Can you be more specific as to the issue you are having.
OK so you have Requested docking from station and entered OK.
Basic rules: come in through the slot slowly until you are used to it, Look for the designated pad number.
If you cant find it, look at the tiny radar indicator to the Left and just above your main scanner. The blue dot will indicate if its to left, right above or below you.
If its not directly in front and below you, then roll left or right to have it appearing in front of you so you are lined up with the pad or the numbers.
Move toward the pad slowly, you must be FACING the BACK of the station when you are touching down. If you are not facing the back wall you are going the wrong way.
The Bay number is at the BACK of the pad. You approach the pad from the side furthest away from the PAD number and come in over the top of the pad.
Lower the gear as soon as you are through the slot, This slows you down and adds safety by disabling you boost. You dont want to be a splat mark on the back wall.
Come in well below the number close to the pad for starters facing the landing tower that is always just in front of the numbers and slow down.
When you are above the pad and low down, you get an indicator showing your ship above the pad. (if you are too high, no landing indicator even when you are above the pad)
Its really important that you have some buttons or keys mapped to your manouvering thrusters. Use these to slide left or right, forward or back for starters.
Then you will see the position on the pad in the scanner, once all in the center it will change colour. Lower the ship gently.
Remember although you can land like you would a plane, that not how you would normally do it.
Use main engines to get close to pad and very low down SLOWly and parallell to the pad facing the back of the station. Once you get the landing radar, you then use your maneuvering thrusters, no more Pitching and rolling.
I have mentioned alot of things you dont really need when experienced but there might be a clue as to what you are missing.
Also in an outpost, there is no back of station so as you approach you adjust your approach so that the numbers are at the back of the pad and you approach the numbers from the far side. that is always the correct direction.
