【 摘 要 】

The paper presents estimates of local tidal parameters (Love and Shida numbers) h2, l2 for the Riga (No. 18844401, Latvia) satellite laser ranging station based on LAGEOS-1 and LAGEOS-2 data for a period of 15 years (01.01.2004–01.01.2019). The adjusted values for h2 = 0.6891 ± 0.0009 and l2 = 0.1043 ± 0.0004 are discussed and compared with the nominal values of h2 = 0.6078 and l2 = 0.0847 given in International Earth Rotation and Reference Systems Service standards. The differences of the coordinates of the Riga station in International Terrestrial Reference Frame ITRF2014 evaluated using the nominal and adjusted values of the tidal parameters are 4.4 mm for the X component, 4.7 mm for the Y component and 6.9 mm for the Z component.
