public class AngularRaDec extends AbstractMeasurement<AngularRaDec>
Class modeling an Right Ascension - Declination measurement from a ground point (station, telescope). The angles are given in an inertial reference frame. 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:
