Data Compression Tools

TEC-EDP has compiled a set of tools supporting test / evaluation and implementation of data compression algorithms. For more information and support, please contact:

WhiteDwarf data compression evaluation tool

WhiteDwarf Screenshot
WhiteDwarf is an application that supports the evaluation of compression algorithms by the prospective users of those algorithms. It allows users to compress and decompress their own data files, and optimize algorithm choice and compression parameters by testing with representative user-selected datasets. It also allows users to perform pre-processing functions on their files. Using this tool, users can test how different combinations of algorithm and compression parameter perform when compressing samples of their own data. These combinations may be stored, exported and imported. The generation of test reports is also supported.

The tool is made available to ESA supported projects and to companies in ESA member states. To obtain an authorized copy, please refer to the WhiteDwarf project page on the European Space Software Repository (ESSR):

PRDC Reference SW

A Reference SW implementing the RICE algorithm (CCSDS 121 standard)is available upon request. The SW is available as an executable for Windows and Linux.

CCSDS 123.0-B-1 Multispectral & Hyperspectral Lossless Data compression

The SW implementing the new CCSDS 123 standard is available under European Space Agency Public License. The SW is available for Windows and Linux. Download here.
