GPS as a Secret 'Numbers Station': What the Evidence Shows

A researcher says a 176-bit GPS field, 'Subframe 4 Page 17', has carried encrypted military traffic for ~19 years.

It is broadcast openly every 12.5 minutes to billions of receivers, hidden in plain sight.

The evidence points to OTAD - the Pentagon's over-the-air system for updating crypto keys.

Nothing has been decrypted; the messages remain unbroken ciphertext.

Your phone's navigation is unaffected - this rides a special field civilians never use.
