Estimation of multi-constellation GNSS observation stochastic properties using single receiver single satellite data validation method

摘要: The single receiver satellite validation method is a technique that screens data from each independently to detect and identify faulty observations. A new for estimation of the stochastic properties multi-constellation GNSS observation presented utilising parameters this method. Agreement characteristics statistics with theory used as criterion select best precision observations, spectral density correlation time unknowns. curve fitting approach in an iterative scheme employed. applicable any arbitrary number frequencies. Demonstration results performance given using multiple-frequency GPS, GLONASS Galileo static kinematic modes.
