摘要

WRC-2003通过了第141号决议，审查使用高倾斜轨道(HIO)的卫星系统在17.7-19.7 GHz频段的现行PFD限制规定，并通过了相关议程项目1.18，为下一次WRC会议做准备。为了评估当前的PFD掩模是否适合保护地面固定业务(FS)免受HIO卫星的干扰，采用MOLNYA、VIRGO和NSAT三种HIO系统，对接收到的FS站受HIO卫星发射的干扰水平进行了分析。作为研究的初步结果，本文建议采用适当的PFD限制掩膜来保护韩国FS站免受此类HIO卫星发射的干扰

Analysis of PFD levels of earth surface from HIO satellites in the 17.7-19.7 GHz band

WRC-2003 resolved a resolution 141 to review the provisions of current PFD limits in the band 17.7-19.7 GHz for satellite systems using highly inclined orbits (HIO), and adopted a related agenda item 1.18 in preparation for next WRC meeting. In order to review whether the current PFD masks are appropriate to protect terrestrial fixed service (FS) from HIO satellites, analyses of received interference levels of FS station from the emission of HIO satellites were carried out using three kinds of HIO systems, such as MOLNYA, VIRGO, and NSAT type systems. As a preliminary result of the study, this paper suggests an adequate PFD limit mask to protect Korean FS stations from the interference due to emission of such HIO satellites
