SOHO GROUND SEGMENT, SCIENCE OPERATIONS, AND DATA PRODUCTS

We describe the ground segment, pre-launch operations concepts, and da ta products supporting the SOHO mission. Our goal is threefold: first, we provide a historical view of the design and development of the sys tems described here, as a background perspective to those who will use the system and those who may build such systems for future missions. Second, because we hope that many researchers from the solar and space physics communities will visit these facilities during the mission, w e provide an overview for the benefit of the end-user. We anticipate t hat visitors to GSFC may plan observations for one or more of SOHO's c omplement of instruments, and such researchers may use the facilities to analyze data gathered by the SOHO instruments. Third, we present th e working plan for investigators with groundbased or other spacebased instruments to collaborate with SOHO.
