Design of Real-time Processing Platform for Satellite Remote Sensing Data Based on MPI
Liu Li · Spacecraft Engineering · 2013
A platform is designed for high speed and real-time processing of satellite remote sensing data.The platform takes advantage of layered architecture system which,from top to bottom,involves presentation and control layer,business treatment layer,basic service layer,and application support layer.With MPI(message passing interface)technology,a framework is built for distributed real-time parallel processing and demonstrated by aprototype system.The results show that the platform is able to handle double channel data with a download code rate up to 450Mbit/s,and single channel data with processing rate above 6Gbit/s.The platform is applied to the ground test system of remote sensing satellites,and has the advantages of high processing speed and stable operation.
