GPS is almost never used for military guidance systems compared to inertial dead reckoning, GPS is too unreliable and easy to jam!

- sudosysgen 2y agoThat isn't true. Inertial guidance systems that work for appreciable flight times are too expensive. Many military systems do use GPS, such as HIMARS, Excalibur, JDAMs, etc... If I had to guess, the reason why the above are jammed and the UMPK isn't is because of better integration with the launch platform and a shorter flight time leading to less inertial drift over time, plus a very large warhead to make up for inaccuracy.
