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)
