Exploit S/C realtime knowledge
role to play in each of these areas, both by reliably and predictably executing
the ground system's orders and by autonomously reacting to realtime events
to provide enhanced value above and beyond a “simple-minded” response to
ground requests. In the following subsections, each of the three objectives
will be discussed in a general fashion, with some specific examples cited to
illustrate general concepts and principles. Later, these topics will be touched
