Sony, formerly Sony Ericsson, has announced via its Developer blog that the Japanese company is adding GLONASS support to its Xperia line-up of Android smartphones.
For people unfamiliar with GLONASS, it is Russia’s implementation of GPS (Global Positioning System). GLONASS will work in conjunction with GPS and will allow Xperia handsets to connect to 24 additional satellites for better location accuracy and precision.
Sony’s Positioning Specialist, Magnus Persson, states that GLONASS when combined with GPS can improve the location accuracy by nearly 50% in areas with tall buildings like San Francisco. Persson also states that GLONASS will automatically activate itself when the GPS is struggling to get a proper location. Otherwise, it will remain unused and preserve battery life. Xperia handset owners can find detailed information about GLONASS and how it improves the location accuracy on your handset here.
Apart from the upcoming Xperia Ion and Xperia S, quite a few of the current gen Xperia handsets also support GLONASS. This includes the Xperia Arc, Arc S, Ray, Neo, Play, Live With Walkman, and the Active.
All other major Android handset manufacturers have also started adding GLONASS support in their latest high-end smartphones, including the Motorola Droid RAZR and the Apple iPhone 4S. In fact, Samsung has started including a Barometer in its handsets (Galaxy Note) for ultra-quick GPS lock times as well.
