alt Hacker News> Before this, everybody in the industry thought GPS solved the aerial navigation problem.
Many people in industry believed this but no one with a brain ever did. The vulnerability of GPS has been cause for concern for a long time, and the decimation of the VOR network has always had a lot of people up in arms.
It seems like we have enough satellites in space that are giving off enough unique signals that we could put together a device that solves the GPS problem without needing GPS itself. I wonder what it would take.
