public class Phase extends GroundReceiverMeasurement<Phase>
Class modeling a phase measurement from a ground station.The measurement is considered to be a signal emitted from a spacecraft and received on a ground station. Its value is the number of cycles between emission and reception. The motion of both the station and the spacecraft during the signal flight time are taken into account. The date of the measurement corresponds to the reception on ground of the emitted signal.
