Outline of Final Research Achievements

In this research, I investigate a positioning method for pedestrian with smart phone. I develop an absolute positioning method based on the principle of the Real-Time Kinematic Global Positioning Systems (GPS) applied to wireless local area network. By this technique, it is possible to estimate a location of the smart phone with high accuracy even when we cannot observe the signals from the GPS satellites.
Moreover, I develop an estimation method for direction of the pedestrian by using the Inertial Measurement Unit based on the sensors equipped to the smart phone. The sensor values are converted to the world coordinate system. And I estimate the direction using the Principle Component Analysis based on the sensor values. This estimation is very robust because of high degree of the attitude of the smart phone.
