J2PropagatorGetEvaluator Method

Gets an evaluator that can propagate at individual dates.

This evaluator propagates the orbit state. The result of evaluating will be a MotionT corresponding to the orbital state at the given JulianDate expressed in the propagator's ReferenceFrame.

Note: when evaluating with this evaluator, it may be more efficient to specify times using an arithmetically safe TimeStandard to avoid the need to convert in order to perform the propagation. The length of a time step may be different in different TimeStandards. So be careful when specifying times.

Gets an evaluator that can propagate at individual dates.

This evaluator propagates the orbit state from InitialConditions at OrbitEpoch based on the GravitationalParameter, J2ZonalHarmonicCoefficient and ReferenceDistance. The result of evaluating will be a Motion<Cartesian> corresponding to the orbital position and velocity at the given JulianDate expressed in the propagator's ReferenceFrame.
