Package fr.cnes.sirius.patrius.attitudes.directions

Interface Summary

Interface	Description
IDirection	This is the main interface for directions.
ITargetDirection	This interface extends Directions for the directions described by a target point.

Class Summary

Class	Description
BodyPointTargetDirection	This class extends the GenericTargetDirection to create a direction with a target which is a BodyPoint.
CelestialBodyPolesAxisDirection	This direction is the axis defined by the two poles of a celestial body.
ConstantVectorDirection	Direction described only by a vector constant in a frame
CrossProductDirection	This direction is the cross product of two directions
EarthCenterDirection	Direction to Earth body center : the central body's center is the target point.
EarthToCelestialPointDirection	Direction from Earth center to celestial point : the celestial point is the target point.
GenericTargetDirection	Direction described by a target PVCoordinatesProvider.
GlintApproximatePointingDirection	"Glint" direction pointing.
GroundVelocityDirection	Ground velocity direction.
LightAberrationTransformation	This class implements the light aberration transformation.
MomentumDirection	Direction described either: By a celestial body (the reference body of the orbit).
NadirDirection	Nadir direction.
NorthNormalToEclipticDirection	Direction towards normal of ecliptic plane as computed in GCRF.
ToCelestialPointDirection	Direction described by a celestial point: the celestial point is the target point.
VelocityDirection	Direction defined for any PVCoordinatesProvider origin by its velocity vector, expressed in a reference frame (parameter of the constructor).

Enum Summary

Enum	Description
ITargetDirection.AberrationCorrection	Enumerate for the aberration corrections to apply, see aberration corrections for more details about corrections CN, CN+S, XCN and XCN+S referred here under.
ITargetDirection.SignalDirection	The signal propagation direction.
