Nevermind. I "pasted" (manually typed, hah!) bits of that code into kOS and it was sh.itting itself on the geoposition parameters. I've successfully done it multiple times since, so chalk that one up to exhaustion from playing too much KSP, I guess. As for the arctan2 thing, that was, sadly several different web searches returning the same incorrect equation for something not relevant here. As long as you look out for radians/degree thing, it seems to also be ok. I need sleep.
