论文摘要
我们提供了一个公开可用的飞行硬件和软件的工具包，可从平流层气球平台检索5 TB的数据或小型物理样品。在发布之前，气球上附有一个胶囊，并随之升起。在远程命令时，胶囊将释放并通过降落伞下降，不断地传输其位置。预测轨迹的软件可用于选择安全但可访问的着陆点。 2019年9月，我们从超级望远镜上掉了两个这样的胶囊。胶囊花了约37分钟的时间从约30公里的高度降下。他们水平漂流了32公里和19公里，但在预测的着陆点的300 m和600 m内降落。我们很容易找到它们，并成功恢复了数据。我们欢迎其他气球团队的兴趣，这项技术对此有用。
We present a publicly-available toolkit of flight-proven hardware and software to retrieve 5 TB of data or small physical samples from a stratospheric balloon platform. Before launch, a capsule is attached to the balloon, and rises with it. Upon remote command, the capsule is released and descends via parachute, continuously transmitting its location. Software to predict the trajectory can be used to select a safe but accessible landing site. We dropped two such capsules from the SuperBIT telescope, in September 2019. The capsules took ~37 minutes to descend from ~30 km altitude. They drifted 32 km and 19 km horizontally, but landed within 300 m and 600 m of their predicted landing sites. We found them easily, and successfully recovered the data. We welcome interest from other balloon teams for whom the technology would be useful.
