A number of plugins do this, like mbm or Cinterion. But unfortunately the ublox plugin doesn't support GPS yet, and it turns out we can't yet prevent those known GPS ports from being probed either since they get tagged during the "grab" phase after probing. So nevermind... (though would be good to fix both of these issues).
