Abstract Determining precise multi-satellite orbits and geodetic parameters using the satellite laser ranging (SLR) observations to spherical satellites is essential crucial in high-accuracy scientific applications. The weekly combined solutions for orbits, station coordinates Earth rotation (ERPs) SLR LAGEOS, Etalon newly launched LARES-2 are achieved by self-developed software function based on a new processing strategy. We present an in-depth accuracy analysis of determined from solution...
Abstract TianQin project is a space gravitational wave detection initiated by Sun Yat-sen University. It has high requirements for detectors’ orbit accuracy in the stages of entry and scientific experiment operation. We obtain different combinations radial position errors along-track velocity after analyzing detectors according to stability constellation. Satellite laser ranging (SLR) geodetic technique with highest range measurement, which commonly used method satellite determination. This...
Satellite laser ranging (SLR) is the space geodetic technique with highest degree of range, measuring precision and distances right down to millimeter level. Thanks improvement SLR station layouts advance technology, in recent years, more research has been conducted determine Global Navigation System (GNSS) satellite orbits using data.

Abstract TianQin project, a Chinese initiative in space gravitational wave detection, demands high precision satellite orbit during both entry and scientific operations. As means of developmental maturation, ground-based measurements play vital role ensuring the smooth execution satellite’s detection mission. This paper conducts simulation analysis by utilizing various measurement data, including China Deep Space Network (CDSN), S/Ka-band ranging system, Satellite Laser Ranging (SLR). The...
The scale factor serves as a ruler for converting raw phase measurements into physical displacements and significantly impacts the preprocessing of data from Laser Ranging Interferometer (LRI) in laser ranging systems. In current GRACE Follow-On (GRACE-FO) mission low–low tracking gravity satellites, most existing LRI estimation algorithms heavily rely on cross-calibration between instantaneous/biased ranges Ka-Band (KBR) LRI. However, due to nonlinearity objective function (which includes...
