  • Hardware signal simulator can be used to calibrate the hardware delay of the ionospheric TEC monitor. In this paper, the long-term change of DCB derived by hardware calibration method is analyzed, by two independent calibration experiments (with a time interval of nearly 41.5 months) on the same receiver (for GPS signals). The results show that the mean DCB value of the receiver increases from 16.122ns in the first experiment to 16.749ns in the second experiment. It increases 0.627ns in about 41.5 months. The monthly increment of DCB is about 0.0151ns. The standard deviation of DCB increases slightly from 0.05ns to 0.07ns between the two experiments. In addition, the TEC calibration accuracy (Root Mean Square Error) of both two experiments reach about 0.3TECU, and the corresponding DCB errors reach about 0.1ns. It indicates that the DCB variation between different channels is quite consistent. In the second experiment, the TEC measurement error will increase to about 1.8TECU if using the DCB value obtained in the first experiment. The monthly increment of TEC error is about 0.0434TECU.
