Constructor Detail

TabulatedLofOffset

public TabulatedLofOffset(Frame inertialFrame,
                          LOFType type,
                          List<TimeStampedAngularCoordinates> table,
                          int n,
                          AngularDerivativesFilter filter)

Creates new instance.

Parameters:

inertialFrame - inertial frame with respect to which orbit should be computed

type - type of Local Orbital Frame

table - tabulated attitudes

n - number of attitude to use for interpolation

filter - filter for derivatives from the sample to use in interpolation

Method Detail

getTable

public List<TimeStampedAngularCoordinates> getTable()

Get an unmodifiable view of the tabulated attitudes.

Returns:

unmodifiable view of the tabulated attitudes

getAttitude

public Attitude getAttitude(PVCoordinatesProvider pvProv,
                            AbsoluteDate date,
                            Frame frame)

Compute the attitude corresponding to an orbital state.

Specified by:

getAttitude in interface AttitudeProvider
