  • To measure total solar irradiance accurately, the solar irradiance absolute radiometer SIAR-3a with the ability of automatic solar tracking is designed and constructed. The principle and structure of the solar irradiance absolute radiometer SIAR-3a are presented in this paper and its control scheme for automatic double-axis solar tracking is proposed. The solar irradiance absolute radiometer SIAR-3a imposes electricity to calibrate the total solar irradiance, which is able to measure the total solar irradiance and follow the sun simultaneously. In the calibration experiments, the corresponding rms error limit of SIAR-3a amounts to 0.06% at the 3 level, which has been calibrated to World Radiometric Reference stored in World Radiation Centre(WRC) in Davos, Switzerland. The experiment results indicate that SIAR-3a works reliably and accurately.
