Toward an integrated Data Quality Analysis and Assessment System for HJ satellite constellation
The small satellite constellation for environment protection and disaster monitoring (HJ satellite constellation) is facilitated to satisfy the country and surrounding countries or regions need of dynamic monitoring and forecasting environment and disaster through the use of remote sensing.HJ-1A and HJ-1B will be launched in 2008 and the ground system of which is being developed in accordance with the technical demands of their owners.The quality of data acquired by onboard sensors is essential to effective application of the data,which is also a measure of the success of the engineering and science efforts of operational satellite program.To systematically monitor and measure the sensors in flight performance and data quality,we designed an integrated Data Quality Analysis and Assessment System (DQAAS) for HJ satellite constellations ground system,and are developing a demonstrating DQAAS system,which is also a part work of Sky-To-Earth System of Systems (STESS).This paper first analyzes the necessities to include a Data Quality Analysis and Assessment System in the ground system of HJ satellite constellation.Upon the analysis of the function requirements of DQAAS,the framework and structure of DQAAS is presented.The operation flow and interfaces definition is very important for an integrated system,which is also included in the paper.At last,the functions and algorithms of Data Quality Assessment Subsystem are introduced in detail.We expect to promote the quality and analysis and assessment technology in China through the development of DQAAS for HJ satellite constellation.
