The solar irradiance monitor (SIM)
with the design accuracy of 5
used to monitor the secular changes of the total solar irradiance on FY-3 satellite
takes the sun-scanning measurement method on-orbit. Compared to the sun-tracking measurement method
this method simplifies the structure and cuts the cost
but the measuring accuracy is affected by the sun-synchronous orbit
sunlight incidence angle and the installing angle of the SIM in the satellite. Through the ground calibration experiment
studies on the affection of different sunlight incidence angles to the measurement accuracy. First
by the satellite tool kit (STK) simulation software
simulates the orbital parameters of the sun-synchronous satellite
and calculates the Sun ascension and declination at any time. By the orbit coordinate transformation matrix gets the components of the Sun vectors to the axes of the satellite
and base on the components designs the field of view and the installing angles of the SIM. Then
designs and completes the calibration experiment to calibrate the affection of the incidence angles. Selecting 11 different angles between the sunlight and the satellite X-axis
measures the total solar irradiance by the SIM at each angle
and compares to the irradiances of the SIAR reference radiometers
and gets the coefficient curves of the three channels of the SIM. Finally
by the quadratic fitting
gets the correction equations on the incidence angles: R 1=5.7110-52 -2.45310 -3+1.0302
R2=2.8410-5-1. 96510-3+1.0314 and R3 =1.7210 -52-4.18410-4+0.9946. The equations will aimprove the on-orbit measurement accuracy of the solar irradiance
and are very important to the on-orbit data processing after the satellite launched. 2011 SPIE.
