Air Force Is Looking At Using Magnetic Fields To Navigate Instead Of GPS And

[Kennebec_Captain]

Absolute Positioning Using the Earth's Magnetic Anomaly Field

We present a navigation framework which uses the Earth’s magnetic anomaly field as a navigation signal to aid an inertial navigation system (INS) in an aircraft.

The concept is evidently based on this post.

Working the problem the other way. Instead of plotting the position on the wx chart and looking at the weather just do the reverse. Look at the weather and plot your position.

You’d need both current weather maps and the forecast. Should be good for 96 hours of navigation. [image] Assuming of course the navigator is the “good seaman” of legend. …
