    public class OneWayGNSSPhase
    extends AbstractMeasurement<OneWayGNSSPhase>
    One-way GNSS phase measurement.

    This class can be used in precise orbit determination applications for modeling a phase measurement between a GNSS satellite (emitter) and a LEO satellite (receiver).

    The one-way GNSS phase measurement assumes knowledge of the orbit and the clock offset of the emitting GNSS satellite. For instance, it is possible to use a SP3 file or a GNSS navigation message to recover the satellite's orbit and clock.

    This class is very similar to InterSatellitesPhase measurement class. However, using the one-way GNSS phase measurement, the orbit and clock of the emitting GNSS satellite are NOT estimated simultaneously with LEO satellite coordinates.
