Tailwind lets an aircraft navigate visually when GPS is jammed or spoofed, from take off through landing. It comes as a 475g payload that bolts on, or as software with no extra hardware at all, running on the cameras and compute the aircraft already carries. That second path is what makes it scale: lifetime cost drops sharply and the capability spreads across an existing fleet without buying new airframes. Tailwind is passive, so it stays quiet in the spectrum.
