OpenAstroTracker: 3D Printed DSLR Tracking Mount may be useful for Antennas Too

OpenAstroTracker is a recently published open hardware 3D printed tracking mount designed to move DSLR cameras for astrophotography. The mount supports heavy long lenses, so we think that this mount could also have the ability to move long directional antennas for satellite tracking. It could also be interesting to modify it for automatic aircraft photography, similar to what we've seen in this previous post where a Raspberry Pi camera on a pan-tilt mount was used with ADS-B data from an RTL-SDR to track aircraft in the sky with the camera.

The 3D printer files are available on Thingiverse, and the mechanical and electronics build guide, and Arduino code is available on GitHub. The build seems to be quite a bit easier compared to a SatNOGS rotator which is another 3D printed open hardware rotator, but it is yet to be seen what sort of antenna sizes it could rotate.

    Stick a circularly polarized antenna in there. My concern is that can this rotator handle non-equatorial movement? I’ve never used an equatorial mount so I’m not really sure how they work.

    I don’t think this would work too well with some antennas. As the mount moves it would change the polarization of the antenna. Sof
