| Abstract(in English) | This paper deals with the L-band satellite diversity (Sat. D) system and tine delayed diversity (TDD) system characteristics for mobile broadcast geostationary satellite orbit (GSO) system, which is measured by using the GPS (Global Positioning System) satellites in Sapporo and Asahikawa cities. Even though the difference of city constitution (i.e. building density, height, width of roads etc .), relative common satellite visibility improvement characteristics can be obtained. Concerned about the effect of TDD system characteristics, about 3-5 minutes delay times are adequate, and satellite visibilities can be improved about twice. In the Sat. D system, about 50 % satellite visibility without Sat. D system can be improved to 90 % satellite visibility by adopting the Sat. D system in both cities. |
