Amsats and Hamsats gets right into the techniques you will need for working amateur radio stations through amateur radio satellites, then it moves on to listening, or watching, signals from satellites. There are chapters answering questions like, "how do satellites stay in orbit" and "why are they so expensive to launch?" Followed by sections about the history of amateur radio satellites, the mathematics governing orbits, different types of satellite and their orbits. It covers the equipment you need, to track and use the amateur satellites and some of the satellite tracking software that is available. There are detailed sections covering feeders, Masthead preamplifiers, antenna systems and automated rotator control. There are the details of FUN cube Satellites, Weather Satellites and even the International Space Station. If you want to know the art of the possible and what satellites ae available, where they are, new ones that are planned and even the bands you can operate. There is much more besides, as Amsats and Hamsats provides the ultimate guide to operating satellites.
Amsats and Hamsats provides in its impressive 368 pages a great value guide to this stimulating and challenging area of amateur radio activity. If you want to get started or are already an experienced operator you will find something of value in these pages.
