Integrated system able to measure errors of satellite navigation system receivers

The report discusses the methodology of physical integration and characteristics of an integrated inertial satellite navigation system (ISNS). The report shows benefits of the physical integration method as compared with the traditional method of mathematical integration based on Kalman filter. Mathematical modelling, laboratory and flight tests allowed to state that ISNS is able to measure and remove the effect of systematic errors of GPS/GLONASS receivers on the accuracy of the integrated channel of navigation. The report presents results of the flight experiment for the measurement of errors of four types of GPS/GLONASS receivers.
