[Ground-station] This looks a bit like Thuraya. Or not ?

[Howie DeFelice]

Thuraya, Inmarsat and Iridium are all narrowband low data rate solutions. It's unusual to see DVB-S2(x) used at symbol rates below 1 msps. Above 1 msps the DVB-S2(x) standard has become commonplace, mostly on the forward link of TDMA systems but also SCPC high rate modems. The big move now is to unify commercial satellite air interface with 5G. There is a 3GPP working group working on the standards. The idea is to make satellite a seamless part of the 5G network.

Thuraya, Inmarsat, and Iridium all use different signaling approaches, but they all appear to be very different from DVB-S2x which, I think, came out of the VSAT world.
I’m not saying that they couldn’t use it.  Do they plan to?  If so, for what reason?

For the ARAP, yes, this model is implementing the basic idea. Good spotting!

This is the sort of thing DVB-S2X was envisioned to deliver, especially with the Very low SNR modcods added to the standard.

Ok.
So, with all the cell phone technology involved, will it look something like this, but only on ham radio bands ?
Thuraya Satsleeve ?
Used on sat systems with footprint over Europe, Asia, Africa and Australia.
