The values of regional tidal parameters h₂, l₂ associated with the tidal variations of ground stations were estimated for the Polish Satellite Laser Ranging (SLR) station Borowiec using SLR data. The study is based on satellite observations taken by the global network of ground stations during the period from January 1, 1999 until January 1, 2019 for monthly orbital arcs of the satellites LAGEOS-1 and LAGEOS-2. The adjusted regional values for h₂ equalling 0.7308 ± 0.0008 and l₂ equalling 0.1226 ± 0.0003 are discussed and compared with the nominal values of h₂ and l₂ given in the the International Earth Rotation and Reference Systems Service (IERS) standards and with other estimations of these parameters. Furthermore, the influence of the tidal parameters changes on estimation of the Borowiec station coordinates in the ITRF2014 reference frame was investigated. The analysis was carried out in two variants. The first one consisted in the determination of the Borowiec station coordinates with the use of the nominal values of the tidal parameters: h₂ = 0.6078 and l₂ = 0.0847 (IERS recommended values). In the second one, the Borowiec station coordinates were determined using the local tidal parameters estimated in this paper (h₂ = 0.7308 ± 0.0008 and l₂ = 0.1226 ± 0.0003). The differences between X, Y ,Z for Variant 1 and Variant 2 are −3.5, 3.3 and 4.2 mm, respectively.

使用SLR数据估算了波兰卫星激光测距（SLR）站Borowiec的与地面站的潮汐变化相关的区域潮汐参数h ₂，l ₂的值。该研究基于全球地面站网络在1999年1月1日至2019年1月1日期间对LAGEOS-1和LAGEOS-2卫星的月弧进行的卫星观测。讨论了h ₂等于0.7308±0.0008和l ₂等于0.1226±0.0003的调整后的区域值并将其与h ₂和l ₂的标称值进行比较在国际地球自转和参考系统服务（IERS）标准中给出，以及这些参数的其他估算值。此外，研究了潮汐参数变化对ITRF2014参考系中Borowiec站坐标估计的影响。该分析有两种变体。第一个包括使用潮汐参数的标称值确定Borowiec测站坐标：h ₂ = 0.6078和l ₂ = 0.0847（IERS推荐值）。在第二篇中，使用本文估计的局部潮汐参数确定了Borowiec站的坐标（h ₂ = 0.7308±0.0008和l ₂= 0.1226±0.0003）。变体1和变体2的X，Y，Z之间的差分别为-3.5、3.3和4.2mm。
