<p class="p1"><span style="font-size:12.0pt;font-family:Courier">Regarding THRUST_ACCELERATION: There are two instances of this keyword in the document (one in Table 3-3 and one in Annex A), and five total instances of the word "acceleration" (four associated
with this keyword). The fifth instance of "acceleration" is irrelevant to this keyword. The Description in Table 3-3 states "The object’s acceleration due to
<span style="color:red">in-track thrust </span>used to propagate the state vector and covariance to NOMINAL_RENTRY_EPOCH (if a controlled re-entry)", which seems to clearly indicate the in-track nature of the acceleration. The Description in Annex A (the ICS
Proforma) states "Object’s acceleration used in OD and propagation", i.e., it does not include the "in-track" qualification. Although Section 3 and Annex A are both normative, I think that implementers are more likely to use Table 3-3 than Annex A in creating
an RDM processor. However, it would be easy to add the word "in-track" in Annex A; page numbering would NOT be affected.<o:p></o:p></span></p>

<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">My understanding is that at this point (after agency review and prototyping) we are dealing with editorial comments only. There were multiple opportunities to get technical comments during the White
Book iterations. I think removing/re-scoping keywords is well beyond our current purpose, could result in the need to redo at least some of the prototyping, and set back the entire process by at least one year. If you still have technical points you do not
think are addressed in Red Book 1.7, I suggest we deal with those in RDM v2.</span>
