Interface GLONASSOrbitalElements

All Superinterfaces:

TimeStamped

All Known Implementing Classes:

GLONASSAlmanac, GLONASSEphemeris

public interface GLONASSOrbitalElements
extends TimeStamped

This interface provides the minimal set of orbital elements needed by the GLONASSAnalyticalPropagator and the GLONASSNumericalPropagator.

Because input data are different between numerical and analytical GLONASS propagators the methods present in this interface are implemented by default. Depending if the user wants to use a GLONASSNumericalPropagator or a GLONASSAnalyticalPropagator he can create an instance of a GLONASSEphemeris or GLONASSAlmanac.

10.0
