Study for the Matchable Combinations of Galileo/GPS Carrier Phase Observations
-
摘要: 详细讨论了Galileo系统的4种载波与GPS L2载波的相位组合观测值的可匹配问题.在模糊度保持为整数的前提下,给出了Galileo/GPS载波相位组合观测值的定义,并对包括系统噪声和观测噪声在内的有关误差影响加以分析,最后给出了组合观测值可匹配的定义和判断可匹配的充要条件.Abstract: This paper presents a comprehensive study of the inter-frequency matchable combinations of 4 Galileo carrier phase observations and GPS L2 carrier phase observation. A comprehensive definition of the combinations of Galileo/ GPS's carrier phase observations is given, and errors such as system errors and observation error are analyzed. At last matchable definition and matchable necessary and sufficient conditions of the combinations of Galileo/GPS carrier phase observations are presented.
