If you have "Use Wireless networks" checked in the Location settings, you maybe getting an approximate location based on the cell-towers or Wi-Fi APs near you. This is not true GPS.
If you do not have that option checked and are still getting an accurate fix, please let me know as I am very interested in how you got it working since apparently the GPS API has been updated since even apps like GPSTether will not work.
This gapps, fix the calendar issues :)
