Too bad it is regional rather than worldwide. It would be nice to have back up systems in case our own government decides to screw with the system. Right now the tablet I’m using can track both the US and Russian systems.

Or am I missing something?
That system is going to require a lot of complex math — fortunately, the help desk will be a local call.
