摘要	The Earth Rotation Parameters (ERPs) are estimated with the BeiDou Navigation Satellite System (BDS), GPS, and Galileo obser-vations from approximately 100 selected International Global Navigation Satellite System (GNSS) Service (IGS) tracking stations around the world. The results are compared with the IGS final products (IGSF) and the International Earth Rotation and Reference Systems Service (IERS) series 14C04 at 12 UTC. The accuracy of the ERPs derived from the GPS-only reaches the IGS accuracy level. The standard deviations of the differences in the X-pole, Y-pole, and Length of Day (LOD), compared with the IGSF, are 23 mu as, 20 mu as, and 7 mu s/day, respectively. Meanwhile, the standard deviations of the differences in the X-pole, Y-pole, and LOD, in contrast with IERS 14C04, are 28 mu as, 25 mu as, and 9 mu s/day, respectively. Similarly, the ERPs are estimated using BDS-only and Galileo-only observations from approximately 100 selected IGS stations. For ERPs derived from BDS Medium Earth Orbit (MEO-only) satellites, the standard deviations of the differences in the X-pole, Y-pole, and LOD, compared with the IGSF, are 76 mu as, 53 mu as, and 19 mu s/day, respectively, and 75 mu as, 55 mu as, and 19 mu s/day, respectively, compared with IERS 14C04. Likewise, for the ERPs derived from Galileo-only obser-vations, the standard deviations of the differences in the X-pole, Y-pole, and LOD, compared with the IGSF, are 48 mu as, 31 mu as, and 12 mu s/day, respectively, and 48 mu as, 30 mu as, and 14 mu s/day, respectively, in contrast with IERS 14C04. Despite the three orbital planes, tracking station distribution, and unoptimized models for the BDS MEO satellites, these results are close to the IGS accuracy level. The impact of spurious system-specific signals on these solutions is investigated using spectral analysis, a notable spurious signal appears for the 3-plane BDS MEO and Galileo constellations. The pronounced peaks at the frequencies of 2.97 cycles per year (cpy) for Polar Motion and Polar Motion rate, 1.98 cpy for LOD are significantly larger than those from GPS.(c) 2023 COSPAR.
