Abstract
Smartphone easily enables to acquire a high accuracy location information using GPS sensor. Location information is expected to utilize in the field of disaster measures and traffic safety. For example, in a disaster, it is necessary for smartphone users to grasp a high accuracy three-dimensional location information. However, the three-dimensional location information measured by Global Positioning System on the individual smartphone includes many noises by reason of different environment and devises. It is possible that analysis of enormous amounts of probe data can handle the problem mentioned above. However, this is not satisfactory for the uses in emergency as the smartphone lacks real-time performance. In this research, a method for removing noises was proposed for acquiring high accuracy three-dimensional location information from a person trip survey of smartphone in real time.
