This graphical look angle calculator will be included in an upcoming antenna applications online training course.  It is an online, updated version of the classic physical slide rule chart from the 1990s, in which ground station azimuth and elevation could be read off curves printed on a transparent cursor, which you move to choose your target satellite.  

This utility goes a couple of steps further: not only does it show az and el curves, it shows curves of constant skew angle (which is the horizontal pol angle) from the site; you can drag the earth station around and watch the calculations change; and you can view what the GEO arc and the target satellite look like from the perspective of the earth station. Try it out live below!  Be sure to click the three check boxes (az, el, and pol/skew).
