Abstract:We propose a new strategy of SLR data short-arc analysis of ETALON satellites in this paper, which also solves satellite orbit parameters, earth rotation parameters and range bias parameters. The new strategy is verified using the data from January to October in 2018. The results show that: the root mean square of residuals for ETALON-1/2 satellites is 1.11cm and 1.08cm respectively; compared with IERS-C04 product, the precision of Xp,Yp and LOD parameters is 2.21 mas, 2.26 mas and 218.30 μs/d respectively; compared with the final orbit of ILRS, the orbit accuracy of ETALON-1 satellite in radial, track and normal direction is 1.6 cm, 8.5 cm and 6.8 cm respectively, while that of ETALON-2 satellite is 2.1 cm, 8.9 cm and 8.7 cm respectively.
