星座通信网建设过程中的端到端延时及存储需求分析

为了降低星座通信网建设过程中的端到端延时及星上存储需求，提出了异轨一箭多星(MSMP)方法。在星座通信网每个阶段，该方法把发射的多颗卫星注入到多个相邻轨道平面上合适的相位，使得用户接入卫星的时间窗口分布更加均衡。实验结果表明，MSMP方法在建设过程中的平均端到端延时及存储需求比传统的同轨一箭多星(MSIP)方法分别小70.1%和42.8%。

Analysis on End to End Delay and Storage Requirements During Progressive Construction of Satellite Constellation Communications Network

To reduce the end-to-end delay and storage capacity requirements during the construction of satellite constellation communications network, we propose a concept named multi-satellites into multi-planes (MSMP) scheme. During the construction, satellites launched in each stage were inserted into appropriate positions which could belong to multiple planes. Simulation results show that MSMP scheme can reduce the average end-to-end delay by 70.1% and storage requirements by 42.8% compared to the multi-satellites into 1-plane (MS1P) scheme.
