civilian GPS operates at a few fixed frequencies like 1575.42 MHz, 1227.60 MHz, and L5 at 1176.45 MHz (plus 2-3 more; military GPS is a different story). The structure of the GPS data is also fairly well known; all of this is easy to find on the goog.
So you hop on the same frequency start spamming bad GPS data. wrong time stamps, wrong satellite info, etc. with a little effort you can convince a long range missile they’re off by 2 miles and should veer left hard.
or you just put a shit ton of noise on the same frequencies and make it so it’s forced to use inertial navigation (which isn’t very accurate).
