Constructor Detail

BasicMultiOrbitalCovarianceProvider

public BasicMultiOrbitalCovarianceProvider(Covariance initialCovariance,
                                           Map<SpacecraftStateProvider,JacobiansMapper> scProviderMap)

Constructor

Parameters:

initialCovariance - The initial covariance to propagate

scProviderMap - The map of spacecraft state providers and their mapper. The spacecraft state providers are used to propagate the initial covariance. The mappers are used to extract partial derivatives from the spacecraft states
Conditions:

• Entries of this map must be ordered in the same order of the provided covariance
• The partial derivatives of the providers must be consistent with the initial covariance, i.e. must have the same date, frame, orbit type and position angle.

Method Detail

getMultiOrbitalCovariance

public MultiOrbitalCovariance getMultiOrbitalCovariance(AbsoluteDate date)
                                                 throws PatriusException

Getter for the MultiOrbitalCovariance at the provided date.

Specified by:

getMultiOrbitalCovariance in interface MultiOrbitalCovarianceProvider

Parameters:

date - The date at which the multi orbital covariance is wanted

Returns:

the multi orbital covariance at the provided date

Throws:

PatriusException - if multi orbital covariance cannot be computed at the given date

getOrbitalCovarianceProvider

public OrbitalCovarianceProvider getOrbitalCovarianceProvider(int index)

Getter for an orbital covariance provider extracting information from this multi orbital covariance.

Specified by:

getOrbitalCovarianceProvider in interface MultiOrbitalCovarianceProvider

Parameters:

index - The index of the spacecraft to be extracted

Returns:

the orbital covariance provider of the required spacecraft
