International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper reports on the Space Shuttle, Record and Playback Subsystem (RPS) upgrade
project turnaround brought about through extensive collaborative software development.
The new project and systems engineering methodologies employed on this project resulted
in many positive effects over the status quo method employed to develop and upgrade
systems. These effects include; 1) a reduction in the initial software development costs, 2)
a reduction in the development timeline, 3) improved marketability of the software
technology developed, 4) improved product quality deployed to operations, and 5)
improved maintainability. Attributes within each of the aforementioned are examined in
support of these assertions.
Prior to implementing this new method, the RPS upgrade project had been under
development for seven years using the standard software development method. This
involves developing custom applications using Commercial Off The Shelf (COTS)
hardware, operating systems and compilers. A change in strategy was effected on this
pathfinder project by adopting a COTS telemetry ground station software package to
provide basic ground station functionality and building additional required capabilities to
complete the project. The merits of having employed this methodology are explored using
the probable outcome of continued custom software development as a basis for
comparison .
This collaboration between the United Space Alliance (USA) and AP Data Systems
Inc.(an AP Labs company), resulted in software innovations in FM and PCM processing
software as well as general ground station management software. The four technology
transfer submittals for new software innovations resulting from this collaboration are
discussed.
