People that record music professionally don't buy an android phone and settle for that because of the severe restrictions on the hardware optimisation it imposes.
Likewise, people that are concerned about optimising the radio link are not likely to accept restrictions in the receiver design for instance.
What kind of restrictions? Isn't a VITA data stream broadband SDR data? The entire radio implementation would seemingly be under the control of the client.
I would assume that one of the value propositions of having many ground stations to choose from is that one could simply rent one that was closest to the next flyover.
So I'm curious what factors you are thinking of that would not make sense as part of the service offering but would be needed by would-be customers of the service?
