Method Details

getIcrfAlignedFrame

Frame getIcrfAlignedFrame()

Get the body centered ICRF aligned frame. For example, for Earth this would return GCRF.

Returns:

body centered, ICRF aligned frame.

Since:

14.0

getInertiallyOrientedFrame

Frame getInertiallyOrientedFrame()

Get an inertially oriented, body centered frame.

The frame is always bound to the body center, and its axes have a fixed orientation with respect to other inertial frames.

Returns:

an inertially oriented, body centered frame

getBodyOrientedFrame

Frame getBodyOrientedFrame()

Get a body oriented, body centered frame.

The frame is always bound to the body center, and its axes have a fixed orientation with respect to the celestial body.

Returns:

a body oriented, body centered frame

getName

String getName()

Get the name of the body.

Returns:

name of the body

getGM

double getGM()

Get the attraction coefficient of the body.

Returns:

attraction coefficient of the body (m³/s²)
