Emergency Location Service from android

A new service introduced by android that is Emergency Location Service.
This service locates exact location of the caller who attempt an emergency call.
Its very tough to locate exact location of the mobile caller from mobile networks,like it first locate signal towers but its never locate exact location of the caller because it finds signal tower (but it can have a radius of upto several kilometers ). Gps also fails in indoors.
To address this issue android started this service.
It will locate exact location of mobile caller's when they use emergency services.  This is supported by over 99% of existing Android devices (version 2.3 out and upwards) through Google Play Services. The service activates when supported by your mobile network operator or emergency infrastructure provider.
This service is already live today for people with Android phones in the UK and in Estonia. Hope this expand internationally soon.
