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.

In current field of CCD measurement
large area and high resolution CCD is used to obtain big measurement image
so that
speed and capacity of CCD requires high performance of later storage and process system. The paper discusses how to use SCSI hard disk to construct storage system and use DSPs and FPGA to realize image compression. As for storage subsystem
Because CCD is divided into multiplex output
SCSI array is used in RAID0 way. The storage system is composed of high speed buffer
DMA controller
control MCU
SCSI protocol controller and SCSI hard disk. As for compression subsystem
according to requirement of communication and monitor system
the output is fixed resolution image and analog PAL signal. The compression means is JPEG2000 standard
in which
9/7 wavelets in lifting format is used. 2 DSPs and FPGA are used to compose parallel compression system. The system is composed of FPGA pre-processing module
DSP compression module
video decoder module
data buffer module and communication module. Firstly
discrete wavelet transform and quantization is realized in FPGA. Secondly
entropy coding and stream adaption is realized in DSPs. Last
analog PAL signal is output by Video decoder. Data buffer is realized in synchronous dual-port RAM and state of subsystem is transfer to controller. Through subjective and objective evaluation
the storage and compression system satisfies the requirement of system. 2009 SPIE.

STIM (Solar Total Irradiance Monitor) can be used on sun-synchronous polar orbit weather satellites to measure the total solar irradiance. It contains three independent and identical wide view absolute radiometers. They are mounted on the satellite in an angle which ensure the sun scan over the field of view of the absolute radiometers. This measurement method doesn't need the instrument tracking the sun but the sun scan over the field of view of the absolute radiometers in each orbit cycle. The paper presents the measurement method of simulation for solar irradiance measurement and calibration by mounting the instrument on a two-axis rotation table. By controlling the rotation angle velocity of the instrument in the meridian direction being the same as that of the weather satellite's on orbit
we can measure the solar irradiance when the sun scan over the field of view of the absolute radiometers to simulate the onboard state. And we have operated the measurement with the prototype of STIM. The SIAR-1 is traceable to WRR and serves as a transfer standard. So simultaneous comparison measurements between SIAR-1 and each of the three wide view absolute radiometers are measured to provide calibration corrections to the instrument. And we have a further study at the influence of stray light to the measurement results. This paper presents the method of simulation experiment and calibration for solar irradiance measurement with Solar Total Irradiance Monitor on board.

The conical black cavities are used in the Solar Irradiance Absolute Radiometers (SIARs) of the solar constant monitor aboard on the SZ spaceship and of the Solar Total Irradiance Monitor (STIM) aboard on sun-synchronous polar orbit weather satellites. A low reflectance measurement instrument which is used for making the integrating measurement on the reflectance of the conical black cavity in a high precision within the full hemisphere (include the entrance of the Ulbrichtsphere) has been constructed. The characteristic of the instrument is the employment of a semi-transparent mirror
which is mounted in an inclination angle of 45 degrees in front of the entrance of the Ulbrichtsphere. The incident beam is reflected to the black cavity or white board by the semi-transparent mirror. A portion of those
which is made diffused reflection through the black cavity or white board
is measured by the detector located in the side face of the Ulbrichtsphere
and the other portion which is reflected to the entrance is measured by the other detector
after passing through the semi-transparent mirror
and then being focused on by an ellipsoidal mirror. The two measurement data are added up to get the integrating reflectance within full hemisphere. The presentation and verification on the measurement result of the reflectance of the black cavity and its precision are described in this article. The absolute accuracy can reach 0.012%.
