For more than half a century, the technique of Satellite Laser Ranging (SLR), which measures the round-trip time-of-flight of ultra-short laser pulses emitted by a station to an artifical Earth orbiter, e.g., a satellite, and back to the station, is widely-used in geodetic and geophysical research studies. With its indispensable contribution to the determination of geodetic parameters, e.g., the geocenter and station coordinates, SLR is essential for the realization of long-term stable terrestrial reference frames. Although nowadays the Earth’s time variable gravity field is determined by dedicated satellite gravimetry missions, e.g., Gravity Recovery And Climate Experiment (GRACE) and GRACE Follow-on, some of the low-degree Spherical Harmonic (SH) geopotential coefficients are still better determined by SLR. To investigate the scientific potential of SLR, weekly multi-satellite SLR solutions, where the orbits are determined in 7-day arcs simultaneously with station coordinates and other geodetic parameters, e.g., SH geopotential coefficients and Earth rotation parameters, are performed. These solutions will cover all 'three pillars' of geodesy, i.e., geokinematics, Earth rotation and the Earth's gravity field, and, therefore, ensure a highest possible level of consistency. The quality of the estimated parameters is validated by comparison with internal and external reference series.
