Probably for AGPS and a better positioning using both GPS chips and other positioning sensors (cell towers, wifi). The Glass GPS antenna is tiny, it can take ages to synchronize without aid.
"Ages" must mean more than half an hour inside a car, then. If I don't have the MyGlass app running on my phone, the location accuracy is so limited that I can only assume it's based on WiFi.
But what do you mean "without aid"? Even without MyGlass running, Glass still has WiFi-based location and an Internet connection (tethering is separate from MyGlass) -- isn't that sufficient for AGPS?
