TVRO ASSISTANT gives you two of the most important calculations for aligning a satellite dish antenna; the look angle and the dish focal length. The only adjustment that this program will not calculate is "declination." Without getting too technical, declination changes depending on how far north (or south) of the equator you are. Most dish antennas, when purchase, are adjusted for the proper declination. If you purchase a dish from mail order or a home shopping channel, instructions will probably be provided for setting the proper declination. A chart generally shows what adjustment is needed for the latitude of your dish.
