GSAW is an annual workshop that facilitates exploration of issues and potential for consensus in software architectures for spacecraft ground systems (SGSs). It provides an international forum for SGS users, developers, and researchers to share their experiences through presentations, working groups, and panel discussions.

Emphasis is on the dissemination of new ideas and lessons learned in the creation, application, and evaluation of software architectures that meet the technological challenges of SGS development

At GSAW 1999 a presentation
(pdf) titled "Software Architectures: What are we Building?"  was made by Roger J. Dziegiel, Jr (AFRL/IFTD) on Architecture-Based Development And Evolution (ARCHIE).  The project includes multiple projects including Stanford's (David Luckham) Rapide work.

The project was based on a recognition of the following problems:

  • Paradigm shift to the development of application families and an increased reliance on component reuse necessitates advanced mechanisms for representing system architecture
  • No commonly accepted definition of architecture beyond notions of components and connectors; emerging ADLs, but terminology is not fixed and competing languages and logics are used:
    • Difficulty predicting/analyzing functional/extrafunctional characteristics of integrated components
    • Architectural archeology (e.g., recovery of architectural information from legacy systems)
