GSAW97: Agenda and Presentations 

The spacecraft control community is focusing increasing attention on various forms of architectures. Studies on software architectures and related technologies have been commissioned by DOD programs such as Satellite Control Network (SCN), Milstar, Global Positioning System (GPS), Defense Meteorological Satellite Program (DMSP), Phillips Laboratory Space Research Program, Space Test and Evaluation (TE), and classified programs, as well as National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), commercial spacecraft programs, and commercial ground system product suppliers. A number of initiatives are underway to establish consensus reference architectures. However, up to now there has been very little technical interchange among these groups.

The Aerospace Corporation, in cooperation with the U.S. Air Force Space and Missile Systems Center (SMC) Ground Systems Integrated Product Team (GSIPT), is planning a series of annual workshops to bring together participants working in the Spacecraft Ground System (SGS) domain. The overall intent of these workshops is to expedite the transition to common consensus-based open software architectures for SGSs.

In the first of these workshops, GSAW97, participants will exchange information and air issues with the long-term goal of arriving at a community consensus on the following issues:

  • Criteria and tools for defining and evaluating SGS architectures
  • Role of software architecture in programs - impact on interoperability and standardization
  • Approaches for representing software architectures for SGSs
  • Implementation of SGS components/systems from architectures or frameworks
  • Software technologies for support of architecture (e.g., object-oriented technologies, middleware)
  • Mapping commercial products to reference software architectures
These workshops are partially supported by the University of Southern California - Center for Software Engineering and the Evolutionary Design of Complex Software (EDCS) Program which is being co-sponsored by the Defense Advanced Research Projects Agency (DARPA) and USAF Rome Laboratory. EDCS is a technology program which addresses the need for military systems to evolve over extended lifetimes, primarily through changes in their software. Technologies that are being developed as part of this program will be applied to software in the SGS domain via these workshops and related activities.

WORKSHOP DATES: February 26-28, 1997

Workshop will be held at The Aerospace Corporation facilities in El Segundo, California.
