This study has showed, in one hand, the feasibility of precise calculation of a SLR network, Earth orientation parameters (EOP) and transformation parameters, by using four years observations of low satellites namely Starlette and Stella and, in other hand, the methodology of analysis adopted for this work.

The Earth's rotation parameters during the period are deduced. It is concluded that, if the laser tracking is sufficiently uniform along the entire orbit, then the 5-day arc solution can reach a decimeter accuracy and the laser ranging data on STARLETTE can complement those on LAGEOS in a precise evaluation of the Earth's rotation : He Miao-fu.

With the improvement of the Starlette force model by simultaneous estimation of selected geopotential coefficients and ocean tide parameters, the weighted rms of the Starlette solution with respect to LAGEOS was reduced to 9 mas and 6 mas for ∆x and ∆y, respectively.

Abstract. The high-quality satellite orbits of geodetic satellites, which are determined using Satellite Laser Ranging (SLR) observations, play a crucial role in providing, e.g., low-degree coefficients of the Earth's gravity field including geocenter coordinates, Earth rotation parameters, as well as the SLR station coordinates.

The monthly SLR normal point observation summary files report on one month of SLR data from a global network of stations ranging to satellites. The LAser GEOdynamic Satellite (LAGEOS) was designed by NASA and launched May 4, It was the first spacecraft dedicated exclusively to high-precision laser ranging and provided the first opportunity to acquire laser-ranging data that were not degraded by errors originating in the satellite orbit or satellite array.

The Y Neglecting the estimation of geopotential parameters for Starlette, Stella, and AJISAI, leads to a serious orbit. Laser ranging is possible even when the satellite is in the earth's shadow and during daylight hours. Simultaneous laser ranging to a near-earth satellite from two sites is used to determine the coordinates of one laser site relative to the fixed position of the other site and simultaneously the inter-site distance.
