Abstract

Here we describe the data obtained by a successful proof-of-concept initiative to launch the first ocean color imager on board a CubeSat satellite and collect research-grade imagery at severalfold higher spatial resolution than any other ocean color satellite mission. The 3U CubeSat, named SeaHawk, flew at a nominal altitude of 585 km. Its ocean color sensor, HawkEye, collected 7,471 research-grade push-broom images of 230 × 780 km at best-in-class 130 × 130 m per pixel. The sensor is built with comparatively low-cost commercial off-the-shelf optoelectronics and was designed to match NASA SeaWiFS ocean color specifications, including wavelengths, bandwidths, and signal-to-noise ratios. HawkEye's design for ocean color remote sensing combined with its high spatial resolution make the imagery especially well-suited for coastal, estuarine, and limnological applications. Ultimately, the successful mission provided open access to a rich global dataset of calibrated and quality-controlled imagery for use in aquatic ecology and environmental change studies.

摘要

在此，我们描述了一项成功的概念验证计划所获得的数据。该计划在一颗立方星卫星上搭载了首个海洋颜色成像仪，并以比其他任何海洋颜色卫星任务高出数倍的空间分辨率收集了研究级图像。这颗名为“海鹰”的3U立方星在585公里的标称高度飞行。其海洋颜色传感器“鹰眼”收集了7471幅研究级推扫图像，覆盖面积为230×780公里，像素分辨率达一流的每像素130×130米。该传感器采用成本相对较低的商用现成光电子器件构建，设计用于匹配美国国家航空航天局（NASA）的SeaWiFS海洋颜色规格，包括波长、带宽和信噪比。“鹰眼”用于海洋颜色遥感的设计及其高空间分辨率，使得这些图像特别适用于沿海、河口和湖泊学应用。最终，这次成功的任务提供了一个丰富的全球校准和质量控制图像数据集的开放访问权限，可用于水生生态和环境变化研究。
