public class AngularAzEl extends AbstractMeasurement<AngularAzEl>
Class modeling an Azimuth-Elevation measurement from a ground station. The motion of the spacecraft during the signal flight time is taken into account. The date of the measurement corresponds to the reception on ground of the reflected signal.- Since:
