Nope, far more accurate internal systems. This was recently brought up on secret projects, commercial RLGs can provide the same or better accuracy than GPS for munitions like GMLRS and GL-SDB now, the use of GPS is just a legacy of the era they were fielded in.
Nope. The RLGs themselves can deliver accuracy of 0.0035deg/hour, which over a 150km, <10 minute flight for GLSDB works out to <1.5m error and probably less than half that for GMLRS. It's probably be even cheaper than GPS too, and unjammable.
tan (0.0035deg/hr) x 150,000m x (10/60)hrs = 1.5m
A 2S7 is 10.5m long and 3.4m wide, 1.5m off centre is still a direct hit.
And that's just a crappy $1000 commercial system. Even more accurate systems were produced even 40 years ago, they were just prohibitively expensive back then.

^That equates to only 1.8m over a 14,000km, 30 minute flight!
These days, within the budget of a hypersonic missile, you could likely spec. a system with similar accuracy for $100k.
