I'm not actually sure which information / technology was provided from the Ascians to Allag directly; perhaps the knowledge of the Paragons was utilized in the design of both the weapons and the satellite. Maybe it was the knowledge about how a primal might be manipulated into eternal limbo. The game has been pretty unspecific about that; I suppose because there's no reliable vector for that information.

Who was there to see?
The Ascians gave Allag the Heart of Sabik to use as the core for Ultima Weapon and this had the rather unique ability to imprison primals and use their powers at will. I wouldn't be surprised if Omega was similarly built around some kind of Ascian core. As far as we're aware it was Omega that defeated and imprisoned Bahamut, right?

The only other technologies that Allag might have been given would be the neurolinks or the artificial prayer channeling devices, though it wouldn't be too much to think Allag developed these themselves.
