Method Detail

getFrame

Frame getFrame()

Get the frame of the central body.

Returns:

frame of the central body.

Since:

6.0

getDensity

double getDensity(AbsoluteDate date,
                  Vector3D position,
                  Frame frame)
           throws OrekitException

Get the local density.

Parameters:

date - current date

position - current position in frame

frame - the frame in which is defined the position

Returns:

local density (kg/m³)

Throws:

OrekitException - if date is out of range of solar activity model or if some frame conversion cannot be performed

getDensity

<T extends RealFieldElement<T>> T getDensity(FieldAbsoluteDate<T> date,
                                             FieldVector3D<T> position,
                                             Frame frame)
                                      throws OrekitException

Get the local density.

Type Parameters:

T - instance of RealFieldElement

Parameters:

date - current date

position - current position in frame

frame - the frame in which is defined the position

Returns:

local density (kg/m³)

Throws:

OrekitException - if date is out of range of solar activity model or if some frame conversion cannot be performed

getVelocity

default Vector3D getVelocity(AbsoluteDate date,
                             Vector3D position,
                             Frame frame)
                      throws OrekitException

Get the inertial velocity of atmosphere molecules.

By default, atmosphere is supposed to have a null velocity in the central body frame.

Parameters:

date - current date

position - current position in frame

frame - the frame in which is defined the position

Returns:

velocity (m/s) (defined in the same frame as the position)

Throws:

OrekitException - if some conversion cannot be performed

getVelocity

default <T extends RealFieldElement<T>> FieldVector3D<T> getVelocity(FieldAbsoluteDate<T> date,
                                                                     FieldVector3D<T> position,
                                                                     Frame frame)
                                                              throws OrekitException

Get the inertial velocity of atmosphere molecules.

Type Parameters:

T - instance of RealFieldElement

Parameters:

date - current date

position - current position in frame

frame - the frame in which is defined the position

Returns:

velocity (m/s) (defined in the same frame as the position)

Throws:

OrekitException - if some conversion cannot be performed
