Berg says GPS-enabled GSM/WCDMA handsets shipments up 92% in '09
“Chipset developers and handset vendors are already working on next-generation location technologies that will address the limitations of GPS when using handsets in urban canyons and indoors”, said André Malm, Senior Analyst, Berg Insight. “Multi-mode receivers that also support the Russian GLONASS satellite system will appear in handsets in 2011. By combining the two systems, more visible satellites will increase the chance to receive sufficiently strong signals to get a fix in more locations”. He adds that receivers compatible with GPS, GLONASS and later also Galileo will not be enough to enable reliable positioning indoors. In the next decade, further performance increases will come from developments in hybrid location technologies. These fuse signal measurements from multiple satellite systems, cellular networks and Wi-Fi, together with data from various forms of sensors such as accelerometers, gyroscopes and altimeters.
