Several manufacturers were able in the past to reverse-engineering the signal on the second frequency of GPS (enabling cm level precision). Furthermore, the new GPS band (L5) does not have encryption, and new open signal are being deployed also on the L2 band. | |

The distinction between the two is important. This has to do with the notion of an inertial frame in GR, which is different from that in Newtonian mechanics. | |
