摘要：

【目的】随着我国北斗卫星导航系统（BeiDou System,以下称BDS）的建设完成,GNSS（Global Navigation Satellite System）导航系统呈现以BDS、GPS、GLONASS及Galileo为主的多频多模并存的格局,多系统融合定位数据处理成为近年来GNSS发展的趋势,得到了广泛而深入的研究。【方法】本文对近10年来多频多模GNSS融合数据处理中BDS观测信息的质量评估、观测随机模型的构建、融合定位方法、系统间偏差（Inter-System Bias, ISB）处理等方面的研究进展进行了归纳。【结果】对近年来的相关研究成果进行梳理,便于该领域的研究人员更好了解多频多模GNSS融合处理的发展现状,为GNSS数据融合处理研究方向提供参考。

Abstract:

[Objective] With the finished construction of the BeiDou navigation system (BDS) in China, GNSS appears a co-existence pattern with multi-frequency and multi-mode which mainly include BDS, GPS, GLONASS, and Galileo. The data processing integrated multi-system positioning has become the trend of GNSS development in recent years and has been widely investigated. [Methods] This paper summarizes the GNSS research progress in recent 10 years, mainly on quality evaluation of BDS observations, stochastic model construction, integrated positioning methods, inter-system bias (ISB) processing, etc. [Results] The purpose of this paper is to introduce the research achievements of the GNSS fusion positioning in recent years, so the current status and the research directions in this field can be understood and referenced by the researchers.

Key words: GNSS with multi-frequency and multi-mode, integrated processing with BDS/GNSS, quality evaluation of BDS observations, inter-system bias (ISB)
