Description
SKE is a software application for general-purpose Linux host servers that allows to emulate the partitioned environment designed for computers on-board satellites running mixed-criticality systems that require time and space partitioning and fault detection and isolation. The benefits of using SKE are manyfold, from helping to develop in Linux environments the mentioned systems that will run on top of the XtratuM/NG (XNG) hypervisor, up to be exploited by operational simulators to run on-board computers faster than real time. In this latter context, this paper shows how SKE is being integrated in the CNES’s KOSMOS framework to provide the on-board computer environment inside a full numerical simulator of a swarm of satellites. SKE is aimed to provide the expected functionality of the XNG hypervisor, offering faster-than-real-time performances when executing the flight software and still keeping a good level of representativity in terms of functional behaviour.
