public static interface EphemerisFile.SatelliteEphemeris
EphemerisFile
.
A satellite ephemeris consists of one or more EphemerisFile.EphemerisSegment
s.
Segments are typically used to split up an ephemeris at discontinuous events, such
as a maneuver.

Ephemeris segments are typically used to split an ephemeris around discontinuous events, such as maneuvers.
AbsoluteDate getStart()
The date returned by this method is equivalent to
getPropagator().getMinDate()
.
AbsoluteDate getStop()
The date returned by this method is equivalent to
getPropagator().getMaxDate()
.

In order to view the ephemeris for this satellite as a Propagator
several conditions must be met. An Orekit Frame
and TimeScale
must be constructable from the frame and time scale specification in the
ephemeris file. This condition is met when EphemerisFile.EphemerisSegment.getFrame()
and EphemerisFile.EphemerisSegment.getTimeScale()
return normally for all segments
. If there are multiple segments they must be adjacent
such that there are no duplicates or gaps in the ephemeris. The definition of
adjacent depends on the ephemeris format as some formats define usable start
and stop times that are different from the ephemeris data start and stop times.
If these conditions are not met an OrekitException
may be thrown by
this method or by one of the methods of the returned Propagator
.
Each call to this method creates a new propagator.
