Preface

1.1. Scope
This document provides the Software Requirements Specification for the Magdalena Ridge Observatory Interferometer (MROI) Automated Alignment System (AAS). Software Requirements Specification (SRS) documents capture the user need and contract between the software development team and the customer. The SRS describes functional requirements by use cases. Each use case (UC) describes the system's behavior under various conditions as the system responds to requests. SRS also describe non-functional requirements for the system's completion. SRS drives implementation of the software products. This document follows the guidelines for an SRS described in "MROI Software Project Management Plan" INT-409-xxx.xxx.[1].

1.2. Context
The Automated Alignment System (AAS) provides the real-time control, monitoring, and data acquisition for the MROI Automated Alignment System (AAS) sub-project. The AAS sub-project is described in "Requirements for the Automated Alignment System", INT-404-TSP-0003 [2].

1.3. Intended Audience
The primary audiences for this document are the stakeholders of the AAS and the MROI control software team. It is intended that software development will base designs on this SRS, and software testing will use this document as a reference to assess whether the software satisfies requirements.

1.4. Evolution of the SRS
The information in an SRS is intended to be evolving, but varying slowly, across the entire duration of the software project. The SRS achieves greater fidelity as the project progresses and requirements understanding matures. Each revision provides a baseline for software development activities and formally identifies the user needs for the software. The initial version of this SRS coincides with the development of the AAS Conceptual Design. Revisions to this document are anticipated in conjunction with the development of the Preliminary and Final Designs, and Software Change Orders. Revisions are also anticipated in conjunction with iterations of software development life-cycles.

1.5. Document Conventions
Each software requirement in this document is labeled for identification purposes with a unique tag in accordance with guidelines described in "MROI Software Project Management Plan" [1].
