摘要：
This paper analyses the performance of an Attitude and Orbital Control System for the Olympus Satellite. The system was designed using HRT-HOOD and implemented in Ada 83 augmented with some of the facilities of Ada 9X. The program consisted of multiple tasks communicating via protected shared data areas, A worst-case execution time analysis tool was used to estimate the execution time of each task, and Deadline Monotonic schedulability analysis was used to predict the system performance, taking into account all kernel overheads. An instrumented version was also produced to gather statistics on the actual run-time performance.
