Constructor Detail

TLEBatchLSModel

public TLEBatchLSModel(OrbitDeterminationPropagatorBuilder[] 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 Detail

configureDerivatives

protected TLEJacobiansMapper configureDerivatives(Propagator propagator)

Configure the propagator to compute derivatives.

Specified by:

configureDerivatives in class AbstractBatchLSModel

Parameters:

propagator - Propagator to configure

Returns:

mapper for this propagator

configureOrbits

protected Orbit configureOrbits(AbstractJacobiansMapper mapper,
                                Propagator propagator)

Configure the current estimated orbits.

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

Specified by:

configureOrbits in class AbstractBatchLSModel

Parameters:

mapper - Jacobian mapper

propagator - the orbit propagator

Returns:

the current estimated orbits
