GPS is useful, but not required for operation. Inertial guidance, and ground tracking cameras can easily maintain a good position sense, while completely RF passive. This is also already normal on many toy drones.
You would also want to jam it over a large area. That jamming is akin to a “kick me” sign, in neon lights.
GPS is usually the first thing to be jammed in the battlefield.
