Package org.orekit.propagation.sampling

This package provides interfaces and classes dealing with step handling during propagation.

It is used when a Propagator is run in master mode. In this mode, the (master) propagator integration loop calls (slave) application callback methods at each finalized step. The callback methods must implement the OrekitFixedStepHandler interface for fixed step sampling or the OrekitStepHandler interface for variable step sampling.

Both regular propagators using double numbers for state components and field based propagators using any kind of field are available. A typical example is to use derivative structure objects to propagate orbits using Taylor Algebra, for either high order uncertainties propagation or very fast Monte-Carlo simulations.

The PropagatorsParallelizer class can be used to propagate orbits for several spacecrafts simultaneously, which can be useful for formation flying or orbit determination for complete navigation constellations.

The low level interfaces and classes (OrekitXxx) are heavily based on classes with similar names in the ode package from the Hipparchus library. The changes are mainly adaptations of the signatures to space dynamics:
