摘要

功率通量密度是评估非静止卫星轨道星座系统保护地面业务系统的一项干扰评价指标。基于功率通量密度的定义，给出非静止卫星轨道星座系统固定波束功率通量密度的计算方法，在分析ITU关于非静止卫星轨道卫星固定业务系统的功率通量密度约束条件的基础上，给出确定非静止卫星轨道星座系统功率通量密度限值的方法。以Starlink系统为分析场景，计算分析Starlink测控波束的功率通量密度。结果表明，给出的功率通量密度计算方法与Starlink系统使用方法的分析结果完全一致， 18.55～18.6 GHz频段测控波束功率通量密度不满足限值要求。在当前国际规则框架下，卫星星座规模大小是非静止卫星轨道星座系统合法使用Ka频段的决定性因素。

Abstract

The power fl ux-density is an interference criterion for protecting terrestrial service systems from non-geostationary orbit (NGSO) constellation systems.Based on the defi nition of power fl ux density(PFD)

a calculation method on the PFD produced by the emissions from the fi xed beam of NGSO constellation system was given.On the basis of describing the PFD constraint conditions of the NGSO fi xed-satellite service system given by ITU

a method for determining the limits of PFD from the NGSO constellation system was presented.Taking the Starlink system as the typical scenario

the PFD produced by telemetry

tracking

and control (TT＆amp;C) beam of the Starlink system was analyzed.The results showed that the analytical results of the given method were consistent with those of the Starlink system

and the PFD of TT＆amp;C beam in the 18.55-18.6 GHz frequency band exceeded the limit given in radio regulations.Under the current ITU framework

the number of the satellite constellation is a decisive factor for the legal use of the Ka band by NGSO constellation system.
