Constructor Detail

SemiAnalyticalKalmanEstimatorBuilder

public SemiAnalyticalKalmanEstimatorBuilder()

Default constructor. Set an Extended Semi-analytical Kalman Filter.

Method Detail

build

public SemiAnalyticalKalmanEstimator build()

Construct a KalmanEstimator 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.

Returns:

a new KalmanEstimator.

decomposer

public SemiAnalyticalKalmanEstimatorBuilder decomposer(MatrixDecomposer matrixDecomposer)

Configure the matrix decomposer.

Parameters:

matrixDecomposer - decomposer to use for the correction phase

Returns:

this object.

addPropagationConfiguration

public SemiAnalyticalKalmanEstimatorBuilder addPropagationConfiguration(DSSTPropagatorBuilder builder,
                                                                        CovarianceMatrixProvider provider)

Add a propagation configuration.

This method must be called once initialize the propagator builder used by the 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 SemiAnalyticalKalmanEstimatorBuilder 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.
