Skyhook Wireless' XPS 2.0 positioning system now combines signals from cellular broadcast towers to its hybrid WiFi and GPS system.
The original version of XPS delivered multi-mode location switching between WiFi-based positioning and GPS readings based on availability and error estimates.
XPS 2.0 algorithmically combines raw WiFi, GPS, and cell tower readings to produce a single hybrid calculation, according to SkyHook.
In indoor and urban environments, XPS can use signals from just two GPS satellites to improve WiFi location accuracy by 35 percent, Skyhook said.
In a typical deep urban setting, assisted GPS can only produce a location 70 percent of the time outdoors, Skyhook said, while XPS 2.0 can achieve accurate location 100 percent of the time.
The company further says the technology can determine position from a complete cold start in just four seconds, which also adds to power conservation.
This latest version of XPS also introduces vertical location capability. As part of the XPS 2.0 launch, Skyhook Wireless is also introducing its first cellular positioning system.
The system covers major US and European cities. Skyhook plans to expand coverage to a global basis by the end of this year.
