The time step for propagation of the spacecraft using the ephemeris. A StepSize of 0.0 means the Spacecraft will advance to the next entry in the ephemeris. Otherwise, the Spacecraft using the ephemeris will advance forwards or backwards by StepSize seconds. This property has no effect when producing an ephemeris file.
