The projectiles fired by the railgun leave the atmosphere and are GPS guided.
Yeah, did you look into what "GPS guided" means here? Its not what you think.
I think they are trying to crack a joke.
Considering that the escape velocity on Earth's surface is ~11200m/s and railgun speeds tend to be around 5000m/s^[at least in Wikipedia, all stated values are < 5km/s] (i.e. less than half) and also that the escape velocity would be considering a normal direction whereas railgun usage tends to be more tangential (from the surface of the Earth), I wouldn't be expecting any casual leave-the-atmosphere scenarios.
As far as guided systems go, last I checked there wasn't enough leeway to add any electronic or mechanical elements in the projectiles.
