As long as the orbit isn't changing, pointing the antenna is not hard and can be done by hand. I've done it with a handheld yagi antenna and the ISS, which has a 90-minute orbit (and an amateur radio repeater). I used a computer program to find the next overhead transit, paying attention to start & end times and start & end azimuth. Then used a watch to know where to point the antenna during the transit: at the horizon at the start, overhead halfway through the transit, at the opposite horizon at the end. Transits were 5-10 minutes so there's plenty of time to move the antenna.
