Abstract
With the rapid development of multi-constellation global navigation satellite systems (GNSS), the world of satellite navigation has undergone tremendous changes. Once all six systems (IRNSS, BeiDou, QZSS, Galileo, GLONASS, and GPS) are deployed in the next few years, approximately 150 satellites will be available, which will bring huge opportunities and challenges to science and engineering applications. This paper describes an experiment conducted with the static method for the Multi-GNSS about achievable accuracy especially for the long baselines (Wide Lane ambiguity solution). The obtained results indicate that integrating GPS systems with Galileo, GLONASS, BeiDou, QZSS and IRNSS are favoured for surveying applications. It appears that through the integration of GPS/GLONASS/Galileo/BeiDou/QZSS/IRNSS static measurements in the study area, millimetre-centimetre accuracy may be guaranteed on for long baselines by using Wide Lane (WL).
