We say 'No problems'! SARCTRAC helps kids spend more time listening to signals from space, receiving data or pictures and even communicating with others via satellites. So, we designed SARCTRAC to be quick and easy for the kids to set up, and now, it does all the work for them. Setting up an automatic tracking system, with a commercial antenna rotator is both tricky and expensive. Tracking a satellite by hand, while trying to tune an Amateur Radio transceiver for a typical 10-minute overhead pass, is a real chore for kids. “Of course, you can.” But the reality is that satellites move so fast that their position and radio frequency is constantly changing. It is really exciting when the kids hear their first satellite and then realise where it is. It is a bit like fishing in the sky and just as challenging.

To make friends with a satellite you first have to know when and where it will be point a small, directional antenna at it and use an Amateur Radio transceiver to listen or talk through it.
