<p class="MsoNormal"><span style="font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">But in our view it makes only sense to put resources into such a project, if there are relevant launcher agencies who intend to use such a standard in the future. Might be it would be useful
to involve them in such a specification process (similarly as JSpOC in case of the CDM).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif""><o:p> </o:p></span></p>

an ICD (especially contact data among others).<o:p></o:p></span></p>

to hours) specified for a time span over several days or weeks and also including separation vector dispersions, and this for several objects.<o:p></o:p></span></p>
