Study and application on the CCSDS-based channel coding technique for the data transmission of compressed remote sensing image

With the development of spatial, temporal and spectral resolution of remote satellite imagery, the data acquired in the orbit must be compressed to meet the requirement of the real-time data downlink transmission. When the satellite data are transmitted in the downlink space channel, error code may be produced as a result of external interference. The error code will cause serious diffusion problem for the transmission of compressed data. According to the principle of the error control encoding and decoding, as well as the corresponding recommends of consultative committee for space data systems (CCSDS), a set of error control algorithm and scheme is proposed to satisfy the requirement of remote sensing satellite data transmission, combining the data compression practice. The emulation experiments show that the method is effective for preventing and reducing the error diffusion, so as to provide reliable data for the technique processing in the fields of remote sensing.
