The comments: You are leaving the biggest element out of the picture, the Earth's daily rotation. The sequence is precession and nutation, daily rotation, and polar motion. Now the questions: Polar motion is rather small; do you really need it? What kind of accuracy do you need? Finally, you do not want to roll your own calculation here. It is incredibly complex; the odds are zero you'll get the calculation right. What you want is existing software such as the SOFA routines or JPL's SPICE. | |
| Jul 24, 2018 at 15:52 | comment | added | uhoh | Well, the first sentence together with the first equation (Eq. 5.1) suggests that you need to do three sequential operations. [GCRS] = $Q(t)R(t)W(t)$ [ITRS] Reading further suggests each of those may be three separate rotations. So this is going to be a lot more work than "a single formula." | |
