Constructor Detail

TroposphericDSConverter

public TroposphericDSConverter(SpacecraftState state,
                               int freeStateParameters,
                               AttitudeProvider provider)

Simple constructor.

Parameters:

state - regular state

freeStateParameters - number of free parameters, either 3 (position) or 6 (position-velocity)

provider - provider to use if attitude needs to be recomputed

Method Detail

getFreeStateParameters

public int getFreeStateParameters()

Get the number of free state parameters.

Returns:

number of free state parameters

getState

public FieldSpacecraftState<DerivativeStructure> getState(DiscreteTroposphericModel tropoModel)

Get the state with the number of parameters consistent with tropospheric model.

Parameters:

tropoModel - tropospheric model

Returns:

state with the number of parameters consistent with tropospheric model

getParameters

public DerivativeStructure[] getParameters(FieldSpacecraftState<DerivativeStructure> state,
                                           DiscreteTroposphericModel tropoModel)

Get the tropospheric model parameters.

Parameters:

state - state as returned by getState(DiscreteTroposphericModel)

tropoModel - tropospheric model associated with the parameters

Returns:

tropospheric model parameters
