[Sls-rfm] Fw: GSFC's Response to RFM Action Items

[Enrico.Vassallo at esa.int]

Dear All,

please find below the response by NASA/GSFC on AI-20_02, -03 and -04.

I guess that response to AI_20-03 may trigger further actions on the 
proponents of the relevant recommendation.

Best Regards, Enrico

Enrico,
 
Below is GSFC’s response to the RFM WG action items:
 
AI-20_02         Indicate if the recommendation should be for generic 
earth-to-space links or only for earth-to-moon links
NASA/GSFC doesn't know of any planned missions with the 22 GHz uplink that 
are not lunar missions, but would be ok with this being generic for all 
near-Earth missions.
 
AI-20_03         Indicate if the included modulation schemes and data 
rates are sound
On the proposed modulations, GSFC has the following questions:
What is the driver for the higher order mods on the uplink? 
Are there any mission profiles? 
Anyone cares about spectrum on uplink?
What is the requirement on the failure rates for the higher order mods?
Do the higher order mods for uplink need to be further analyzed?
 
AI-20_04        Provide additional considering and recommends as needed
None, since we don't have any other mission profiles to consider.
 
Thank you,
GSFC RFM WG Members (Shannon, Wai, Victor, Wing)
