Satellite Laser Ranging (SLR) ILRS Orbit Prediction Product (multi-day, daily, and sub-daily files) from NASA CDDIS

This derived product set consists of Satellite Laser Ranging Predicted Orbit Product (daily files in Consolidated Prediction Format, or CPF) from the NASA Crustal Dynamics Data Information System (CDDIS). SLR provides unambiguous range measurements to mm precision that can be aggregated over the global network to provide very accurate satellite orbits, time histories of station position and motion, and many other geophysical parameters. SLR operates in the optical region and is the only space geodetic technique that measures unambiguous range directly. Analysis of SLR data contributes to the terrestrial reference frame, modeling of the spatial and temporal variations of the Earth's gravitational field, and monitoring of millimeter-level variations in the location of the center of mass of the total Earth system (solid Earth-atmosphere-oceans). In addition, SLR provides precise orbit determination for spaceborne radar altimeter missions. It provides a means for sub-nanosecond global time transfer, and a basis for special tests of the Theory of General Relativity.

Satellite Laser Ranging (SLR) ILRS Combination Center (CC) Orbit Product (weekly files, generated weekly) from NASA CDDIS

This derived product set consists of Satellite Laser Ranging Final Orbit Product (weekly files, generated weekly) from the NASA Crustal Dynamics Data Information System (CDDIS). SLR provides unambiguous range measurements to mm precision that can be aggregated over the global network to provide very accurate satellite orbits, time histories of station position and motion, and many other geophysical parameters.

It provides a means for sub-nanosecond global time transfer, and a basis for special tests of the Theory of General Relativity. Analysis Centers (ACs) of the International Laser Ranging Service (ILRS) retrieve SLR data on regular schedules to produce precise orbits identifying the position and velocity of satellites equipped with retroreflectors. The ILRS Analysis Center Coordinators (ACC) uses these individual AC solutions to generate the official ILRS final combined orbit products, as well as backup combination. The final products are considered the most consistent and highest quality ILRS solutions; they consist of weekly orbit files, generated on a weekly basis with a typical delay of 3 days. All orbit solution files utilize the extended standard product-3 (SP3) format and span 7 days from 00:00 to 23:45 UTC.

Satellite Laser Ranging (SLR) International Laser Ranging Service (ILRS) Data Handling Files

In the ILRS network, there are mobile systems and permanent systems. Mobile ILRS systems usually occupy (i.e. are referenced to) a ground monument/mark and have an associated set of non-zero eccentricities. System eccentricities are defined as the offsets (usually less than 15 meters) from the ground monument/mark to the optical reference point of the system (i.e. intersection of axes) and are measured in North, East, and Up or in Cartesian coordinates, X, Y, and Z. Mobile systems are assigned a CDP number for the monument that it is occupying. In turn, the IERS assigns a DOMES number for the monument containing a 'M'. The 'M' indicates the presence of a physical Monument. A given monument may be occupied by more than one system or may be occupied by the same system multiple times, but never during the same time period. Therefore, for a given monument and time period, there will be a unique set of eccentricities.Permanent systems were designed to stay in one place and usually do not occupy a ground monument/mark. In this case, the CDP number is assigned to the optical axes of intersection. In turn, the IERS assigns a DOMES number containing a 'S'. The 'S' indicates the reference to the System's optical axes. In this case, the system eccentricities are by definition ZERO. In the rare occasion that a permanent system or its intersection of axes is relocated, then a new CDP and IERS DOMES number will be assigned for each relocation.

International Laser Ranging Service (ILRS) extension of the International Terrestrial Reference Frame 2020 (ITRF2020) TRF Model with additional SLR sites from NASA CDDIS

Expanded set of SLR station positions and velocities in the ITRF2020 frame, includes historical sites NOT part of ITRF2020 and some very recently installed sites that came online in 2022. A small number of sites require special treatment with the addition of corrections to their "mean" positions (in this file) from the ITRS-distributed PSD model, due to "events" (e.g. earthquakes) or changes at the site. Users must apply these corrections cumulatively, to the linearly propagated positions from this file, by themselves. For more details, s/w and relevant correction files please visit the official ITRS site on ITRF2020 at: https://itrf.ign.fr/en/solutions/ITRF2020
