It won't help. You can easily see where a dumb bomb will fall because it just falls down.
A gliding bomb flys. You can't predict how it will fly. You have to correct the trajectory during its flight.
Gliding bombs don't fly. They also fall down, gliding along the way. They're not proper aircraft but heavy dense non-aerodynamic chunks of metal and explosives with wings attached to extend their path down to Earth.
The problem of calculating their flight-path we can relate to that of another military field we've heard about, namely that of non-ballistic atmospheric re-entry for things like warhead buses or asteroids
It's not a trivial problem to work out but nonetheless a solvable one with some accuracy. After all we can witness the advent of maneuverable hyper-sonic glide vehicles such as the Avangard, which undertake maneuvers to evade missile defenses. If it wasn't theoretically possible for missile defense systems to determine their trajectories in the first place and intercept them - then there would have been no need to add maneuver capability to them; it would have been enough for them to simply glide.
And this means that an on-board aircraft computer can calculate the trajectory of a gliding bomb that it releases with good accuracy, especially if it accounts for the wind speed at the moment of release, factors in local meteorological data, and is utilizing them at a lower altitude or a higher speed; limiting the range but giving less time for error to compound until impact.
In fact the comparison I made to atmospheric reentry is merely illustrative, being rather excessive in reality. An actual gliding trajectory under ideal conditions is pretty much a straight line that you can calculate with trigonometry alone (https://www.grc.nasa.gov/www/k-12/VirtualAero/BottleRocket/airplane/glidprob.html).. which actually makes them a lot easier to work out than ballistic trajectories of any kind.
Yes both gliding bombs and hypersonic gliding vehicles will be affected by winds and turbulence but in both cases they have a huge amount of inertia minimizing this effect on account of their density and speed respectively.
