Description :

This is the interface for inertia models that can provide the mass, mass center and inertia matrix of the whole satellite.

Field Summary

Fields inherited from interface org.orekit.propagation.MassProvider

MASS

Method Summary

Matrix3D	getInertiaMatrix(Frame frame, AbsoluteDate date) Getter for the inertia matrix of the spacecraft, expressed with respect to the MASS CENTER in a given frame.
Matrix3D	getInertiaMatrix(Frame frame, AbsoluteDate date, Vector3D inertiaReferencePoint) Getter for the inertia matrix of the spacecraft, once expressed with respect to a point that can be different from the mass center.
Vector3D	getMassCenter(Frame frame, AbsoluteDate date) Getter for the mass center.

Method Detail

getMassCenter

Vector3D getMassCenter(Frame frame,
                       AbsoluteDate date)
                       throws OrekitException

Getter for the mass center.

Parameters:

frame - the expression frame of the mass center position

date - the current date (unused for simple the model)

Returns:

the mass center position vector

Throws:

OrekitException - if a problem occurs during frames transformations

getInertiaMatrix

Matrix3D getInertiaMatrix(Frame frame,
                          AbsoluteDate date)
                          throws OrekitException

Getter for the inertia matrix of the spacecraft, expressed with respect to the MASS CENTER in a given frame.

Parameters:

frame - the expression frame of the inertia matrix

date - the current date (unused for simple the model)

Returns:

the inertia matrix

Throws:

OrekitException - if a problem occurs during frames transformations

getInertiaMatrix

Matrix3D getInertiaMatrix(Frame frame,
                          AbsoluteDate date,
                          Vector3D inertiaReferencePoint)
                          throws OrekitException

Getter for the inertia matrix of the spacecraft, once expressed with respect to a point that can be different from the mass center. This point must be defined in the reference frame of expression of the matrix.

Parameters:

frame - the expression frame of the inertia matrix

date - the current date (unused for simple the model)

inertiaReferencePoint - the point with respect to the inertia matrix is expressed (in the reference frame)

Returns:

the inertia matrix

Throws:

OrekitException - if a problem occurs during frames transformations
