<div>Bonjour SANA,</div>
<div> </div>
<div>I have a request in preparation for SCIds of 25 satellites in a small constellation.</div>
<div>They say they need 25 different codes in Version 1 for TM/TC and 25 different codes in Version 2 for the Payload link.</div>
<div> </div>
<div>First time for CNES, but I guess other CCSDS Members may already have brought such case to the SANA…</div>
<div> </div>
<div>I know the limitations on assignment of new SCId codes, but I am not sure of the situation in each frequency band.</div>
<div>I’ll clarify with them the exact frequency bands, but I already know they have S-Band for Earth Observation. Is that band overcrowded already?</div>
<div> </div>
<div>My other question is about the constellations: is there any particular recommendation from the SANA on how to address requests for multiple satellites ?</div>
<div>I remember this was discussed some years ago but I couldn’t find the conclusions, nor I can remember if the discrimination with frequency bands was established after that discussion and if those conclusions were updated.</div>
<div> </div>
<div>Thank you for your clarifications on these question.</div>
<div> </div>
<div>Of course, I brought the ULSP to their attention but I’m not sure this company is ready to migrate as they plan to launch within the next two years. We will see…</div>
<div> </div>
<div>Best regards</div>
<div> </div>
