[amsat-bb] G-5500 Orientation

[Dean Maluski]

I am installing a G-5500 Elevation rotor and trying to determine
orientation of elevation with reference to software specifically
rtrcontrold for Linux but I'd suspect this would be typical to most PC
applications.
If a sat is 45 degrees above horizon should rotor control read 45 or 135
degrees on the hardware control dial?
What I'm asking is when I want to mount antenna where 90 degrees is
horizontal or vertical?
It seems natural that midway point is horizontal but midway point is 90
degrees. I don't think I ever have a reason to point antenna into the
mud so it makes most sense that midway 90 degrees is straight up??
