Management of complex trades for space-ground systems - A case studyfor mission management
T. DOPPLICK · 7th Computers in Aerospace Conference · 1989
AMission management must change and improve as space-ground systems evolve from single function spacecraft (e.g. NASA's Hubbel Space Telescope) to multi-mission spacecraft (e.g. NASA's Space Station Freedom). It is the multi-mission spacecraft with its multi-instrument conflicts and on-orbit rescheduling that is really challenging mission management technology. Successfully evolving from predictive to more advanced mission management systems is very difficult and necessitates use of modern technologies including application of appropriate A1 technology. Future architectures must accommodate planningischeduling for conflict environments as well as on-orbit rescheduling. Emphasis must be placed on identifying architectures that provide clear paths for future growth. We have found that the concepts for multi-instrument conflicts and frequent on-orbit rescheduling are readily generalized for application to the entire range of mission management problems. This is a true for attempts to generalize predictive systems to handle conflict and/or rescheduling. Adding and/or overlaying design changes to architectures not designed to handle initial or increased rescheduling can quickly lead to disaster.
