“…Generally, this technique is based on measurement data for geophysical satellites SPOT1-5, TOPEX/Poseidon, Jason1-3, Envisat and others. The method of satellite orbits, station positions and velocities estimation for all techniques is given in (Altamimi et al 2011), but on the basis of the SLR technique is described, e.g., in Lejba and Schillak (2011), Rutkowska and Jagoda (2010), Sośnica (2014). Methodology and data analysis for the DORIS technique are described in details by (Cretaux et al 1998) and (Soudarin and Cretaux 2005).…”

This paper concerns an analysis of the accuracy of the estimated parameters X (U, K, x) which define the tectonic plate motions. The study is based on the velocities of station positions in the IERS (International Earth Rotation and Reference Systems Service) which has published new realization of the International Terrestrial Reference System-ITRF2008 for Doppler Orbitography by Radiopositioning Integrated on Satellite DORIS technique. Eurasian, African, Australian, North American, Australian, Pacific, Antarctic and South American plates were used in the analysis. The influence of the number and localization of stations on the plate surface on the estimation accuracy of the tectonic plate motion parameters were discussed. The results were compared with the APKIM 2005 IGN model and our earlier estimation for the SLR technique. In general, a remarkable concurrent agreement between the present and the APKIM 2005 solutions was found.

“…It is commonly used either to calibrate the accuracy or to compensate the error of satellite's orbit determination [5], to determine the station coordinates [6,7], Earth orientation parameters (EOP) [8], and tidal parameters [9,10]. Studying the Earth's gravity field, the ocean tide models [11,12], and the elasticity [9,13]. However, due to the limitation of observation (weather) conditions, it generally needs to work together with the orbital dynamic models with long measurement arcs for dynamic orbit determination.…”

The TianQin Project is aiming at gravitational wave (GW) detection in space. TianQin GW observatory comprises three satellites orbiting on $1 \times 10^5$ km Earth orbits to form an equilateral-triangle constellation. In order to minimize the variations of arm-length and breathing angle, the satellites must be launched and adjusted precisely into an optimized orbit. Therefore, satellite laser ranging must be used to enhance the precision of satellite’s orbit determination. To develop the capability of satellite laser ranging for TianQin’s orbit, the TianQin Laser Ranging Station has been designed and constructed to perform high-precision laser ranging for TianQin satellites and lunar laser ranging as well. Applying a 1064-nm Nd:YAG laser with 100-Hz repetition frequency, 80 pico-second pulse duration, and $2 \times 2$ array of superconducting nanowire single photon detectors, we have obtained the laser echo signals from the five lunar retro-reflector arrays, and the measurement data have been packaged into 234 normal points, including a few data measured during the full-moon lunar phase. Each NP is calculated from continuous measurement for about ten minutes and the statistical error of the normal points is about 7 mm (1$\sigma$).

“…BORL station is currently observing space debris objects and satellites. The results of the SLR observations of satellites are used to determine positions and velocities of the stations Schillak, 2011, Schillak et al, 2021), earth orientation parameters (Sośnica at al., 2014), tidal parameters , the ocean tide models (Sośnica, 2015) and study the Earth's gravity field (Sośnica et al, 2012).…”

In 2014, a significant upgrade was made to the Borowiec (BORL 7811) laser-ranging system, which is the part of Space Research Centre of the Polish Academy of Sciences (SRC PAS). Two high-energy lasers modules were installed. First is the EKSPLA PL-2250, used for tracking objects equipped with retroreflectors. Second is the Continuum Surelite III, dedicated to the tracking of space debris without retroreflectors. In 2016, the BORL station joined the space debris tracking laser group and, since then, is tracking systematically inactive/defunct satellites and typical rocket bodies from LEO regime. Today, the BORL is tracking regularly about 80 different space debris objects. The paper presents the activity of the BORL laser station in observations of space debris. The results presented are from years 2016 to 2020. The sum of all passes from this period is almost 2 000, giving over 23 000 normal points. Average root mean square error (RMS) of objects with satellite laser ranging-dedicated (SLR-dedicated) retroreflectors ranges 1.5 cm–14 cm and of objects without SLR-dedicated retroreflectors ranges 8 cm–222 cm.
