This article uses a receiver to analyze the data quality of the carrier to noise ratio of the simulator in five states:normal state,ionosphere on,troposphere on,multipath simulation function on,and 20dB power gain on.The simulated satellite signals are also collected and broadcasted using a GNSS acquisition and playback instrument for carrier to noise ratio analysis.Through experimental analysis,it has been shown that playing simulator signals through the playback device does not affect the quality of GNSS signal data.During the calibration process of the receiver,it is possible to improve calibration efficiency by collecting simulator signals from the playback device.
