It is intended for studying the Lense\u2013Thirring effect resulting from general relativity as well as for geodynamic studies and satellite geodesy. The satellite is observed by most ground laser stations. The task of this work is to determine the station coordinates and to assess the quality of their determination by comparison with the results from the LAGEOS-1 and LAGEOS-2 satellites. Observation results in the form of normal points (396,105 normal points in total) were downloaded from the EUROLAS Data Center for the period from 29 February 2012 to 31 December 2015. Seven-day orbital arcs were computed by the NASA GSFC GEODYN-II software, determining the coordinates of seventeen selected measuring stations. The average Root Mean Square (RMS) (15.1 mm) of the determined orbits is nearly the same as for LAGEOS (15.2 mm). The stability of the coordinates of each station (3DRMS) is from 9 mm to 46 mm (for LAGEOS, from 5 mm to 15 mm) with the uncertainty of determining the coordinates of 3\u201311 mm (LAGEOS 2\u20137 mm). The combined positioning for the LARES + LAGEOS-1 + LAGEOS-2 satellites allows for the stability of 5\u201318 mm with an uncertainty of 2\u20136 mm. For most stations, this solution is slightly better than the LAGEOS-only one.<\/jats:p>","DOI":"10.3390\/s21030737","type":"journal-article","created":{"date-parts":[[2021,1,25]],"date-time":"2021-01-25T09:59:40Z","timestamp":1611568780000},"page":"737","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Analysis of the Quality of SLR Station Coordinates Determined from Laser Ranging to the LARES Satellite"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8637-3603","authenticated-orcid":false,"given":"Stanis\u0142aw","family":"Schillak","sequence":"first","affiliation":[{"name":"Centrum Bada\u0144 Kosmicznych Polskiej Akademii Nauk (CBK PAN), 00-716 Warszawa, Bartycka 18A, Obserwatorium Astrogeodynamiczne CBK PAN, 62-023 Bor\u00f3wiec, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1695-3298","authenticated-orcid":false,"given":"Pawe\u0142","family":"Lejba","sequence":"additional","affiliation":[{"name":"Centrum Bada\u0144 Kosmicznych Polskiej Akademii Nauk (CBK PAN), 00-716 Warszawa, Bartycka 18A, Obserwatorium Astrogeodynamiczne CBK PAN, 62-023 Bor\u00f3wiec, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr","family":"Micha\u0142ek","sequence":"additional","affiliation":[{"name":"Centrum Bada\u0144 Kosmicznych Polskiej Akademii Nauk (CBK PAN), 00-716 Warszawa, Bartycka 18A, Obserwatorium Astrogeodynamiczne CBK PAN, 62-023 Bor\u00f3wiec, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,23]]},"reference":[{"key":"ref_1","unstructured":"ESA, eoPortal Directory (2020, November 10).
