Just wondering, how does this impact national security? When most of the planet is well-covered by Satellite imagery, isn't finding an installation with 500m difference a matter of searching images?

It's just an excuse to force foreign companies to license the algorithm. There's 0 chance foreign nations don't have a copy of the encryption algorithm.

One the one hand not every rival nation is a spacefaring superpower. On the other, controlling the information available to it's citizens is at least as high a priority for the Chinese authorities as denying it to foreign nations.
