I am not going to go into the specifics other then to say, It does not require two separate GPS systems, only that A DGPS system does require a separate receiver (an antenna) then the GPS receiver. But may be built into the GPS unit.
How it works on a specific A/C I do not care to discuss because their are to many different set ups to mention.
The "Differential" in the DGPS comes from the Radio signal that is received by the Differential receiver attached to or remote from the GPS unit itself. The computations are made according to the difference between what your GPS receiver is telling you and what the Differential receiver is telling you. Kinda like fixing a compass to your GPS but not having to use a map to verify your exact position etc.
Yes two or more GPS/ DGPS receiver units can be used in conjunction with each other, on A/C this is what they do to tell pitch, roll yaw and all those other things A/C do.
You do not require 2 GPS units to give you a more accurate fix or to use DGPS, only that you must have at least one GPS receiver(capable of DGPS) and one DGPS antenna attached to your GPS unit. That is all that I am saying.
Cheers
