BFO model

Something I don't understand about the D3 compensation: what is the purpose to send a pilot frequency from Italia or the Netherlands, so that the 3F1 satellite measures/observes the doppler shift versus a point in Europe
1) when a shift versus Perth has to be corrected ?
2) when the actual compensation seems to be implemented, not onboard the sat, but on the ground in Perth ? (why send a pilot freq. to the sat ?).

The south trajectories outputed by the MC sim at 470 kts trying to fit (best fit in green) all the BTO/BFO values (red plots) excepted for 16:55 and 18:27): they remain compatible with the radar track, cross only the northern tip of Indonesia (80 km east of Banda Aceh).
