Constructor Details

BatchLSModel

public BatchLSModel(PropagatorBuilder[] propagatorBuilders,
 List<ObservedMeasurement<?>> measurements,
 ParameterDriversList estimatedMeasurementsParameters,
 ModelObserver observer)

Simple constructor.

Parameters:

propagatorBuilders - builders to use for propagation

measurements - measurements

estimatedMeasurementsParameters - estimated measurements parameters

observer - observer to be notified at model calls

Method Details

configureHarvester

protected MatricesHarvester configureHarvester(Propagator propagator)

Configure the propagator to compute derivatives.

Specified by:

configureHarvester in class AbstractBatchLSModel

Parameters:

propagator - Propagator to configure

Returns:

harvester harvester to retrive the State Transition Matrix and Jacobian Matrix

configureOrbits

protected Orbit configureOrbits(MatricesHarvester harvester,
 Propagator propagator)

Configure the current estimated orbits.

For DSST orbit determination, short period derivatives are also calculated.

Specified by:

configureOrbits in class AbstractBatchLSModel

Parameters:

harvester - harvester for matrices

propagator - the orbit propagator

Returns:

the current estimated orbits
