| 摘 要： | 基于TDMA的星间链路体制组网灵活,传输效率高,已成为今后星间链路的一种发展趋势。对于TDMA的星座网络而言,其时隙分配是影响业务时延的重要因素,本文就一种双层混合型星座提出了一种时隙分配方案,并对星座网络的传输进行了仿真,分别从广播和单播两种业务的角度针对星间链路传输性能的时延指标进行了评估分析。

| Abstract: | Inter-satellites links based on TDMA system includes flexible networking and high transmission efficiency. It has become a trend of inter-satellites links. For the TDMA system, its time-slot allocation problem is the key factor to influence time delay of the service. This paper presents a time-slot allocation scheme based on visibility between satellites for a double mixed satellite constellation, and makes a simulation of the data transmission, and finally evaluate the network performance separately from the broadcast and unicast two business perspective. |

| Keywords: | TDMA inter-satellites links time-slot allocation delay simulation |
