Abstract : Software is of increasing importance in guidance and control systems and indeed in many cases is the pacing item in development. Guidance and control software, while embracing a wide range of software, has emphases which include high integrity considerations, hard real-time constraints, the implications of a still evolving hardware and systems architecture, and the need to meet delivery schedules with high productivity under the constraints of onerous customer requirements for documentation and visibility, and in the light of strong defence and air worthiness standards and requirements. Time schedules are frequently short since much guidance and control software is required early in the flight testing, and typically software development is undertaken in the context of still evolving requirements and developing programme phases. The software climate in which this takes place is one in which there is a general trend towards high level languages, integration of support tools, introduction of mathematical formalisms into the design and verification processes, control of software sizing and better cost estimating, and frequently a rapid turnover of programmers. There is often a wide gap between concept and practice, and organizations will succeed which can bridge the gap effectively, bringing modern methodologies, well supported by software tools, to bear on the problem and understanding how to apply these methodologies and use the tools. To assist this understanding the symposium covered general requirements on the software, software requirements capture, design methods and support environments for real- time software, coding techniques, and verification validation and certification.
