Putin beordrar styrkor att gå in i Ukraina - INVASION NU (2022-02-24)

By the way, I can explain quite simply why HIMARs is so easily jammed in contradiction to what ‘experts’ claim should be impossible due to its advanced INS. The INS stores coordinates and ‘builds them up’ progressively as the missile gets closer and closer to the target. So yes, if you jam the GPS of the missile not far away from the target, then the INS will have built up enough precision where it can navigate the rest of the way while still maintaining an acceptable CEP.

However, the problem with HIMARs is that they are used solely to strike very distant “rear objects”, not frontline targets. What does that mean? That means the HIMARs missile has to fly upwards of 50-80km over Russian territory to hit something in the rear, and during that entire duration it can be jammed by anti-GPS systems positioned there which means the INS will never even come close to building up an accurate guidance profile yet.

It would be different if the HIMARs was used to strike frontline targets. That means Russian jammers would only be affecting the missile as it already is closing in on the target, which means the INS would have already long built up a profile during the course of its flight. But since they are used to hit rear targets, the missile has to “over fly” Russian jamming territory for many, many tens of kilometers, during which time it flies “in the blind” and cannot build up a proper INS profile, since INS loses accuracy the longer it has to fly without “correction” from the GPS unit.
