[SSG] [CESG] ?Band Bins? for SCID assignments

[Shames, Peter M (312B)]

Hi Keith,

I agree that we need some tie to specific frequencies.  In the frequency band table that I adopted from the IEEE the bands are separated along exact fraequencies, such as  8 Ghz – 12 GHZ.   This table was in the spredsheet I sent out, but I did not repeat it in the email itself.   It appears that there are separate, and somewhat different, identifiers in use in the EU, NATO, ECM, ITU, and EIA / IEC waveguide communities.  I propose that we adopt one, the IEEE, and stick to it.  This is not to suggest that there aren’t other, far more precise and carefully identified frequency bands that the SFCG and ITU care about, but those more crisp distinctions do not really help us in this situation.

That said, this still leaves us with potentially a large number of “bands”, much more than is useful for our purposes.  And that is why I proposed that we create these “Band Bins”.  I’ve augmented those proposed Band Bins, below, with the frequencies that they include.

Purely based on pragmatic considerations I would suggest that we could create “Band Bins” that looked like this:
·Everything below S-Band (HF, VHF, UHF, L)   0-2 GHz
·S-Band & C-Band   2-8 GHz
·X-Band   8-12 GHz
·K-Band (Ku, K, Ka) 12-40 GHz
·None or unstated

This is, of course, just a proposal, but it is based on A) the IEEE frequency Bands and their associated frequency ranges, and B) a pragmatic binning of these that provides separate “bins” for S/C operating at sufficiently different frequencies.

Regards, Peter

I would suggest that there be SOME mapping of the band bin edges to specific (numerical) frequencies, whether it’s direct or whether CCSDS defines or references a specific standard of set of standards for where that bins are.

Alternately, and FAR more complicated, a SCID could be associated with some filter (energy outside that filter < XXXdbM).  That’s probably much more trouble than it’s worth, and the bins seem better to me.

Peter,
        with respect to your proposal below, if imit will be implemented I do recommend keeping consistency with the headers of the IOAG RF assets table (to be modified I think) where the frequency bands are explicity addressed with numbers.

Purely based on pragmatic considerations I would suggest that we could create “Band Bins” that looked like this:
·Everything below S-Band (HF, VHF, UHF, L)
·S-Band & C-Band
·X-Band
·K-Band (Ku, K, Ka)
·None or unstated

Regards

Gian Paolo
