<span style="font-size:12.0pt">This looks like a very useful RFP and certainly something that will be used.

<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;line-height:normal">
<span style="font-size:12.0pt">The specification is well written and detailed. The concepts need to be defined as there are several undefined terms.

<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;line-height:normal">
<span style="font-size:12.0pt">There is an inconsistency in terminology in the first section. The first paragraph refers to the “spacecraft scheduling products” and the bullet points reference a “spacecraft contact schedule”. This should be normalized or at
least explained. <o:p></o:p></span></p>
