AggregateBoundedPropagator
public AggregateBoundedPropagator(Collection<? extends BoundedPropagator> propagators)
Create a propagator by concatenating severalBoundedPropagator
s.- Parameters:
propagators
- that provide the backing data for this instance. There must be at least one propagator in the collection. If there are gaps between theBoundedPropagator.getMaxDate()
of one propagator and theBoundedPropagator.getMinDate()
of the next propagator an exception may be thrown by any method of this class at any time. If there are overlaps between theBoundedPropagator.getMaxDate()
of one propagator and theBoundedPropagator.getMinDate()
of the next propagator then the propagator with the latestBoundedPropagator.getMinDate()
is used.

AggregateBoundedPropagator
public AggregateBoundedPropagator(NavigableMap<AbsoluteDate,? extends BoundedPropagator> propagators, AbsoluteDate min, AbsoluteDate max)
Create a propagator from several constituent propagators.- Parameters:
propagators
- that provide the backing data for this instance. Each propagator is used from the date of it's key in the map until the date of the next key. The first propagator is also used before the first key and the last propagator after the last key.min
- the value forgetMinDate()
.max
- the value forgetMaxDate()

Method Detail
-
getPropagatorsMap
public TimeSpanMap<BoundedPropagator> getPropagatorsMap()
Get the propagators map.- Returns:
- propagators map
- Since:
- 12.1
-
getPropagators
@Deprecated public NavigableMap<AbsoluteDate,BoundedPropagator> getPropagators()
Deprecated.as of 12.1, replaced bygetPropagatorsMap()
Get an unmodifiable view of the propagators map.The key of the map entries are the
min dates
of each propagator.- Returns:
- unmodifiable view of the propagators map
- Since:
- 12.0

basicPropagate
protected SpacecraftState basicPropagate(AbsoluteDate date)
Description copied from class:AbstractAnalyticalPropagator
Propagate an orbit without any fancy features.This method is similar in spirit to the
AbstractAnalyticalPropagator.propagate(org.orekit.time.AbsoluteDate, org.orekit.time.AbsoluteDate)
method, except that it does not call any handler during propagation, nor any discrete events, not additional states. It always stop exactly at the specified date.- Overrides:
basicPropagate
in classAbstractAnalyticalPropagator
- Parameters:
date
- target date for propagation- Returns:
- state at specified date
-
getPVCoordinates
public TimeStampedPVCoordinates getPVCoordinates(AbsoluteDate date, Frame frame)

of the body in the selected frame.- Specified by:
getPVCoordinates
in interfacePropagator
- Specified by:
getPVCoordinates
in interfacePVCoordinatesProvider
- Parameters:
date
- current dateframe
- the frame where to define the position- Returns:
- time-stamped position/velocity of the body (m and m/s)
-
getPosition
public Vector3D getPosition(AbsoluteDate date, Frame frame)
Description copied from interface:Propagator
Get the position of the body in the selected frame.- Specified by:
getPosition
in interfacePropagator
- Specified by:
getPosition
in interfacePVCoordinatesProvider
- Parameters:
date
- current dateframe
- the frame where to define the position- Returns:
- position of the body (m and)
-
propagateOrbit
protected Orbit propagateOrbit(AbsoluteDate date)
Description copied from class:AbstractAnalyticalPropagator

- extrapolated parameters
-
getMinDate
public AbsoluteDate getMinDate()
Description copied from interface:BoundedPropagator
Get the first date of the range.- Specified by:
getMinDate
in interfaceBoundedPropagator
- Returns:
- the first date of the range
-
getMaxDate
public AbsoluteDate getMaxDate()
Description copied from interface:BoundedPropagator
Get the last date of the range.- Specified by:
getMaxDate
in interfaceBoundedPropagator
