Hi Dave, Nader,
A CubeSat Converter is certainly an interesting thought. In addition to the challenges (that's the hip cop-out from saying "problem" these days) that you noted, I'm thinking that the ConverterSat would also:
Have to be in the footprint of Es'hail So as a converter even only in the footprint for stations in the footprint but w/o the S and X equipment, it would only offer a 10-20 minute window to Es'hail the usual 3-6 times per day In trying to extend the footprint, it would need to be of a pretty high altitude itself in order to extend the footprint by much Being on the edge of the Es'hail footprint in order to extend it, requires more power/gain/pointing to connect with Es'hail
But I guess these are more "usefulness" challenges than the RF challenges of acting as the converter you have listed. It gave me thoughts about GOLF-TEE trying to bridge the gap, but would have design implications as you noted that at least wouldn't be possible in our current timeline.

Hi,
Interesting idea.
Problems to overcome:
Size of dish / patch required to be flown as part of satellite Attitude control and pointing in real time Power management Band width limitations Doppler correction Frequency stabilty
Any more folks?
