Default Annular Doppler effect

I have found the link:
http://chaos.swarthmore.edu/courses/...er_Anomaly.pdf

""It is also possible to infer the position in the sky of a
spacecraft from the Doppler data. This is accomplished by

examining the diurnal variation imparted to the Doppler shift

by the Earth's rotation. As the ground station rotates underneath

a spacecraft, the Doppler shift is modulated by a sinusoid."


On the page 37 is wrote: "At early times the

annual term is largest. During Interval II, the interval of the

large spin-rate change anomaly, coherent oscillation is lost.

During Interval III the oscillation is smaller and begins to die

out."

Does it means that at the long distances no annual variation imparted to the
Doppler shift?
