International Laser Ranging Service

The International Laser Ranging Service (ILRS) provides global satellite and lunar laser ranging data and their related products to support geodetic and geophysical research activities as well as IERS products important to the maintenance of an accurate International Terrestrial Reference Frame (ITRF). The service develops the necessary global standards/specifications and encourages international adherence to its conventions. The ILRS is one of the space geodetic services of the International Association of Geodesy (IAG). The ILRS collects, merges, archives and distributes Satellite Laser Ranging (SLR) and Lunar Laser Ranging (LLR) observation data sets of sufficient accuracy to satisfy the objectives of a wide range of scientific, engineering, and operational applications and experimentation.

国际激光测距服务（ILRS）向全球提供卫星和月球激光测距数据及其相关产品，以支持大地测量学和地球物理学研究活动，以及维护精确的国际大地测量参考框架（ITRF）所需的国际地球参考系统（IERS）产品。该服务制定必要的全球标准/规范，并鼓励国际社会遵守其公约。ILRS是国际测量学协会（IAG）的太空大地测量服务之一。ILRS收集、合并、存档和分发卫星激光测距（SLR）和月球激光测距（LLR）观测数据集，其精度足以满足广泛科学、工程和实际应用及实验的目标。
