Default constructor. Set an Unscented Semi-analytical Kalman filter.

Method Detail

build

public SemiAnalyticalUnscentedKalmanEstimator build()

Construct a SemiAnalyticalUnscentedKalmanEstimator from the data in this builder.

Before this method is called, addPropagationConfiguration() must have been called at least once, otherwise configuration is incomplete and an exception will be raised.

In addition, the unscentedTransformProvider() must be called to configure the unscented transform provider use during the estimation process, otherwise configuration is incomplete and an exception will be raised.

Returns:

a new SemiAnalyticalUnscentedKalmanEstimator.

decomposer

public SemiAnalyticalUnscentedKalmanEstimatorBuilder decomposer(MatrixDecomposer matrixDecomposer)

Configure the matrix decomposer.

Parameters:

matrixDecomposer - decomposer to use for the correction phase

Returns:

this object.

unscentedTransformProvider

public SemiAnalyticalUnscentedKalmanEstimatorBuilder unscentedTransformProvider(UnscentedTransformProvider transformProvider)

Configure the unscented transform provider.

Parameters:

transformProvider - unscented transform to use for the prediction phase

Returns:

this object.

addPropagationConfiguration

public SemiAnalyticalUnscentedKalmanEstimatorBuilder addPropagationConfiguration(DSSTPropagatorBuilder builder,
                                                                                 CovarianceMatrixProvider provider)

Add a propagation configuration.

This method must be called once initialize the propagator builder used by the Semi-Analytical Unscented Kalman Filter.

Parameters:

builder - The propagator builder to use in the Kalman filter.

provider - The process noise matrices provider to use, consistent with the builder.

Returns:

this object.

estimatedMeasurementsParameters

public SemiAnalyticalUnscentedKalmanEstimatorBuilder estimatedMeasurementsParameters(ParameterDriversList estimatedMeasurementsParams,
                                                                                     CovarianceMatrixProvider provider)

Configure the estimated measurement parameters.

If this method is not called, no measurement parameters will be estimated.

Parameters:

estimatedMeasurementsParams - The estimated measurements' parameters list.

provider - covariance matrix provider for the estimated measurement parameters

Returns:

this object.
