And, while I'm in the bad habit of replying to myself and just for the
record: you can't get a fix with just the angle between two objects
and no azimuth. The angle only gives you a circle of position (or to
be fully correct two possible circular arcs of position except where
you have a transit and it becomes a line of position). With just
angles between objects you need three to get a 2d fix (unless you have
transits where you only need two). But you knew that

Well, normally when you are doing it you take the angle between two
points a known distance apart...

That still gives you an arc of position, not a fix.
