Yet.. I still don't see how the ship can apply its "transversal velocity" to out maneuver the weapons from that data...
Some of you are focusing on my "pinpointed 3+ turns away." and totally ignore the "transversal velocity" part.
But by pinpointing, I or We didn't exactly mean they engaged in fighting. But rather that the station has according to your data.
Enough time to align their weapons, ready the shields, make some tea and get some nookie a few times over....
In short the only way the ship could have applied "transversal velocity", is using the element of surprise.
Yet the only surprise, is that the station got destroyed by a strong wind or fart
While it is true that a station should have hours to days of warning of the approach of hostile vessels detected 3 tiles away, it is not necessarily true that the information gathered is sufficiently useful to engage the vessels upon reaching effective weapon ranges. We know that Galactic Civilizations hyperdrives work by warping space in some way, and perhaps this prevents the collection of sufficiently accurate position and velocity information for use in targeting an approaching vessel - after all, we don't know if the sensor technology within the game is able to distinguish between a ship moving at a speed of 0.1c while warping distances by a factor of 20 and a ship which is moving at a speed of 0.2c while warping distances by a factor of 10, or if we can distinguish either of those ships from one moving at 10 mph and warping distances by a factor of 1.34X10^8. Nor do we know how accurately the map-level sensors can determine the distance and direction to a detected target - for all we can tell from the map, the long-range sensors in the Galactic Civilizations universe may actually have worse angular resolution the closer a target comes to the sensor, as the direction in which a vessel on an adjacent tile can be found is known no more accurately than to within one sixth of a sphere (or perhaps a circle) by looking at the game map, but the direction to a target two tiles distant is known to within about one-twelfth of a sphere (or perhaps a circle), and so on, and based on the information within the game it would not be possible to say with any certainty whether this is a limitation of the in-game representation or a limitation of the sensor or an advantage of warping space for effectively superluminal travel rates, and, assuming that this is a limitation of the sensor or an advantage of hyperdrives, we don't know if it's possible to accurately back out the necessary information based on what the sensors detect, and even if the effective weapon ranges are as low as a few hundred kilometers even small errors in determining the direction to a target can turn shots into clean misses.
We also know that all (or at least almost all) map-level movement is performed while the hyperdrive is engaged, but we do not know how close ships come to planets, stations, and other ships before disengaging the hyperdrive, nor do we know how warped space in the Galactic Civilizations universe interacts with projectiles and electromagnetic radiation (e.g. lasers or radar pulses) attempting to reach a target producing the distortion effect. We don't know if ships with hyperdrives engaged are effectively immune to detection by the kinds of sensors used for combat targeting or if ships are forced to disengage their hyperdrives long before they reach engagement ranges because emissions from targeting radars crossing the spatial distortions generated by active hyperdrives at close to combat ranges hit whatever is inside the distortion with the force of a supernova (though this last is likely not the case). We don't know how quickly ships move from the range at which they disengage hyperdrives to combat ranges, other than that the time period in which this happens is no greater than perhaps a third or a half of the time period represented by 1 move action, or if the ships can make use of their hyperdrives over short (but greater than combat) ranges to screw with targeting. We don't know when evasive maneuvers, spoofing, jamming, or other ways to evade weapons fire becomes effective; possibly ships intent on engaging a target can approach under sufficiently heavy jamming to prevent a target's sensors from providing an adequate firing solution until both sides are well within the effective ranges of the weapon systems under ideal circumstances, perhaps the station's weapons have a lower effective range against the attacker than the attacker's weapons do against the station (not terribly unlikely, as the station is a large and relatively immobile target whereas the attacker is probably smaller and is likely designed for greater maneuverability than the station).
We simply do not know enough about the capabilities of the weapons, the sensors, the ships, and the stations in Galactic Civilizations to judge whether or not a station can make use of its knowledge that a hostile ship is approaching from a point 3 tiles away to prepare a warm welcome for that ship, nor do we know enough about how hyperdrives work (or are used) in Galactic Civilizations to say whether or not real-world sensors could be used to prepare the same warm welcome on final approach to combat ranges. Without knowing this kind of information, we really cannot say whether or not a station that detects an approaching hostile ship has 3 nanoseconds or 3 days to point the guns in the right direction with enough accuracy to hit the approaching vessel, or even whether or not it has the information to do more than put "General Quarters 2 o'clock Tuesday" on the schedule.
