Russia installed a radio-jammer that interferes with the signals that direct GPS-guided munitions. Last week, Ukraine blew it up ... with a GPS-guided bomb.
I bet the jammers were unsophisticated enough you could just program the GPS to continue moving in the direction where the over the air noise levels kept increasing.
For all the legitimate criticisms of Russian military, their EW and Counter-EW capabilities are actually world class. Which is why it is a big deal when they’re destroyed, or captured.
I’m not sure I follow you. If the missile is using gps for guidance(during at least part of it’s flight), then it is by definition a gps quided rocket is it not?
Also, gps quidance isnt terribly expensive. I use industrial grade units which go for about 3kusd and provide sub-metre accuracy in highly gnss denied enviroments. Lower grade ~3m accuracy units go for around a hundred dollars, and would be completely sufficient for hitting a target the size of a truck.

Depending on the range at which the signals start to become jammed, it could be possible to navigate solely by IMU for the final leg also.
