  org.orekit.forces.atmospheres.MSISE2000

All Implemented Interfaces:

Serializable, Atmosphere

public class MSISE2000
extends Object
implements Atmosphere

This class implements the MSIS00 atmospheric model.
It is an interface layer between the NRLMSISE00 class - adapted from Fortran - and the SIRIUS data structures.

Method Detail

getDensity

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

Get the local density.

Specified by:

getDensity in interface Atmosphere

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

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

Get the spacecraft velocity relative to the atmosphere.

Specified by:

getVelocity in interface Atmosphere

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

getSpeedOfSound

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

Get the local speed of sound.

Specified by:

getSpeedOfSound in interface Atmosphere

Parameters:

date - current date

position - current position in frame

frame - the frame in which is defined the position

Returns:

speed of sound (m/s)

Throws:

OrekitException - if some conversion cannot be performed
