LEO Satellite Rotator (elevation / azimuth)

thingiverse

A cutting-edge 3D printed azimuth/elevation antenna rotator for precision tracking of low Earth orbit satellites. The poles utilized in this design are high-quality 32mm plastic waste pipe (initially I used 40mm pipe but switched to the current setup midway through, which is why there are slotted bearing inner spacers). The bearings chosen were robust 40mm inside diameter/68mm outside diameter (NTN SNR 6008-ZZ Deep Groove Ball Bearing). This innovative rotator was created for use in a home loft environment, and I do not recommend using it outdoors. My setup is controlled by an ESP32 microcontroller and cost-effective stepper drivers. GPredict software connects directly to the ESP32 via Wi-Fi. If you need access to the firmware, please let me know; although the programming may be basic, it gets the job done. I am fairly certain that I used SatNogs components (worm gear and the cog that surrounds the poles) for this project. Further details will follow shortly, so please do not hesitate to get in touch if you have any questions.
