FY2-03 The Quality Assessment System (QAS)

Background and Contents:

Quality control and assessment plays an important role to the application and popularization of satellite data and product. Domestically, much work has been done on quality and inspection of satellite remote sensing product, and inspection has been conducted in the forming process of the inversion algorithm. The some quality control function has been planted into the generating system of FY-2 satellite products, but independent quality inspection application system has not been set up yet. The QCS of FY - 3 ground application system is in the process of testing and has not been yet officially launched in business operation.

The quality analysis application software of FY2-03 batch data processing center (DPC) is an important part of FY2-03 DPC. The work of DPC includes the whole process of FY2-03 satellite logical data automatic processing: receiving down the broadening data, the extraction of useful information in the data, quantitative product formation, the final distribution to the user. Images and digital products formed by DPC is the main content provided by FY2-03 stationary meteorological satellite ground application system engineering.

The quality analysis application software of FY2-03 batch data processing center (DPC) is composed of three parts, respectively is: DPC preprocessing results analysis (selection, positioning), DPC quantitative analysis on the results (clouds and atmosphere, ocean, land products products) and quality inspection system to support platform.

Overall Framework:
Features and Advantages:

The quality inspection system is one of the main function of the new system installed on FY2-03 stationary meteorological satellite ground application system engineering.

Function of the three aspects:

1) automatic analysis to the primary products, including analysis to location and calibration results, and give out the results of analysis

2) automatic analysis to the secondary products, selection of typical product for quantitative inspection

3) automatic acquisition and management to DPC products, and inspect data needed and scheduler module, automatically generate reports and analysis report, provides the network query
