Inertial

public Inertial(Boresight boresight,
        PhaseAngle phaseAngle,
        TargetInert target,
        OffsetAngles oAngles)

Creates an Attitude where the boresight is aligned with a fixed vector given relative to inertialframe.

Parameters:

boresight - Vector defined in SC frame that shall be pointed to the target

phaseAngle - Rule that fixes the degree of freedom around the boresight.

target - Fixed vector defined relative to inertial frame

oAngles - OffsetAngles

Inertial

public Inertial(Boresight boresight,
        PhaseAngle phaseAngle,
        TargetInert target,
        OffsetAngles oAngles,
        OffsetRefAxis oRefAxis)

Creates an Attitude where the boresight is aligned with a fixed vector given relative to inertialframe.

Parameters:

boresight - Vector defined in SC frame that shall be pointed to the target

phaseAngle - Rule that fixes the degree of freedom around the boresight.

target - Fixed vector defined relative to inertial frame

oAngles - OffsetAngles

oRefAxis - defines together with the boresight two axes in SC frame around which the rotations are performed. offsetRefAxis is of type direction vector. In the following these axes are called offset-x-axis and offset-y-axis. The offset-y-axis is the unit vector along the cross product of boresight and offsetRefAxis. The offset-x-axis is defined such that offset-x-axis, offset-y-axis and boresight form a right handed orthogonal frame. If for offsetRefAxis a direction vector is specified that is defined relative to inertial frame then it is converted to SC frame by using the basic pointing without offset rotations. The resulting SC attitude with offset rotations is given by the basic pointing rotated right handed first around the offset-x-axis by minus the y-angle and then a right handed rotation around the offset-y-axis by the x-angle. This convention is chosen because a positive x and y-angle rotate the boresight towards the offset-x-axis and y-axis, respectively
