[SOIS-WIR] Last version of SFCG REC on lunar frequency bands (SFCG REC 32-2R5)

[Issler Jean-Luc]

Dear Kevin, dear all,

Please find here (if you have not it already) the last version of the SFCG recommendation on the communication and PNT frequency bands in the lunar region, issued on the SFCG web site a few weeks ago

Also FYI, I am in charge of coordinating an action item for next SFCG meeting (june 2024) to study the possibility to (hopefully) extend the SFCG lunar surface wireless band from 2503.5-2655 MHz to 2503.5-2690 MHz. Any feed-back from CCSDS SOIS/WIR member(s) indicating an usefulness of such a band extention would significantly increase the chances of SFCG recommending it.

Thank you so much for any feed back

Have a good day and a nice summer continuation

Very best regards

Jean-Luc

PS: Please find below CNES's rationale for its proposal to extend the 2503.5-2655 MHz lunar surface wireless band to 2503.5-2690 MHz band (as you know, CNES opposes to the idea of adding 2500.0-2503.5 MHz to this lunar wireless bands for the reasons explained just below, but the 35 MHz that we are proposing to add are certainly more interesting for wireless than adding 3.5 MHz only). Moreover, to be noted: the 2655-2690 MHz band is a secondary radioastronomy band, but the RadioAstronomers present to last SFCG meeting agreed about the wireless band extension proposed by CNES, because of this secondary ITU status (and not primary radio astronomy), while it is a primary wireless band !
