摘要/Abstract

摘要：

讨论了Galileo系统和GPS系统间不同频率的观测值自由组合的问题。首先分析实现不同卫星定位系统不同频率间观测值的自由组合的意义；其次，介绍国内外对组合观测值问题的研究历程和现状，并指出目前存在的主要问题；然后从理论上证明了Galileo系统和GPS系统间不同频率的观测值组合的可行性；最后得到一些有益的结论和建议。

关键词: Galileo/GPS, 组合观测值, 误差分析, 模糊度求解

Abstract:

This paper discusses different frequency combination observations of Galileo/GPS systems. Firstly, the author analyses the research significance of combination observations in different GNSS. Secondly, the author analyses the present study status of combination observations in internal and external. Thirdly, the author points out the main problems presently. Fourthly, the author proved the feasibility of different frequency observations in different GNSS. Lastly, some valuable conclusions are drawn.

Key words: Galileo/GPS, combination observation, error analysis, ambiguity resolution
