Dear Kevin, dear all,
Please find here attached 2 SFCG recommendations resulting from the SFCG meeting last june, in case you would not have it already:
- REC 32-2R6 (Freqs for lunar Region) which has been updated (this rec is already taken into account by the CCSDS 883 standard).
- REC 43-1, which is a new recommendation dedicated to the protection of lunar in-situ PNT from lunar surface wireless links.
I suggest that references to SFCG REC 43-1 to be added in the CCSDS 883 standard and in any other future CCSDS standard which would concern lunar wireless surface links.
The provisional SFCG REC 43-1 is already refered in LunaNet Interoperability Specifications V5, and REC 43-1 will likely be refered in LNIS V6. The recommended maximum -121 dBW/m2/MHz PFD limit from lunar wireless links in the 2483.5-2500 MHz band at the input of the PNT receive antenna is unchanged from "prov-43-1" to "43-1".
Hoping these informations and my suggestion to be usefull.
Have a nice day and a good summer continuation.
Very Best Regards
Jean-Luc
