Abstract :
This paper presents a flexible approach to ubiquitous positioning technologies on smart phone. It deploys three optional indoor/outdoor locating solutions based on Multi-sensor, Satellite, and Terrestrial positioning techniques. The solutions cover six locators including Integrated GPS (Global Positioning System), Bluetooth GPS, AGPS (Assisted GPS), Network based, Multi-sensors, and Wireless LAN (WLAN). In order to merge multi positioning techniques on smart phone, a five-layer software architecture is developed on Symbian S60 platform. Moreover, the implementations of the solutions are described in the paper. Finally, we evaluate the performances of time consumption and positioning accuracy of the solutions according to the experiments on Nokia N95.
