Abstract

As part of its small satellite R&D activities, Spar Aerospace Limited is studying the applicability of onboard real-time data compression to solve some problems of data storage onboard small satellites and of data delivery to remote users. To fulfill this goal, a collaboration was established with the University of Surrey Spacecraft Engineering Unit to test Spar's compression code on UoSAT-5 EIS images and have it ultimately executed onboard UoSAT-5. Image compression of the UoSAT-5 remote sensing data has been achieved by a number of algorithms including lossy methods such as the `discrete cosine transform' (DCT) related to the JPEG standard, the `block truncation' (BT), the `vector quantization (VQ) as well as lossless compression methods.
