June 18, 2023: The U.S. Air Force and a MIT (Massachusetts Institute of Technology) Artificial Intelligence project succeeded in developing a MagNav (Magnetic Navigation) application reliable enough to be used in air force aircraft to replace GPS for navigation. . This new MagNav tech was successfully tested aboard a C-17A transport. MagNav takes advantage of the universal presence of magnetic activity worldwide. MagNav uses an AI (Artificial Intelligence) neural network running on a laptop to compare the known location of the aircraft and magnetic activity generated by the aircraft to a worldwide map of background magnetic activity. Once this calibration is done the aircraft can takeoff and fly as far as it has to using MagNav rather than GPS to keep track of where it is. MagNav cannot be jammed and is reliable as celestial (using stars in the night sky) navigation but is more reliable and not disabled by losing sight of the stars.

If MagNav can be adapted to work on guided bombs and missiles it can eliminate the growing problem of GPS jamming or spoofing (misdirecting).
