These biases must be considered in any SLR data processing. Indeed, they are strongly correlated with the Up component of the station positions. Thus, if they are not computed together with these positions, they can induce jumps in these latter and consequently damage the global scale factor of the underlying Terrestrial Reference Frame with respect to any given reference. On the other hand, estimating range biases together with station positions is not so easy, due to the previously mentioned correlations. In this paper, we describe a new approach to derive range bias values together with station positions: the so-called “temporal de-correlation” approach. This method consists in computing station range biases per satellite over a “long” period of time (determined by instrumental changes) together with weekly station position time series in order to significantly reduce the correlations.

Analysis of 13 years (1993-2005) of Satellite Laser Ranging data on the two LAGEOS satellites for Terrestrial Reference Frames and Earth Orientation Parameters / David Coulot (2008)

In this context, we have developed a method to compute time series of Earth Orientation Parameters (EOPs) and terrestrial station positions through the analysis of Satellite Laser Ranging (SLR) data. This technique being an important basis for the computation of the International Terrestrial Reference Frame, it is crucial to derive accurate time series with a rigorous approach. Furthermore, this method will be used by the scientific department GEMINI of the Observatoire de la Côte d’Azur when it will become an official ILRS analysis center. These times series are obtained with a good accuracy and a reasonable sampling (1 day for EOPs and 1 week for station positions). This good accuracy is ensured by i) a rigorous weighting of SLR measurements per satellite and per station; ii) a kinematic approach to compute orbital residual errors; iii) a rigorous control of range biases which is detailed in [Coulot et al., 2007]. In this paper, we first present the two aspects i) and ii) of our method. In a second part, we analyze 13 years (1993-2005) of SLR data on both LAGEOS satellites in order to study the Terrestrial Reference Frames and the EOPs so computed.

In the continuation of previous operations on the same site in 2002 the observations programs were carefully tuned to be pertinent on both aspects of scientific goals with new tools to optimize sky coverage for the data and technological issues like maintenance and operational costs. In this paper, we’ll present reports and results concerning station positioning with a very interesting combination of LAGEOS -1, -2, STELLA, and STARLETTE observations and comparison over 2002 and 2005 campaigns. An estimation of final accuracy will be discussed in such experiments of multi occupation site and operational issues will be commented.

Least-square mean effect: Application to the analysis of SLR time series / David Coulot (2008)

Indeed, to compute such series, we in fact estimate constant (typically over one week) updates of station positions with respect to a priori models (ITRF2000, solid Earth tides, polar tide and oceanic loading effects). Thus, these estimations must underline the physical models which were not taken into account in the a priori modeling (atmospheric and hydrologic loading effects and even unknown signals, in our case). As shown through the example of the Satellite Laser Ranging measurement processing, it is not the case: the weekly position time series exhibit weekly means of these physical signals but with a supplementary signal at the level of a few millimeters. This is the so-called “least square mean effect”. To avoid this effect, alternative modeling such as periodic series can be used. A method to compute such periodic series for the station positions together with the geocenter motion is also presented in this paper.
