Design of Aerospace Data Parallel Pre-processing Ground System Based Grid Workflow

Aerospace data pre-processing ground system play an important role in aerospace exploiting. Today, there're several special aerospace data pm-processing ground system in operation. As experimental activities of space exploration continue to carry out, payload types is increasing, data types and the satellite downlink data are growing on a large scale. For multi-tasks and multi-payloads aerospace massive data processing, this article analyses and designs a aerospace data parallel, pre-processing ground system with grid workflow scheduling. It can be used to create appropriate processes flexibility and quickly, adjusting the data pre-processing of multi-missions and multi-payload[2]. Addition, it has perfect scalability in business and computing ability. So, it can meet the future requirements of aerospace data pre-processing.
