MagNav.

This is coolbert:

Alternative to the Global Positioning System [GPS] has been found?

Jamming of wartime GPS signals no longer going to be a problem?

Never heard of this before. A "demonstration" at this point and that alone?

"MagNav project successfully demonstrates real-time magnetic navigation"

"February 23, 2024: After nearly a decade of effort the U.S. Air Force has finally developed a MagNav (Magnetic Navigation) system that works reliably enough to supplement or replace GPS for navigation. MagNav takes advantage of the universal presence of magnetic activity worldwide. MagNav uses an AI (Artificial Intelligence) neural network running on a laptop, or any other small computer, 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 as well as GPS to keep track of where it is. MagNav will supplement GPS and also act as a backup if GPS is being jammed or encountering some other form of interference. MagNav also does not rely on a network of space satellites to make it work."

Again, MagNav at this juncture just a "demonstration"? A lot more needs to be done before a viable alternative to GPS is do-able? Someone is thinking hard about this, you can be sure.
