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)

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)

getDensity

<T extends CalculusFieldElement<T>> T getDensity(FieldAbsoluteDate<T> date,
                                                 FieldVector3D<T> position,
                                                 Frame frame)

Get the local density.

Type Parameters:

T - instance of CalculusFieldElement

Parameters:

date - current date

position - current position in frame

frame - the frame in which is defined the position

Returns:

local density (kg/m³)

getVelocity

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

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)

getVelocity

default <T extends CalculusFieldElement<T>> FieldVector3D<T> getVelocity(FieldAbsoluteDate<T> date,
                                                                         FieldVector3D<T> position,
                                                                         Frame frame)

Get the inertial velocity of atmosphere molecules.

Type Parameters:

T - instance of CalculusFieldElement

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)
