COMMERCIAL-OFF-THE-SHELF TELEMETRY FRONT-END PROTOTYPINGHogie, Keith, Weekley, Jim, Jacobsohn, Jeremy 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The world of data communication and networking has grown rapidly over the last decade,
and this growth has been accompanied by the development of standards that reflect and
facilitate the need for commercial products that work together in a reliable, robust, and
coherent fashion. To a great extent this commercialization, with its increasing performance
and diminishing cost, has not been adapted to the data communication needs of satellites.
As budgets and mission development and deployment timelines shrink, space exploration
and science will require the development of standards and the use of increasing amounts of
off-the-shelf hardware and software for integrated satellite ground systems.
The Renaissance project at NASA/Goddard Space Flight Center has engaged in rapid
prototyping of ground systems using off-the-shelf hardware and software products to
identify ways of implementing satellite ground systems "faster, better, cheaper". This paper
presents various aspects of these activities, including issues related to the configuration
and integration of current off-the-shelf products using telemetry databases for existing
spacecraft, an analysis of issues related to the development of standard products for
satellite communication, tradeoffs between hardware and software approaches to
performing telemetry front-end processing functions, and proposals for future standards
and development.
