SATELLITE DATA DECOMPRESSION SYSTEM

摘要

The present invention relates to a system for decompressing satellite data comprising a data distribution unit, a plurality of decompressing devices, and an operation system. The data distribution unit outputs compression data transmitted from a satellite by performing the compression data in a distribution parallel process. The plurality of decompressing devices receives compression image data of the data distribution unit; performs a decompression operation; outputs each decompression data. The operation system is connected to the decompressing devices and stores the decompression data outputted from the decompressing devices in a storage device by using an asynchronous file input method. The present invention is provided to process the decompression data by using an asynchronous file input/output method, thereby not needing waiting time for arranging a decompression data sequence. The present invention is provided to minimize a bottleneck phenomenon in the storage device because the data is stored in the storage device by using an optimal scan method, thereby maximizing a speed performance effect obtained by the distribution parallel process and improving an image data storage speed for the storage device.
