The results of applying Autonomy Requirements Engineering (ARE) to Nano-Satellite Systems

Abstract

The development of a self-adaptive system is complicated task as the model has many interlinked dynamic parts. Autonomy Requirements Engineering (ARE) tackles the dilemmas and issues these and other adaptive systems by extracting and the AR or the Autonomy Requirements. The system objectives which are crucial to the mission success are modeled by the GORE (Goal-Oriented Requirements Engineering) method. GORE comes under the ARE umbrella. This has great potential for a solution with regard to space systems which need many contingency plans particularly unmanned space systems. These need to be highly adaptive. The results of applying ARE to the CubeSat are presented here. Specifically MYSAT-1. In particular-to engineer the adaptation issues while it is out of Ground Station (GS) control and its feasibility. We have discovered and observed following the ARE approach enhances the process of eliciting the system requirements. It achieves this speculating and elaborating on the potential scenarios where autonomy is required in four cases, and hence defines the relationship between the system components. Furthermore, we deduced that a CubeSat system requires a combination between autonomous and human control. By enhancing the self-control capabilities, we can reduce human customization. The secondary value of this thesis has been to observe to that ability of that approach to handle to these systems and subsystems of these peculiar satellites. More importantly to evaluate that capability of the approach in performing that task. Hence the framework for this task requires a qualitative study though quantitative aspect would also be studied.
