Launched on September 15, 2018, from the Vandenberg Air Force Base in Lompoc, California, the NASA Ice, Cloud, and land Elevation Satellite 2, or ICESat-2, carries a photon-counting laser altimeter that allows scientists to measure the elevation of ice sheets, glaciers, sea ice, tree canopy height, ocean height, and more - all in unprecedented ...

ICESat-2 (Ice, Cloud, and Land Elevation Satellite 2), part of NASA's Earth Observing System, is a satellite mission for measuring ice sheet elevation and sea ice thickness, as well as land topography, vegetation characteristics, and clouds. [9]

2024年11月10日 · icesat-2（冰层高度测量卫星2号）是美国国家航空航天局（nasa）发射的一颗用于监测全球冰层覆盖变化的卫星，其主要数据产品包括atl06和atl08等。 【 ATL 06 和 ATL 08 数据产品】： ATL 06是 ICESat - 2 的主要数据产品之一，...

2017年4月3日 · ICESat (Ice, Cloud,and land Elevation Satellite) is the benchmark Earth Observing System mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics. ICESat-2 is the 2nd-generation mission scheduled for launch in late 2015.

这段话是nasa官网对icesat-2功能的极简概括，icesat-2提供电能，推进力，绕轨运动，导航，数据存储操作，定位等，也就是为atlas服务的平台。 贴两张NASA官网的宣传海报，这个海报基本概括了ICESat-2的主要特点，下面我针对海报内容做一些分析与解释。

2024年3月7日 · ICESat-2 measures the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second.

ICESat-2能够指向参考地面轨道精度小于30m，这一精度足以将每次重复运行的观测数据分离。地表坡度越大，dh/dt的误差也越大，ICESat-2的径向轨道精度为2cm，保证了dh/dt的精确测量。ICESat-2激光点在地上的定位误差小于4.5m，可以最大的降低测量高程中的地表坡度影响。

The ICESat-2 mission will provide elevation measurements over the Greenland and Antarctica ice sheets to quantify changes in ice-sheet mass, the mechanisms that drive that change (variations in accumulation, changes in ice melt, or ice flow acceleration/deceleration), and the impact of these changes on future global sea level; monitor changes ...

2025年2月11日 · The Ice, Cloud, and Land Elevation Satellite-2, or ICESat-2, measures the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. Launched September 15, 2018, ICESat-2 carries a photon-counting laser altimeter that allows scientists to measure the elevation of ice sheets, glaciers, sea ice and more – all in ...

2024年5月27日 · 2018年9月15日，美国NASA发射了第二代对地观测激光雷达卫星ICESat-2（Ice, Cloud, and Land Elevation Satellite-2）冰、云和陆地高程”2号卫星。 与上一代相比，新 卫星 采用了量身定制的光子计数激光 雷达 探测系统，也就是人们常说的单光子激光 雷达 ，一举步入光量子 ...
