In this paper, data error in sensor system using electromagnetic wave such as GPS and mobile communication is handled. To be specific, a localization that gives acceptable performance in indoor application is considered. The system uses CSS and SDS-TWR to improve system performance. However in multi-path environment, the transmitted signal is corrupted by environment adding reflected signals to the one of line of sight. Three kinds of factors, reflection coefficient, phase difference, and time difference, are related to added noise signals and determined from structural and material characteristics of environment.
