galileo卫星的相位组合观测值模型,对组合观测值的误差影响进行了详细分析。最后通过大量的计算得出了若干具有良好特性的相位组合观测值,并给出了一种新的组合观测值选取标准。
This paper introduces GPS ＆ Galileo carriers in brief, and then presents a comprehensive study of the inter-frequency combinations of GPS and Galileo carrier phase observations, including satellite observations from the same and other systems. Three main errors of GPS and Galileo combination observations are discussed in detail, and five sets of applied inter-frequency combination observations with typical characters are listed accordingly： wide-lane, narrow-lane, reduced ionic, trop-free and reduced noise combinations. Then some valuable inter-frequency combinations are given by substantial computation, based on which a new combination criterion is given.
