This came up in a game:

If I land on the station and want to shoot it (armed/unarmed), is the shot obstructed?

We figured no, but avoided the problem entirely by me landing next to the station instead of on top.

But the question still stands.

In the Corellian Conflict Campaign book on page 3, under line of sight, last sentence.

A ship or squadron that is overlapping a station cannot declare an attack against that station.

Awesome! Thanks, missed that one.
