NASA icesat-2 Project

These Level 1B time-ordered telemetry data are used for system-level, quality control analysis by the Advanced Topographic Laser Altimeter System (ATLAS) ICESat-2 Science Investigator-led Processing System (SIPS). They also provide source data for the Level 2 products and the Precision Orbit Determination (POD) and Precision Pointing Determination (PPD) computations....此类1B级时序遥测数据可供先进地形激光测高系统（ATLAS）及ICESat-2科学研究员主导处理系统（SIPS）开展系统级质量控制分析使用，同时还可为2级产品、精密定轨（POD）与精密指向确定（PPD）的计算提供源数据……
