<div style="color: rgb(0, 0, 0); font-family: Calibri, sans-serif; font-size: 14px;">
<span style="font-size: 16px;">Please find attached the SEA resolution concerning the r</span>equest for CCSDS Agency HoD and spectrum managers to provide actual spectrum allocations for active spacecraft. This was discussed and agreed during the recent CESG
meeting. The motivation is to ensure that we have accurate information to use to assign spacecraft to frequency bins.</div>

<span style="font-size: 16px;">The CESG has discussed the proposal to increase available Spacecraft ID (SCID) namespace</span><span style="font-size: 16px;">, and that</span></div>
<div style="color: rgb(0, 0, 0); font-family: Calibri, sans-serif; font-size: 14px;">
<span style="font-size: 16px;">The number of available SCIDs, particularly for Type 2 (AOS) has reached a critical point where only two are unallocated, and that</span></div>

<font face="Calibri,sans-serif"><span style="font-size: 16px;">The CESG believes that the creation of a set of frequency bins for allocation of SCIDs will alleviate this problem by significantly increasing the usable namespace, and that</span></font></div>
<div><span style="font-size: 16px; font-family: Calibri, sans-serif;">The SANA Operator has determined that only 30% of the currently identified frequency assignments in the SCID registry are accurate, and that</span></div>
