The case study looks at the issue of space situational awareness (SSA). In this paper we use a case study from aerospace engineering to showcase the applicability of a cloud-based architecture. The variety of available cloud-based architectures combined with a utility pricing model makes using a cloud-based architecture applicable to many scientific and engineering problems.

a managed OS, and Software as a Service (SaaS) e.g. virtual machines, Platform as a Service (PaaS) e.g. The key cloud-based solutions can be divided into three categories: Infrastructure as a Service (IaaS) e.g. Many cloud products offer a finished software solution rather than just infrastructure for example, Microsoft, Google and Apple offer cloud based services, such as Hotmail, Gmail and iCloud respectively, directly to end users. Most cloud providers, such as Apple, Amazon, Google and Microsoft offer a pay-as-you-go pricing model for software and infrastructure, which is often referred to as a utility pricing model. We demonstrate the feasibility of solving the space situational awareness problem with a cloud-based architecture and note that as time goes on and debris levels rise due to future collisions, the inherent scalability offered by a cloud-based solution will be invaluable.Ī variety of software and infrastructure solutions are referred to as cloud products, and although there is not a formal definition for cloud computing, the solutions tend to have much in common. We examine the strengths that cloud-based solutions offer in general and how these specifically fit to the challenges of space situational awareness, before describing the architecture we designed for this problem.
We also discuss active debris removal, which would be necessary to stabilise the debris population at current levels. This concerns tracking the hundreds of thousands of known objects in near-Earth orbits, and determining where it is necessary for satellite operators to conduct collision-avoidance manoeuvres to protect their satellites. We begin by introducing the background to the work and to the area of space situational awareness. In this paper we report upon the cloud-based solution that we designed and implemented for space situational awareness.
