I. Introduction
Precise determination of spacecraft performances and environments requires sampling of on-board sensors during actual missions [1]. Analysis of on-board sensor data, provided via telemetry, allows to reduce uncertainties in design parameters, resulting in residual improvements, with the goal of minimizing costs for future missions. Growing numbers of sensors and increasing sensor cadences require more on-board lossless data compression [2] and lossy data compaction [3] to provide the maximum amount of information over the bandwidth limited telemetry downlink. The incurring computational effort is excessive for the radiation hardened on-board computers (OBCs) in current use [4]. Driven by the growing demand for on-board computing power, efforts to introduce commercial off the shelf (COTS) products in space [5] result in additional computing power available [6] to close this gap.
