本文分析了一种具有可预测接触的无浮标声学至LEO网关。可提前的跨介质准备与声学采集竞争，而残余射频采集消耗接触时间。推导了精确的流体和分组服务、流体最优固定准备提前量、串联队列稳定性以及单接触可靠性。一个显式的服务偏差恒等式表明，为何将采集视为可提前会选取不足的准备提前量。对于对数正态准备，刻画了变异性改善平均服务同时降低可靠性的条件。蒙特卡洛和分组队列模拟用合成参数验证了分析；在一个诊断案例中，考虑残余射频采集将实际可持续速率从8.776提高到9.079 kbit/s。
英文摘要
A buoyless acoustic-to-LEO gateway with predictable contacts is analyzed. Advanceable cross-medium preparation competes with acoustic collection, while residual RF acquisition consumes contact time. Exact fluid and packet service, a fluid-optimal fixed preparation lead, tandem-queue stability, and one-contact reliability are derived. An explicit service-bias identity shows why treating acquisition as advanceable can select an insufficient lead. For lognormal preparation, conditions are characterized under which variability improves mean service while degrading reliability. Monte Carlo and packet-queue simulations corroborate the analysis with synthetic parameters; in a diagnostic case, accounting for residual RF acquisition raises the actual sustainable rate from 8.776 to 9.079 kbit/s.
