Constructor Detail

TabulatedLofOffset

public TabulatedLofOffset(Frame inertialFrame,
                          LOF lof,
                          List<? extends TimeStampedAngularCoordinates> table,
                          int n,
                          AngularDerivativesFilter filter)

Creates new instance.

This constructor uses the first and last point samples as the min and max dates.

Parameters:

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

lof - 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

TabulatedLofOffset

public TabulatedLofOffset(Frame inertialFrame,
                          LOF lof,
                          List<? extends TimeStampedAngularCoordinates> table,
                          int n,
                          AngularDerivativesFilter filter,
                          AbsoluteDate minDate,
                          AbsoluteDate maxDate)

Creates new instance.

Parameters:

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

lof - local orbital frame

table - tabulated attitudes

n - number of attitude to use for interpolation

minDate - min date to use

maxDate - max date to use

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

Since:

11.0
