    • Constructor Detail

      • ObservableSatellite

        public ObservableSatellite​(int propagatorIndex)
        Simple constructor.

        This constructor builds a default name based on the propagator index.

        Parameters:
        propagatorIndex - index of the propagator related to this satellite

      • ObservableSatellite

        public ObservableSatellite​(int propagatorIndex,
                           String name)
        Simple constructor.
        Parameters:
        propagatorIndex - index of the propagator related to this satellite
        name - satellite name (if null, a default name built from index will be used)
