If an Excalibur projectile fails to acquire adequate GPS signal during flight, what is designed to happen to the round?

The design of the Excalibur projectile incorporates sophisticated guidance systems, including GPS for precision targeting. If the projectile is unable to acquire a sufficient GPS signal during its flight, it is engineered to continue on its pre-planned trajectory to the ballistic impact point. However, it does so without arming, which means that upon impact, it would not detonate as a live projectile. This mechanism is crucial in preventing unintended detonation and minimizing risks to personnel and property in the event of a misfire or failure in the targeting system. The projectile effectively becomes a dud, ensuring safety while still providing a clear ballistic path.
