Unformatted text preview: NS that represents a sequence of two rotations: a. a copy of the n set is rotated about by an angle α to produce set 2 ˆ n c . b. then a copy of the c set is rotated about by an angle ε to produce set 3 ˆ c s . 3. Using the data in problem 1, find the angle between the satellite’s 2-axis and the 2 ˆ b Newtonian 3-axis at the time that these data were transmitted. 3 ˆ n 4. Show that for a sequence of infinitesimal rotations d θ about the 1-axis and d φ about the 3-axis, the final DCM is independent of the rotational order. Hint: use small-angle approximations for sin and cos. Remember that the product of two infinitesimal quantities → 0....
