Constructor Detail

TargetDir

public TargetDir()

Creates a targetDir Direction vector referenced to CG2Sun Direction vectors can be defined by referencing to direction vectors that were previously defined and got a name assigned.

TargetDir

public TargetDir(java.lang.String frame,
         float longitude,
         float latitude)

Creates a targetDir fixed direction vector expressed in spherical coordinates For spherical coordinates the element must contain the child elements and . The cartesian components of the vector are (cos(lat)*cos(lon), cos(lat)*sin(lon), sin(lat)). The unit in which longitude and latitude are written must be deg. The frame attribute specifies relative to which frame the direction vector is defined. Possible values are SC, EME2000 and CG.

Parameters:

frame - The frame where this vector is expressed (SC,EME2000,CG)

longitude - Longitude expressed in deg.

latitude - Latitude expressed in deg.

TargetDir

public TargetDir(PointingElement pm)

TargetDir

public TargetDir(java.lang.String reference)

Creates a targetDir Direction vector referenced to another direction vector Direction vectors can be defined by referencing to direction vectors that were previously defined and got a name assigned.

Parameters:

reference - Name of the referenced direction vector

TargetDir

public TargetDir(java.lang.String frame,
         float x,
         float y,
         float z)

Creates a fixed targetDir direction vector expressed in cartesian coordinates For cartesian coordinates the element must contain the child elements and that contain fixed numbers specifying the components (that must not all be zero). The direction vector corresponds to the normalization of the vector.

Parameters:

frame - The frame where this vector is expressed (SC,EME2000,CG)

x - The x component of this vector

y - The y component of this vector

z - The z component of this vector

TargetDir

public TargetDir(java.lang.String frame,
         java.lang.String unitLongitude,
         float longitude,
         java.lang.String unitLatitude,
         float latitude)

Creates a fixed targetDir direction vector expressed in spherical coordinates For spherical coordinates the element must contain the child elements and . The cartesian components of the vector are (cos(lat)*cos(lon), cos(lat)*sin(lon), sin(lat)). For spherical coordinates the attribute units must be provided and must contain a dimension of an angle. The frame attribute specifies relative to which frame the direction vector is defined. Possible values are SC, EME2000 and CG.

Parameters:

frame - The frame where this vector is expressed (SC,EME2000,CG)

unitLongitude - Unit in which the longitude is expressed

longitude - Longitude

unitLatitude - Unit in which the latitude is expressed

latitude - Latitude

TargetDir

public TargetDir(java.lang.String origin,
         java.lang.String target)

Creates a targetDir direction vector based in Origin and Target This representation is used to define a direction vector from two state vectors. Because state vectors are always defined relative to inertial frame, the resulting direction vector is defined relative to inertial frame.

Parameters:

origin - Origin State vector

target - Target State vector

TargetDir

public TargetDir(java.lang.String axis,
         java.lang.String rotationAxis,
         float rotationAngle)

Creates a targetDir rotated Direction Vector This representation allows to define a direction vector by right-handed rotation of the direction vector axis around rotationAxis by the angle rotationAngle. The axes axis and rotationAxis must both be defined either relative to SC or inertial frame.

Parameters:

axis - The axis that this vector reference

rotationAxis - Rotation axis of the vector

rotationAngle - Rotation angle. It must be expressed in deg.

TargetDir

public TargetDir(java.lang.String axis,
         java.lang.String rotationAxis,
         java.lang.String rotationAngleUnit,
         float rotationAngle)

Creates a targetDir rotated Direction Vector This representation allows to define a direction vector by right-handed rotation of the direction vector axis around rotationAxis by the angle rotationAngle. The axes axis and rotationAxis must both be defined either relative to SC or inertial frame.

Parameters:

axis - The axis that this vector reference

rotationAxis - Rotation axis of the vector

rotationAngleUnit - Unit in which the angle of rotation is expressed

rotationAngle - Rotation angle
