Constructor Detail

AbstractEncounterLOF

protected AbstractEncounterLOF(PVCoordinates other)

Constructor with PVCoordinates.

Parameters:

other - other object to create the encounter local orbital frame with (not the origin of the frame !)

AbstractEncounterLOF

protected AbstractEncounterLOF(FieldPVCoordinates<T> other)

Constructor with FieldPVCoordinates.

Type Parameters:

T - type of the field elements

Parameters:

other - other object to create the encounter frame with (not the origin of the frame !)

Method Detail

rotationFromInertial

public <T extends CalculusFieldElement<T>> FieldRotation<T> rotationFromInertial(Field<T> field,
                                                                                 FieldPVCoordinates<T> origin)

Get the rotation from inertial to this encounter local orbital frame.

BEWARE: The given origin's position and velocity coordinates must be given in the frame in which this instance has been expressed in.

Specified by:

rotationFromInertial in interface EncounterLOF

Type Parameters:

T - type of the field elements

Parameters:

field - field to which the elements belong

origin - position-velocity of the origin in the same inertial frame as the one this instance has been expressed in.

Returns:

rotation from inertial to this encounter local orbital frame

rotationFromInertial

public Rotation rotationFromInertial(PVCoordinates origin)

Get the rotation from inertial to this encounter local orbital frame.

BEWARE: The given origin's position and velocity coordinates must be given in the frame in which this instance has been expressed in.

Specified by:

rotationFromInertial in interface EncounterLOF

Parameters:

origin - position-velocity of the origin in some inertial frame

Returns:

rotation from inertial to this encounter local orbital frame

getFieldOther

public <T extends CalculusFieldElement<T>> FieldPVCoordinates<T> getFieldOther(Field<T> field)

Get the field version of other's position and velocity coordinates. If the instance has been created with normal PVCoordinates, then it will build its field equivalent.

Specified by:

getFieldOther in interface EncounterLOF

Type Parameters:

T - type of the field elements

Parameters:

field - field of the elements

Returns:

field version of other's position and velocity coordinates

getOther

public PVCoordinates getOther()

Get the normal version of other's position and velocity coordinates. If the instance has been created with field FieldPVCoordinates, then it will convert it to its PVCoordinates equivalent.

Specified by:

getOther in interface EncounterLOF

Returns:

normal version of other's position and velocity coordinates
