Seems like quite a gizmo. I have been using WXtrack for years. The serial port will control a host of alt/az mounts for dishes and arrays.
I have a 1.2 meter dish with an affixed VHF/UHF Yagi and it can follow such as ISS, AMSAT and others.
The prerequsite is keeping the TLEs up to date.
I guess if you wanted to go portable or mobile, this little box would come in handy.
