      • ObservableSatellite

        public ObservableSatellite​(int propagatorIndex)
        Simple constructor.
        Parameters:
        propagatorIndex - index of the propagator related to this satellite
    • Method Detail

      • getPropagatorIndex

        public int getPropagatorIndex()
        Get the index of the propagator related to this satellite.
        Returns:
        index of the propagator related to this satellite
      • getClockOffsetDriver

        public ParameterDriver getClockOffsetDriver()
        Get the clock offset parameter driver.

        The offset value is defined as the value in seconds that must be subtracted from the satellite clock reading of time to compute the real physical date. The offset is therefore negative if the satellite clock is slow and positive if it is fast.

        Returns:
        clock offset parameter driver
      • getClockDriftDriver

        public ParameterDriver getClockDriftDriver()
        Get the clock drift parameter driver.

        The drift is negative if the satellite clock is slowing down and positive if it is speeding up.

        Returns:
        clock drift parameter driver
        Since:
        10.3
      • getClockAccelerationDriver

        public ParameterDriver getClockAccelerationDriver()
        Get the clock acceleration parameter driver.
        Returns:
        clock acceleration parameter driver
        Since:
        12.1
      • getQuadraticClockModel

        public QuadraticClockModel getQuadraticClockModel()
        Get a quadratic clock model valid at some date.
        Returns:
        quadratic clock model
