> The theory that they broadcast communication on a band near GPS in order to discourage jamming of their early warning system sounds likely.
Is it? If it is an early warning system, could it be jammed briefly so it would fail to warn, couldn't it? It will be a global disruption of GPS, but a brief one and I'm sure people wouldn't be concerned of it due to other news.
> Flexing the ability to jam GPS is pointless
Do you believe that cutting sea cables is a sensible action? Or sending drones to neighbors? It is what they call "hybrid asymmetric warfare", I'm not sure how it is supposed to work, but presumably it may let them take over the world or something.
Probably they just strive to normalize deviations, to boil frog slowly. When people become used to some stupid actions they widen their repertoire, until everything short of tanks crossing the borders became just normal news noise nobody reads twice.
Presumably the missile needs GPS to hit the target so if you jam right when the missile is coming in the missile will miss so you can't really jam the warning
Also if you broadcast noise when your missile is about to hit then your own jamming signal acts as an early warning as well, although I guess it wouldn't provide location.
US weapon systems have never relied on GPS for guidance. Some will accept GPS corrections to the primary inertial guidance system but those corrections will be rejected if they deviate more than a few meters from the inertial guidance. US missiles in particular use precision terminal guidance which doesn't involve GPS at all; in these systems GPS would only be used to correct mid-course guidance.
There has been anecdotal evidence for years suggesting that the latest US inertial guidance technology is sufficiently precise and accurate that GPS correction no longer adds value.
ICBMs don’t rely on GPS. They are typically self-guided and use a blend of their known launch location, inertial navigation using gyroscopes, celestial navigation (yes, looking at stars), and a few other techniques.
