In short it has none. There are no permament land marks - no distant stars or pulsars to accurately fix your position. The Hyper limit gives no indication where it is without trying to translate down. If you miss - and if you're lucky, you'll just bounce off of it or translate on the far side of the star from where you intended. All you have to go by is the Hyper log - which is essentially a computer record of what you perceive your ship did after you left the last known reference point. We know there are lesser and greater grav currents, eddies and sheres in Hyper space - the grav waves are just the biggest.
So you want to stalk Planet X. You plug where you want to go into the computer with the Hyper log and it stops you where you "think" the translation point is (Hyper logs are pretty good - you are probably close).
But did you completely stop? How do you know? If you have any velocity you didn't account for, you are still moving - even if just milimeters per second. (and let's face it, if you don't know exactly where you would translate, you have to have SOME velocity variable you have only accounted for in your error factor).
If there is a gentle current in that area of hyper, you also will soon be pulled off that point. The more time you spend in theat one "place", the longer any initial velocity and any currents will be pulling you off the intended point.
That's one of the reasons for the "Paul Revere" destroyer for Hyper Defenders - it is also a beacon for the entry locus for the fleet to use. If not, they would have no idea where they were relative to the hyperlimit to translate down.
Considering that merchant shipping seems to usually arrive roughly at the right spot and rarely seems to get turned into goo by trying to cross the alpha wall at the wrong spot I'm going to say that this is pretty much a solved problem in the honorverse. They have been doing this for centuries and have a pretty good idea how to navigate in hyper.
The reason you send a vessel to the alpha side to summon help is because there is no communication between real-space and alpha-space without someone carrying a message between them. It isn't to show them where to go, it's to tell them that they need to go.
