SUMMARY:Mobile Phone Positioning: Improving GPS Performance - Nicolas Cour
 onneau (Cavendish Astrophysics)
DTSTART:20120306T163000Z

UID:TALK35853@talks.cam.ac.uk
CONTACT:David Titterington
DESCRIPTION:Most mobile phones now include positioning capabilities\, whic
 h rely on a GPS receiver or the triangulation of cellular base stations.  
 The device location is used in popular applications\, such as Google Maps\
 , and is also a requirement for processing emergency calls.  However\, the
  availability\, the speed\, and the accuracy of the position is highly var
 iable.\n\nIn this talk\, I will present some of my PhD work on the acquisi
 tion of GPS signals on mobile phones.  I will introduce the basics of GPS 
 and cellular networks operations. I will show how the stability of the cel
 lular networks can be used to improve the acquisition of GPS signals.  Res
 ults of experiments on European (GSM) and North American (CDMA2000) networ
 ks will be presented.\n
