Abstract: There is a variant of test equipment building for GNSS receivers, which are being contained in autonomous navigation system of space vehicles. Software of navigation signal simulator of simultaneously four GNSS (GLONASS, GPS, Galileo and BDS) has been developed. Vector signal generator is used as hardware. By means of real-time radiofrequency oscilloscope and special software for navigation signal analysis, accuracy research of signal delay changing law reproducing has been performed.
Keywords: test equipment, autonomous navigation system, space vehicle, global navigation satellite system (gnss), signal simulator, signal analyzer, mean-square error
