I mentioned polar orbits earlier and that's because they're a somewhat degenerate case here. In between those points your normal direction will swing through north or south. There's exactly two spots in your orbit where orbit ±normal will be 30 degrees from north and that's at the ascending and descending nodes and at one node you'll be pointing east of north and the other will have you pointing west of north. If you're in an inclined orbit, there is no one reference spot on the navball for orbit normal, you kind of have to guess by watching very closely for when the prograde and retrograde markers switch sides (this can be tricky because they're mostly hidden by the edges of the navball).įor example, you can't simply aim 30 degrees east of north if you're in an orbit that's inclined 30 degrees from equatorial. In an equatorial orbit, pointing north along the horizon on the navball is orbit normal. The problem is, there's no clear indication on the navball of the normal direction except in equatorial orbits (and to a slightly more limited extent in polar orbits as well). Typically when docking you point everything in the north-south direction, because that's orbit normal and anti-normal (so it doesn't change throughout your orbit, whereas the radial/anti-radial and prograde/retrograde directions rotate as you move through your orbit). AFAIK there is always a 'right way', which is pointing to the orbit normal. Doing all this in a non-equatorial orbit seems to my limited understanding to be the very same, just at an inclination (making the navball harder to read, but I don't see how any ambiguity would come into it, making it impossible). Docking like this is perfectly achievable just looking at the current navball, and I guess with a bit of practice it's possible to do the approach this way too.). I suspect you could calculate the rotation of the docking port by where you are in the orbit. But I think that as long as the target port is pointing to the orbit normal, and you approach from there, oriented towards the orbit anti-normal, it's a matter of translating so you line up the pink target on your nose and then close the distance. I've been trying to avoid external views and use mostly IVA for approach and docking, and I think I'll get it eventually (I'm sticking to equatorial orbits at the moment tho). If you're not in an equatorial orbit, there is no "right way".Ĭould you elaborate on this a bit? Why is a non-equatorial orbit any different, doesn't it just tilt everything to the inclination?
