摘要

在平流层的高空平台(HAP)和卫星之间，高数据速率光链路是可以想象的，但挑战仍然没有明确确定。因此，我们审查适当建立这种联系的主要要求。HAP-LEO链路的设计在几个方面与HAP-GEO链路不同。其中，我们考虑了大气传播、太阳和HAP终端环境可能造成的限制。当光束必须在HAP视界附近或以下传播时，信号传输明显变得更加困难。

System requirements for optical HAP-satellite links

Between a high-altitude platform (HAP) in the stratosphere and a satellite, high-data-rate optical links are conceivable but the challenges are still not clearly identified. We thus review the main requirements to properly establish such links. The design of a HAP-LEO link is in several aspects different from that of a HAP-GEO link. Among others, we consider the possible limitations caused by atmospheric propagation, the Sun and the environment of the HAP terminal. Signal transmission appears markedly more difficult when the optical beam must propagate near the HAP horizon or below.
