Abstract(in English) | In Japan, mobile satellite communication systems are now in service on S-band frequency. Moreover, the Quasi Zenith Satellite (QZS-1) Michibiki has been launched in September 2010, which is expected to start its positioning/navigation experiments soon. Such highly accurate global positioning systems require wide frequency band. In order to ensure highly accurate satellite measurements, knowledge about the wide-band propagation path characteristic becomes important. In urban areas high elevation propagation paths are affected by the building walls and deep fading is generated. Thus, the authors have developed a high satellite elevation angle wall reflection model(HSEA) by measuring high elevation propagation paths from 70 to 88 degrees in the 2GHz and 2.5GHz frequency band. In this paper, the analytical results of the propagation characteristics and the broadband frequency characteristics for a given building environment are presented. |
