Constructor Detail

CartesianCovariance

public CartesianCovariance(Supplier<FrameFacade> defaultFrameSupplier)

Create an empty data set.

Parameters:

defaultFrameSupplier - supplier for default reference frame if no frame is specified in the CCSDS message

Method Detail

validate

public void validate(double version)

Check is all mandatory entries have been initialized.

This method should throw an exception if some mandatory entries are missing or not compatible with version number.

Specified by:

validate in interface Section

Overrides:

validate in class CommentsContainer

Parameters:

version - format version

getEpoch

public AbsoluteDate getEpoch()

Get matrix epoch.

Returns:

matrix epoch

setEpoch

public void setEpoch(AbsoluteDate epoch)

Set matrix epoch.

Parameters:

epoch - matrix epoch

getReferenceFrame

public FrameFacade getReferenceFrame()

Get the reference frame.

Returns:

The reference frame specified by the COV_REF_FRAME keyword or inherited from metadata

setReferenceFrame

public void setReferenceFrame(FrameFacade referenceFrame)

Set the reference frame in which data are given.

Parameters:

referenceFrame - the reference frame to be set

getCovarianceMatrix

public RealMatrix getCovarianceMatrix()

Get the Position/Velocity covariance matrix.

Returns:

the Position/Velocity covariance matrix

setCovarianceMatrixEntry

public void setCovarianceMatrixEntry(int j,
                                     int k,
                                     double entry)

Set an entry in the Position/Velocity covariance matrix.

Both m(j, k) and m(k, j) are set.

Parameters:

j - row index (must be between 0 and 5 (inclusive)

k - column index (must be between 0 and 5 (inclusive)

entry - value of the matrix entry
