Track

public Track(Boresight boresight,
     PhaseAngle phaseAngle,
     TargetTrack target,
     OffsetAngles oAngles,
     OffsetRefAxis oRefAxis)

Creates an Attitude where the target is given by a solar system object or landmark.

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 - solar system object or landmarks defined in the PDFM

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
