15 years ago, when we first started with a satellite system, we had to rely on a compass for a rough aim and then I used a signal strength indicator for the fine adjustment. Nowadays, it is unusual to turn up at a campsite and not find someone else who has already set up their satellite dish. By taking a look at how their dish is adjusted, I copy their setup and this saves having to use a compass. It's then relatively easy to sweep the sky from east to south (or vice versa) until you get the best signal. The biggest problem, especially if you are going far north or far south in Europe is to get the elevation (the up/down setting) right, but that's usually just a matter of fine adjustment once you've got an optimal azimuth (East/South) setting.
