2018年7月14日 · In this paper, we consistently estimate geodetic parameters such as weekly 3-D station coordinates, Earth orientation parameters (EOP) including daily x / y -pole coordinates and the excess length of day \ (\Delta \hbox {LOD}\), and selected weekly Earth’s gravitational field (Stokes) coefficients up to degree and order 6 from Satellite Laser Ra...

Since January 2004 the ILRS official ACs provide every Tuesday individual SSC/EOP loosely constrained solutions, combined and published every Wednesday by the CCs. The individual solutions are based on the analysis of weekly batches of SLR data covering from Sunday to Saturday included.

Earth Orientation Parameters (EOP) Service is operated by the Laboratory of Space Geodesy and Earth Rotation (LSGER) of the Institute of Applied Astronomy of the Russian Academy of Sciences (IAA). The main milestones of the IAA EOP Service history are: Now both operative and final EOP series have being computed.

SLR school 2019 – session 2: Data Analysis Stuttgart, Germany, 20 October 2019

The analysis of Satellite Laser Ranging (SLR) data to LAGEOS, LAGEOS 2 and in recent years, the two ETALON satellites results in a SLR-based realization of the Terrestrial Reference Frame (TRF), complete, with a consistent series of Earth’s Orientation Parameters (EOP) at …

Scientific products derived using SLR and LLR data include precise geocentric positions and motions of ground stations, satellite orbits, components of Earth’s gravity field and their temporal variations, Earth Orientation Parameters (EOP), precise lunar ephemerides and information about the internal structure of the Moon.

2019年2月18日 · Using SLR data to new GNSS systems allows for estimating global geodetic parameters, such as Earth rotation parameters, global scale, and geocenter coordinates.

SLR系统通过对人造卫星进行激光测距，实现卫星轨道与地心固连，确定地球参考架的原点和尺度因子，精化EOP激发机制的分析和提高EOP的预测精度。

Initially, we chose to adjust only EOP in order to compare results and intercompare the GEODYN processing of the two space geodetic techniques. Site coordinates were fixed to a priori coordinates, specifically ITRF2005 for VLBI and LPOD2005 for SLR. The EOP results were compared with IERS C04.

The EOP series are derived from measurements made by independent techniques so that the WRMS difference between each pair of series is the root-sum-square of the precisions of each technique. A 3-corner hat analysis can then be applied …
