南极普里兹湾冰山高分辨率无人机遥感影像 

封面图像为中国第33次南极考察期间采集的南极普里兹湾冰山高分辨率无人机遥感影像，展示了冰山的分布、几何形态和表面特征。北京师范大学—中山大学极地遥感团队的科研人员在该次考察中使用中国自主研发的极鹰III型（飞马F1000）固定翼智能航测无人机系统，基于该无人机系统的飞控多传感器融合设计、完善的安全处理机制、先进的总能量控制算法，保证了科考飞行数据实时可靠、飞行作业安全稳定及在大风等恶劣天气情况下的航线控制精度，实现了对小型冰山群的高效、精细化监测。相较于传统手段，飞马无人机高分辨率的航测模块与地面基站辅助的高精度无人机定位相结合，能获取冰川冰架的精细地形特征数据，弥补传统卫星遥感的米级分辨率和重访周期固定的不足，在极地科考中具有很大应用潜力。

High-resolution drone remote sensing images of Antarctic Prydz Bay icebergs

The cover image is a high-resolution drone remote sensing image of Antarctic Prydz Bay icebergs collected during China's 33rd Antarctic expedition, showing the distribution, geometric shape and surface characteristics of icebergs. Researchers from the Beijing Normal University and Sun Yat-sen University polar remote sensing team used our country's independently developed Jiying III (Feima F1000) fixed-wing intelligent aerial photogrammetric UAV system during this expedition. Based on the UAV system’s flight control multi-sensor fusion design, complete safety processing mechanism, and advanced total energy control algorithm, F1000 ensures the real-time reliability of scientific research flight data, safe and stable flight operations, and route control accuracy in severe weather conditions such as strong winds, and realizes efficient and refined monitoring of small iceberg groups. Compared with traditional means, the combination of the high-resolution airborne photogrammetric module and the high-precision differential positioning assisted by ground base stations can obtain fine terrain feature data of glaciers and ice shelves, making up for the shortcomings of traditional satellite remote sensing’s meter-level resolution and fixed revisit period, which has great application potential in polar scientific expeditions.
