Build your own antenna rotator/satellite tracking device

Arduino TeamDecember 5th, 2017

After finding that purchasing a tracking device for his satellite dish would be quite expensive, YouTuber “Tysonpower” decided to simply build one himself. What he came up is an assembly made with 3D-printed parts and extruded aluminum that uses a pair of NEMA23 stepper motors for movement.

While it doesn’t quite work with the dish itself due to its offset weight, the concept was successfully used to track weather satellites using a VHF Yagi antenna.

Control is provided via an Arduino Nano, which interfaces with a computer over USB serial that provides satellite information. You can check it out in the video below, and find more details in the project’s write-up.
