摘要：
A method of calibration of simulators of the signals of global navigation satellite systems is presented. The effective values of the metrological characteristics of the simulators are determined from the generation of the pseudo-range. The method is based on simultaneous high-frequency analog-to-digital conversion of the navigation signal and the second mark of the time scale of the signal simulator with subsequent digital demodulation, filtration, search for a transition of the corresponding front of the binary modulating sequence through zero, and measurement of the time interval between the phase transition and time stamp of the simulator scale. It is proposed that sampling and recording of the high-frequency signal of the simulator and its second mark be performed in the same time scale with subsequent demodulation of the recorded signal into quadrature components.
