Abstract
This paper reports on an investigation into the application of data compression techniques as a means of reducing the ‘on-ground’ data storage requirements that are associated with many space research programmes. The paper presents and compares quantitatively various compression techniques based on the Shannon-Fano, ‘run-length’ and Hadamard transformation methods of source encoding. The compression ratios obtained when applying the techniques to actual satellite data are given and some new basic theory relating to ‘run-length’ encoding is presented.Keywords
