Abstract
This paper mainly focuses on the combination of station coordinates and ERPs and the realization of TRF based on four technologies GPS, VLBI, SLR and DORIS, and discussed some key points including the combination model, datum definition methods and strategies to the validity of solutions in detail. By comparing our results with ITRF08, the difference in determining the center of mass is 2.4–7.7 mm, the uncertainly error is 1.25 mm; the consistently in scale is 1.10 ± 0.06 ppb; small difference still remains in rotation because of the uncertainly of solutions. As to ERP, the combined solution showed a little difference with C04 and the optimal solution in xpo and ypo, the WRMS compared to C04 is 0.077 and 0.055 mas separately, LOD and UT are fused with DORIS solutions, the combined solution of LOD generally keep a consistency with C04, the WRMS is 0.026 ms, but UT show a large difference and unconsistence with C04 and the optimal solution because it could only be determined by VLBI.
