<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'>Q: Who
should use Hummingbird?<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'>A: The
target is a system for nano / micro satellites.<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'>The system
is not intended to, and never will be, replace major agency systems, used to
control science, earth observation and deep space probes. For these systems
much more mature and systems are needed, and a number of such systems already
exist.<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'>What is
missing is a low cost, easy to install, simple to use system, which university
groups and private industry can use to provide simple solutions to nano / micro
satellite missions.<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'>Q: Why not a
generic monitoring and control system?<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'>A: Because
it would break the concept of simplicity.<o:p></o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></b></p>
<p class=MsoNormal><b><span style='font-size:12.0pt;color:#1F497D'>The core
concept of Hummingbird, that of a system ordered according to a Space System
Model could of cause easily be used to model other, non-space related systems.
However we would then have to use generic terms as well, and thing about
generic problems, instead of solving the problem at hand. That’s the
first step to failure.<o:p></o:p></span></b></p>

is yet to be decided, but it will be open and not GPL. LGPL is the most likely
candidate, as we would like you to use the software and link with it without
