Thanks for pointing these out. You’re right that the wording around the four-satellite requirement was incorrect — a receiver does not need to be moving to lock onto four satellites; movement may only help improve reception when the view of the sky is obstructed.

The “MAKE command” wording was also incorrect. It should have been documented as the appropriate `make` build step for the repository.

The intent of the article was to provide a practical introduction to GNSS and demonstrate static spoofing, but these points should have been worded more accurately. I appreciate the technical feedback and will get them corrected.
