    I used to use MrOrbit. That has a function giving lat/long.

    Unless you just want the exercise, software already exists.

    As mentioned before, you don't need lat/long. You do want azimuth/
    elevation. The best way to do that is use a prediction program
    like HIGHFLY. You may then make predictions at a moment's notice.
