7) the ned system is fixed in the Earth as the reference frame, and the relative angular velocity is that of the body with respect to Earth. In the case of the more general 6-DoF equations the ned system moves over the Earth, underneath the body, and we must define an abstract reference frame which has its own angular velocity with respect to the Earth frame (determined by latitude and longitude rates). The coordinate transformations are . frd ????b∕r ⎛ ⎡0. ⎤ ⎡0⎤⎞ ⎡????⎤ = ⎢ 0 ⎥ + C???? ⎜ ⎢???? ⎥ + C???? ⎢ 0 ⎥ ⎟ ⎜⎢ ⎥ ⎢ .
Thus, at geodetic height h, the 28 THE KINEMATICS AND DYNAMICS OF AIRCRAFT MOTION geographic system North component of velocity, vN , over Earth is related to latitude rate by . 6-6) vN = (M + h) ???? The prime vertical radius of curvature, N, is the radius of curvature in a plane perpendicular to the meridian plane and containing the prime vertical (the normal to the spheroid at the pertinent latitude). 6-3, and N is the distance to the ellipse (two parts of N are shown in the figure). Note that N occurs in almost all of the geodesy calculations that we will use.
Velocity), then we expect its derivative to be independent of 17 ROTATIONAL KINEMATICS translation, and the changes in length and direction come from the motion of the tip of p relative to its tail. , a position vector) in some frame, its derivative in that frame is a free vector, corresponding to motion of the tip of p. 2-5a) gives ????u ≈ −sin(−????????)n × u ≈ (n × u) ???????? . Now divide by ????t, take the limit as ????t → 0, and define the vector ???? ≡ ???? n, giving . 4-1) This equation relates the translational velocity of the tip of the constant-length bound vector u to the vector ????.
