    Re: New Scientist: GPS mystery is making ships appear to teleport and move in circles

    Paul Saffo,

    Thank you for the link. This one is new to me. At first glance, it sounds similar to the spoofing incidents reported in Chinese ports last year, but this is something quite different.

    The New Scientist article appears to be behind a paywall. There is also coverage (no paywall) from GPS World here:
