public class Phase extends AbstractMeasurement<Phase>
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.
WARNING: as of release 9.2, this feature is still considered experimental

public Phase(GroundStation station, AbsoluteDate date, double phase, double wavelength, double sigma, double baseWeight) throws OrekitException
This constructor uses 0 as the index of the propagator related to this measurement, thus being well suited for mono-satellite orbit determination.
