</span><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">As expressed during the presentation of the concept paper in the Hague, ESA is concerned that CCSDS approval of such OB for use in the EESS X-band may cause RFI beyond what computed in
SFCG and which resulted in an SFCG and an ITU-R recommendation on power flux density limits.</span><span style="font-size:8.5pt;font-family:"Arial","sans-serif""><br>
</span><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">The most logical solution would be to add the SFCG review cycle in the OB loop. ESA understands that this may cause the schedule to expand beyond the proponents' wishes.</span><span style="font-size:8.5pt;font-family:"Arial","sans-serif""><br>
</span><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">As compromise, ESA proposes to remove the indication of the bands by simply deleting the sentence</span><span style="font-size:8.5pt;font-family:"Arial","sans-serif""><br>
<br>
</span> "DVB-S2X can be used for both X and Ka-bands." <span style="font-size:8.5pt;font-family:"Arial","sans-serif""><br>
<br>
</span><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">ESA understands that removing this sentence from the concept paper does not prevent the bands from appearing somewhere else but is ready to run the risk and approach the issue again as needed.</span><span style="font-size:10.0pt;font-family:"Default Sans Serif""><br>
