Science and Analysis
The primary objective of the ILRS is to provide a service to support, through analysis of Satellite and Lunar Laser Ranging data and related products, geodetic and geophysical research activities as well as IERS products important to the maintenance of an accurate International Terrestrial Reference Frame (ITRF). The ILRS collects, merges, archives and distributes Satellite Laser Ranging (SLR) and Lunar Laser Ranging (LLR) observation datasets of sufficient accuracy to satisfy the objectives of a wide range of scientific, engineering, and operational applications and experimentation. The service also develops the necessary standards/specifications and encourages international adherence to its conventions.(c.f. ILRS Terms of Reference Introduction)
