DSSTBatchLSModel

public DSSTBatchLSModel(OrbitDeterminationPropagatorBuilder[] propagatorBuilders,
                        List<ObservedMeasurement<?>> measurements,
                        ParameterDriversList estimatedMeasurementsParameters,
                        ModelObserver observer,
                        PropagationType propagationType,
                        PropagationType stateType)

Simple constructor.

Parameters:

propagatorBuilders - builders to use for propagation

measurements - measurements

estimatedMeasurementsParameters - estimated measurements parameters

observer - observer to be notified at model calls

propagationType - type of the orbit used for the propagation (mean or osculating)

stateType - type of the elements used to define the orbital state (mean or osculating)

Method Detail

configureDerivatives

protected DSSTJacobiansMapper 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
