    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.

      This is exactly how it was done. The missile used can be set to measurement units and only needs GPS occasionally for precision. It was not relying on GPS totally. Ukraine are not going to waste an expensive GPS guided missile when they know it is going to be blocked near the target.

        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.

          Yes it was (reputedly) a GPS weapon that took out the jammer. But it was one that had a back up option for when the GPS was being jammed. It did not just rely on one guidance system. I do not in any way shape or form profess to be an expert on these things. I am going from the opinions of those who are looking closely at stuff like this. Denys Davydov gives his opinion on what was used and why.

          None of these missiles are cheap. Each one fired has a command structure behind it to make it an effective use of the hardware. Remembering Ukraine is under pressure from the US regarding good use of the funds being sent over. The rocket mentioned in the video was GMLRS Munitions. There are much more expensive options that could have been used, but they would not have been an effective use of the funds. This missile has an estimated cost of $225k. There is more to the missile than a single guidance system.
