Using calculations based on the Keplerian elements for a specified satellite is an effective method for predicting the satellite's location at a given time. The Keplerian elements provide a defined set of orbital parameters that describe the satellite's orbit, including factors such as the semi-major axis, eccentricity, inclination, and true anomaly. These parameters allow one to describe the satellite's position in its orbit at any point in time.

The Keplerian elements detail the shape and orientation of the orbit, making them essential for determining the satellite's position relative to Earth or another reference point. By applying Kepler’s laws of motion and time calculations, one can accurately determine where the satellite will be at any given moment.

The other choices presented are not viable methods for predicting a satellite’s position as effectively as utilizing the Keplerian elements. For instance, Doppler data can provide frequency shifts but does not directly convey positional information. Meanwhile, manipulating mean anomaly and orbital inclination directly does not provide the comprehensive context needed for accurate location predictions.
