| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed Spread Spectrum Code Division Multiple Access (SS-CDMA) short message communication using Quasi-Zenith Satellite System (QZSS) for safety confirmation system at the time of large disaster. The proposed system controls the transmission timing using highly accurate time and position information obtained from the QZSS. In order to realize the proposed system, we evaluate the time synchronization accuracy. In this paper, the satellite signal reception error due to sky view factor is evaluated. As a result of evaluating satellite signal reception error, the error amount is 46.0ns in an environment with a sky view factor of 39.0%. It is found that the proposed system has sufficient promise to be realized. |
