Found this saying Voyager has a pointing accuracy of 0.1 degrees: https://www.quora.com/How-precise-are-spacecrafts-like-New-Horizons-Voyager-I-and-Voyager-II-able-to-point-their-antenna-towards-Earth https://www.quora.com/How-precise-are-spacecrafts-like-New-H... From the distance of Voyager, I doubt it makes any difference where Earth is for pointing the antenna. As in, it is pointing to the same spot no matter the day or season. They probably dial in an inertial coordinate and that is it.
