Bro, Electronic Warfare (EW) will have significant effects on both GPS and Inertial Navigation Systems (INS)
.As the name suggests it affects electronic equipment. Both GPS and INS contain electronic systems.
GPS signals are weak signals and the electronic systems receiving it can be jammed. They can also be spoofed.
INS is inherently EW proof on the surface. But it too can be spoofed and effected by intricate and powerful EW. INS uses gyros and accelerometers (an electro mechanical device). In most drones like Shaheed, they work together with GPS. So they can be spoofed.
Only INS that are used in very sophisticated ICBMs and really expensive seeker heads are not affected by EW.
Apparently, Ukraine is using really fast FPV drones to shoot down Shaheeds.
Ukraine has battle experience with Iranian-made Shahed drones and has mass-produced cheap interceptors.
