摘要： 文章提出利用星座星间链路工作时分布在空间的波束为系统外用户提供服务，并对其对一般用户的可用性进行了探讨。基于典型星座星间链路，建立了覆盖区数学模型进行仿真计算，分别从静态和动态的角度分析了星座星间链路在常态工作模式下对于空域的覆盖特性。结果表明：在星座轨道平面附近的用户航天器接收到星间链路信号的机会最多，可直接对系统工作信号接收利用；在星座轨道半径40%~50%附近高度的天球覆盖率最高，达到45%；随轨道半径增加，天球覆盖率降至15%以下，建议对一般用户进行链路规划。

Abstract: The working crosslink beams distributed in space was used to provide services for the external users, and the availability was discussed for the general users. The mathematical model based on the typical constellation structure and crosslink working strategy was established, and the simulation experiments were conducted. Furthermore, the static and dynamic coverage characteristics of the celestial sphere was analyzed. The results show that the users in the vicinity of the constellation orbit plane get the more chance to receive the crosslink signals. And the sphere coverage rate is up to 45% when the height is 40%~50% of the constellation orbit radius, and is below 15% with the radius increasing. As a result, the link planning was recommended for the general users. The conclusions and suggestions may offer new ideas for the crosslink design and provide references for the service scope extending.
