Indoor Location Positioning Measurement Using Only Smartphone Sensors

In this research, we focus on positioning in places where radio waves from satellites can not reach, such as indoors. We aim at establishment and accuracy improvement of positioning using sensor data of smartphone. The number of steps, stride, and direction are important factors in this research. The previous research has a large error and can not estimate an accurate position. Therefore, we propose position estimation method by adding the newly studied method to the conventional method.
