- A case of study for Pseudorange multipath estimation and analysis: TAMDEF GPS network Guadalupe Esteban Vázquez B. Dorota A. Grejner-Brzeziska Ciencias de la Tierra GPS TAMDEF multipath Antarctica Pseudorange A research study was conducted to evaluate the amount of pseudorange multipath from GPS (Global Positioning System) observables at TAMDEF (Trans Antarctic Mountain Deformation)network, located in Victoria Land, Antarctica consisting of 33 GPS stations. It is well knownthat, despite carefully selected locations, the GPS stations are to some extent, affected by the presence of multipath. Pseudorange multipath effect for GPS measurements could be apotential contributor that might have an impact on the TAMDEF stations positioning. Thus, the root mean squared error variations (MP1-RMS and MP2-RMS) were estimated and analyzed in order to identify the most and least affected sites, considering GPS data span from year 1996 to year 2006. McMurdo (MCM4) IGS (The International GNSS Service for Geodynamics, formerly the International GPS Service) site, was adopted as part of the TAMDEF network,since MCM4 is the primary ITRF (International Terrestrial Reference Frame) access point for thispart of Antarctica. 2012 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56823338005 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.51
