Listening to the radio chatter in Sword of Annihilation, the Excalibur personnel calculate the point of impact before each beam. Using radars to spot the aircraft, the laser is fired upon the location the plane is crossing through, a.k.a. probability calculation.

We have never seen the satellites or how they are controlled. But it is likely a mirror ever moving according to probability calculation.
