It is then only necessary to move to the correct latitude and fall into alignment with the NED system by means of an additional left-handed rotation around the y-axis, through the latitude angle. 6-22) The rotation to a geocentric system is found similarly, except that geocentric latitude is used in place of geodetic. 6-23) Cc∕eci = ⎢ −s???? ⎢ ⎥ ⎣−c???? c???? −c???? s???? −s???? ⎦ Gravitation and Gravity The term gravitation denotes a mass attraction effect, as distinct from gravity, meaning the combination of mass attraction and centrifugal force experienced by a body constrained to move with Earth’s surface.
In time ????t, p2 − p is given by . p2 − p = b p ????t + (????b∕a × p)????t Dividing by ????t and taking the limit as ????t → 0 give a. 4-1 A vector derivative in a rotating frame. 4-2) is sometimes called the equation of Coriolis (Blakelock, 1965) and will be an essential tool in developing equations of motion from Newton’s laws. It is much more general than is indicated above and applies to any physical quantity that has a vector representation. The derivatives need not even be taken with respect to time.
5-1 shows a point P with position vector p moving with respect to two frames Fa and Fb , in relative motion, and with fixed points O and Q, respectively. Suppose that we wish to relate the velocities in the two frames and also the accelerations. We must first relate the position vectors shown in the figure and then take derivatives in Fa to introduce velocity (we are arbitrarily choosing Fa to be the “reference” frame): pP∕O = pQ∕O + pP∕Q a. . 5-1 21 Fb Fa Velocity and acceleration in moving frames.
