We have seen Samsung add GLONASS GPS Satellite support to their Windows Phone smartphones recently. Now Qualcomm has announced that all S2 Snapdragon processors, which include all current Windows Phones, will have access to this feature, improving GPS navigation reliability and accuracy, especially in dense urban canyons.
OEMs will still have to enable it, but hopefully they will follow Samsung’s lead and continue to make their current devices even better
