ILRS Analysis Centers
ILRS Analysis Centers fall into three categories: Analysis Centers, Lunar Analysis Centers, and Associate Analysis Centers.
The Analysis Centers (ACs) access and process tracking data from one or more data centers for the purpose of quality control purposes or for the generation of ILRS products. The ACs are committed to deliver the products routinely, without interruption, at an adopted frequency and with a time lag approved by the Governing Board to meet ILRS requirements. The products are generated using designated standards and delivered to the Global Data Centers, to the IERS (as per bilateral agreements), and to other interested bodies. At a minimum, the Analysis Centers must process the global LAGEOS-1 and LAGEOS-2 data sets and are encouraged to include other geodetic satellites in their solutions. It is anticipated that list of satellites to be included in routine analysis by the ACs can be extended if requested by the Analysis Standing Committee and/or the ILRS Central Bureau.
The ACs provide, at a minimum, daily-resolution Earth orientation parameters, weekly-averaged station coordinates and satellite orbits, on a daily basis, as well as other products, required by the IERS. The ACs also provide a second level of quality assurance on the global data set by monitoring individual station range and timing systematic errors via the fitted orbits (primarily based on the LAGEOS-1 and LAGEOS-2 satellites).
Lunar Analysis Centers process normal point data from the LLR stations and generate a variety of scientific products including precise lunar ephemerides, librations, and orientation parameters that provide insights into the composition and internal makeup of the Moon, its interaction with Earth, tests of General Relativity, and solar system ties to the ICRF.
Associate Analysis Centers are organizations that produce special products, such as satellite predictions, time bias information, precise orbits for special-purpose satellites, station coordinates and velocities within a certain geographic region, or scientific data products of a mission-specific nature. Associate Analysis Centers are encouraged to perform additional quality control functions through the direct comparison of individual Analysis Center products and/or the creation of "combined" solutions, perhaps in combination with data from other space geodetic techniques (e.g., VLBI, GPS, GLONASS, Galileo, Compass/BeiDou, DORIS, etc.), in support of the ITRF or precise orbit determination. Organizations that desire to eventually become Analysis Centers may also be designated as Associate Analysis Centers by the Governing Board until they are fully accredited Analysis Centers.
