The method calculates the Doppler shift using the satellite location, the aircraft location, and data which defines flight characteristics.
If you are going to use the AES location and ADIRU data to cover its manouvering at any point in time, then the logical conclusion is that the AES will do the same for the SAT using a look-up table for the ephemeris data associated with the same time.

The SDU knows which satellite it is coupled with, and to my mind there is no reason for the above not to take place, i.e. the Sat is not about to do a "barrel roll" or look over the neighbors fence as it goes about its predefined orbital parameters.
