我们研究了距离偏差所采用的策略对卫星激光测距数据处理结果的影响。更特别的是，我们测试了每周计算的陆地参考系比例因子的稳定性。 ITRF2000根据本文研究的两种不同策略。在第一种方法中，数据处理中不考虑范围偏差。在第二种方法中，我们使用时间去相关方法来严格估计所有站点范围偏差。第一种方法提供具有分段行为的每周比例因子。更准确地说，时间序列在 2001.0 和 2006.0 之间表现出 -2.5±0.2 毫米/年的漂移，并提供 5.2 毫米的 RMS。第二个
We examine the impact of the strategy adopted regarding range biases on Satellite Laser Ranging data processing results. More especially, we test the stability of the weekly Terrestrial Reference Frame scale factors computed w.r.t. ITRF2000 accord- ing to the two different strategies which are studied in this paper. In the first approach, range biases are not considered in the data processing. In the second approach, we use a temporal de-correlation method to rigorously estimate all station range biases. The first approach provides weekly scale factors with a piece-wise behavior. More precisely, the time se- ries exhibit a drift of −2.5±0.2 mm/yr between 2001.0 and 2006.0 and provide a RMS of 5.2 mm. The second
