On the use of Ada tasking in the building of satellite control software
Tullio Vardanega · 2002
An increasing proportion of the critical control activities performed on board of modern satellite systems is nowadays being implemented in software. The resulting software systems have thus to accommodate a large spectrum of processing requirements, which shows an increasing demand for event-driven activities. Hence, process-oriented preemptive priority-based scheduling is most suited for use in such systems. This paper contends that the recent advances in the domain of hard real-time make Ada tasking particularly apt for it. This paper shows that, although a variety of reasons exist to date for not using any of the Ada tasking in critical applications, most of such reasons may be defeated by educated design and efficient implementations.>
