According to the Geolocation API Specification there isn't any function for this. Even the option to save it in the browser preferences isn't pushed to your code.

If it's realy important and you realy have to beeing aware of this, you have to write a browser addon for every common browser and ask the user to install it. But i wouldn't doubt of it.
