    Abstract
  • Since International Global Navigation Satellite System Service (IGS) started Multi-GNSS Experiment (MGEX) in 2011, multi-GNSS compatibility and interoperability have become a research hotspot. International GNSS Monitoring and Assessment System (iGMAS) were initiated for the first time in order to monitor and evaluate the running status and performance indicators of GNSS. In view of this, starting from the users, this paper makes quantitative analysis on the data integrity rate, cycle ratio, pseudorange multipath, carrier to noise ratio (CNR), pseudorange measurement accuracy of continuously operating reference station (CORS) data, and discusses the method of monitoring and evaluation of the BeiDou data quality in the range area based on the range CORS, so as to provide a scientific and quantifiable satellite environmental accuracy index for high-precision weapon test.
