摘要

通过多颗卫星传输GNSS全星座电文比由每颗卫星传输时钟和星历更为灵活。消息可以分成分组，并通过不同的卫星进行路由，以优化接收性能。本文提出了基于分组偏移的几种基本路由策略。然后通过蒙特卡罗模拟提出了一种性能分析方法。针对伽利略OS I/NAV信号和整个星座使用的数字签名的传输，提出了特定的策略，并对结果进行了分析，以确定哪种提出的传输策略最适合目标应用。

Packet transmission through navigation satellites: A preliminary analysis using Monte Carlo simulations

The transmission of GNSS constellation-wide messages through multiple satellites can be more flexible than the transmission of clock and ephemeris by each satellite. Messages may be divided into packets and routed through different satellites to optimize reception performance. This paper proposes some basic routing strategies based on packet offsetting. It then proposes a performance analysis methodology through Monte Carlo simulations. Strategies are particularized for the Galileo OS I/NAV signal and the transmission of a digital signature used by the whole constellation, and the results are analyzed in order to determine which of the proposed transmission strategies best serve the target application.
