摘要：

首先，阐述了卫星固定业务地球站和近地空间研究业务地球站工作在8 450～8 500 MHz 频段的特性参数。其次，针对卫星固定业务地球站对于近地空间研究业务地球站的干扰进行讨论，并计算保护近地空间研究业务地球站所需的保护地理隔离距离。对于近地空间研究业务地球站的保护问题，采用《无线电规则》规定的最大等效全向辐射功率谱密度计算包括非静止卫星系统和静止卫星系统在内的干扰情况。计算结果显示，为了达到近地空间研究业务地球站的保护标准，在近地空间研究业务地球站周围需要达到542～582 km的保护地理隔离距离。

Abstract:

Fixed-satellite service earth stations and space research service earth stations parameters in the 8 400～8 500 MHz band were introduced.Then the interference from fixed-satellite earth stations to space research earth stations was examined and the required separation distances for protection of space research earth stations were calculated.For the protection of space research earth stations,both the non-geostationary-satellite and geostationary-satellite systems using maximum equivalent isotropically radiated power spectral density values allowed per“Radio Regulations”were covered.The result shows that required separation distances in the range from 542 km to 582 km around near-earth space research service earth stations would need to be established in order to meet the protection criteria of the near-earth space research earth station.

Key words: compatibility calculation, fixed-satellite earth station, space research service earth station, interference, protection distance
