Data Compression as a Means to Disseminate More METEOSAT Data over the Existing Channel

摘要

The paper describes the outcome of a study on data compression methods for operational remote sensing (meteorology), initiated by ESOC. The objective of the study was to determine the feasibility of data compression in the METEOSAT imagery-data dissemination mission. User requirements indicate that decompressed METEOSAT imagery should contain no errors. This implies that the data compression methods must be reversible and the compressed data must be protected against transmission errors using error-correcting coding methods. The compression ratio (about 2) that must be achievable is easily attainable with practical data compression methods which can be implemented in real-time operating hardware.
