Attitude represented as a quaternion.
![]() | First element of the quaternion (and of its vector part) representing orientation between two sets of axes. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then Q1=nx sin(A/2). |
![]() | Second element of the quaternion (and of its vector part) representing orientation between two sets of axes. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then Q2=ny sin(A/2). |
![]() | Third element of the quaternion (and of its vector part) representing orientation between two sets of axes. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then Q3=nz sin(A/2). |
![]() | Fourth element of the quaternion (its scalar part) representing orientation between two sets of axes. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then Q4=cos(A/2). |
