WAAS only works in North America. I don't know details elsewhere, but the
PMTK313 message says it turns searching for SBAS satellites on and off.

Thanks for the information on the messages, Jim.

For your information, in Europe we have EGNOS, which works in the same was 
as WAASfrom a different set of geostationary satellites.


I have not WAAS/EGNOS tested on the MT3339 chipset, but it does work on my 
Garmin GPS 60 CSx.  I don't know whether the iPad uses WAAS/EGNOS, or my 
Moto-G phone, but the latter can see GLONASS as well as GPS, which I didn't 
know until I checked it after the recent GLONASS outage.
